2. Commands In this manual, unless otherwise specified, any “key” refers to the keys on a PC keyboard. The “screen” referred to is the PC monitor screen. 2-1 Command mode and Converse mode The typical operating modes of this unit are the Command mode and the Converse mode. It is necessary to use the command mode to set internal parameters, or execute immediate direct commands in the EJ-50U. When the unit is in the command mode, the “cmd:” prompt will appear on the screen.
2-4 Command chart The following is a chart for the commands commonly used in Amateur Radio communications.
ECHO E ON ON/OFF Activates echo back of your keystrokes on the 3-2-4 computer screen EPATH EPATH N/A Call1, --, Call7 8-3-9 EXTCLR FILE FIRMRNR EXTC FI FIR N/A N/A OFF N/A N/A ON/OFF FLOVER FL 0 0-120 FLOW F ON ON/OFF FRACK FULLDUP FR FU 3 OFF 0-15 ON/OFF GBAUD GB 4800 4800/9600 GPSSEND GPSS N/A GPSTEXT GPST $PNTS 159 characters 6 characters HBAUD HB 1200 1200/9600 HEALLED HID HEAL HI OFF ON ON/OFF ON/OFF ID KILL I KI N/A ON N/A ON/OFF Sets digipeater list

When ON, displays digipeat route in the header. 4-7-1 4-7-5 MSTAMP MYCALL MS MY OFF NOCALL ON/OFF 6 characters +SSID Applies date/time to the header Sets your callsign in the TNC 4-7-7 4-1-2 MYALIAS MYA N/A Sets the “name” of your Digipeater.
STREAMSW STR $01 0-$7F Sets character used to change STREAM 9-1-2 TOUT TRACE TOUT TRAC 30 OFF 0-250 ON/OFF Message Board time-out parameter Displays the contents of all received frames. 10-1-3 4-7-6 TRANS T N/A N/A Enter the transparent mode. 6-3-1 TRFLOW TRF OFF ON/OFF TRIES TRI 0 0-15 TXDELAY TX 50 0-120 Flow-control in the transparent mode.
3-2 Relative commands 3-2-1 ABAUD command Abbrev. AB default 9600 parameters: 600,1200,480,9600,19200 example AB 15200 Function: Sets the serial communication speed to the host. YOU MUST REBOOT by using the RESTART command or reboot when in the back-up mode. This value must match the speed of the host terminal communication port. 3-2-2 AWLEN command Abbrev. AW default 8 parameter 7/8 example AW 8 This is used to set the data length for serial communication with the host.
3-2-7 AUTOLF command Abbrev. AU default ON range ON/OFF example AU ON When on, it puts a line-feed [LF] code after the carriage return [CR]. This is to match the parameters of the terminal software such as [CR] RX, [CR]/[CR]+[LF]. The incorrect setting may result in overwriting of the new message onto the displayed message or if excessive line feeds occur. 3-2-8 FLOVER command Abbrev.
4-1-3 CALIBRA command Abbrev. CAL default: none parameter: none Example: CAL By using this command, the TNC enters the calibrate mode and outputs mark and space characters alternately. This is useful for checking the transmitter or for setting transmit deviation. Type [Q] key to exit. In the 1200 bps mode, 1200 and 2200Hz signals are output alternately.
(1) (2) (3) (4) (1) As it goes to transmission, PTT turns ON and starts transmitting the Flag signal. The Flag signal is to show the partition of the packet and to synthesize the data clock. (2) The data transmission is held until the TXDELAY time elapses. The TXDELAY must be calculated including the physical timing of the RX/TX change of the radio, and the Flag period of the reception side of the packet.
4-2-6 TXDELAY command Abbrev. TX default 50 parameter: 0 to 255 Example: TX 80 This is to determine the waiting time between PTT on and the transmission of the packet, in units of 10 microseconds. During the TXDELAY period, the Flag signal is transmitted. This Flag signal is used to divide frames and to allow the radio to synthesize. Please calculate enough time for the Flag signal based on the physical TX/RX change on the transceiver, and synthesizing timing.
accepted. Please leave this parameter OFF for error-free communication. 4-4 Connected for 2way communications (being connected) In the connected communication mode, in accordance with the AX.25 protocol, data is exchanged with “Yes, I got it” or “I didn’t get it, please retransmit” kind of information. If the confirmation (“I got it”) is not received after transmission, the TNC retransmits the data. In this chapter the following commands will be explained.
is sent. 4-4-7 FRACK command Abbrev. FR default: 3 parameter: 0-250 example: FR 5 When you are “on-line” (connected) and the transmitted information frame (I frame) is received at its destination correctly, you receive a “Yes, I got it” (RR frame). If a certain time has elapsed but you still don’t get a reply, the I frame will be transmitted again (retry feature). Beside I frames, and a connection request frame (SABM frame), there are frames that require a reconfirmation from the destination.
status. This may result in poor communications efficiency by sending packets that will not be received. 4-4-12 CONSTAMP command Abbrev.:CONS default: OFF parameter: ON/OFF example: CONS ON When ON, adds date and time to the displayed packet when connected or not. ON: When the date and time is previously set using DAYTIME command, the date and time of connection will appear on the display. OFF: It does not appear on the display when connected.
When they reach pre-determined length: PACLEN When the pre-set time is elapsed: PACTIME and relative CPACTIME You may transmit different frames as one packet. The maximum number of these frames can be determined with MAXFRAME command. 4-6-1 SENDPAC command Abbrev.
PACTIME command becomes effective when ON is selected. The PACTIME command is not automatically effective on the EJ-50U. 4-6-7 MAXFRAME command Abbrev. : MAX default: 4 parameter: 1-7 Example: MAX 7 This command sets a limit on the number of packets that have not been acknowledged by the receiving station. Since the size of the EJ-50U’s transmission buffer is limited, the number of outstanding frames and the size of those frames must be considered.
Command/Response [C] command [R] Response Sequences [Rn] Receiving sequences. n=0-7 [Sn] Transmitting sequence n=0-7 4-7-3 MCON command Abbrev. MC default OFF parameters: ON/OFF Example: MC ON This allows you to monitor frequency activity even when connected to another station. ON allows you to monitor while you are connected. OFF does not. 4-7-4 MALL commands Abbrev. MA default: ON parameter: ON/OFF Example: MA ON When ON, all stations will be monitored, connected and unconnected.
5-2 Compatible GPS The following GPS receivers are compatible with the EJ-50U: (1) SONY’s IPS-5000 series, IPS-3000 series, PACY-CNV10 and other GPS receivers that output the data starting with [SONY xxxxxx]. The Sony Car-Navigation system receiver that generates a data string starting with [SMATC xxxx] may work, but we do not guarantee its function, as the format of this string is not officially published. (2) NMEA-0183 compatible output GPS receivers.
6 : day 090346 : Current time in UTC N : N for North, S for South to indicate the latitude 3546569: the latitude in degree. This number can be shown in DMD (NEMA) or DMS that is selectable with a command. The identifier will appear on the later part of the data. In the DMD (NEMA) system it means 35’46.569”, in DMS it means 35’46”56.9’’’. E : E for East, W for west to indicate the longitude. 13918458: The longitude in degrees. In DMD 139’18.458”, in DMS 139’18’’,45.8’’’.
0.9 Horizontal dilution of position 545.4,M Altitude, Meters, above mean sea level 46.9,M Height of geoid (mean sea level) above WGS84 ellipsoid (empty field) time in seconds since last DGPS update (empty field) DGPS station ID number 5-4-4 $GPVTG One of the NMEA-0183 formats. Only the speed and direction can be detected. The EJ-50U can analyze and re-structure this format. The data contains the following information: *$GPVTG: starts GPVTG sentence True course direction in degree related to the North.
Direction in degrees Date in dd/mm/yy format. The difference of magnetic direction from true north. To which direction the magnetic direction differs. E toward east, W toward west. Hh the check-sum and the end of the message. 5-4-7 $GPGLL One of NMEA-0183 formats. latitude, longitude, and time can be detected. EJ-50U can analyze and re-structure this format. The data contains the following information: Starts $GPGLL sentence. Latitude in numbers N for north, S for South. The data status.
The numeric digits usually vary its length, sometimes without the decimal numbers. In order to keep a fixed length of data, 0 is added before a number like 001 to indicate 1. The check-sum may be eliminated. Numbers followed by * , or even * itself is sometimes eliminated. 5-5 Details of GPS data processing In the EJ-50U, data in the LTXT buffer will be sent out as a beacon.
example: GBAUD 4800 Determines the GPS port bit-rate. 4800 for 4800 bps. 9600 for 9600 bps. Refer also to chapter 5-3-1. 4800 is recommended for NMEA compatible GPS units, 9600 for SONY GPS. Remember that this command sets bit-rate only, and is not related to the firmware of the device. The firmware checks SONY/NMEA GPS data by processing the contents of the receiving data.
data contained in the string will be automatically placed in the LTEXT buffer. If the GPSTEXT content is one of those below and does not match with the initial part of the data, it restructures the sentence and automatically updates the LTEXT content based on previously received GPS data. In other words, the feature offers the conversion of the GPS data. Understandable sentence Restructurable sentence $GPGGA $GPGGA $GPRMC $GPRMC $GPVTG $GPVTG $GPZDA $GPZDA SONY $PNTS SMATC 5-6-8 NTSGRP command Abbrev.
As mentioned in 2-1, the operational mode is usually “connect mode”. The “cmd:” prompt appears when it is in the command mode. If it does not appear, use CR or return or Enter key to display it on the screen. 6-2 Converse mode As briefly mentioned in 2-1, this is the mode to send typed data as a packet. By using the CONVERSE or the K command from the command mode, the TNC switches to the Converse mode. The TNC also enters the converse mode when you connect from your station to another station.
CMDTIME, press the C key 3 times with the Ctrl key pressed. 6-3-2 TRFLOW command Abbrev. TRF default OFF range ON/OFF example TRF OFF When ON, activates the software-flow function for the modem to host communication in the transparent mode. ON: Software-flow is activated. In this mode, the control codes for the soft-flow won’t be forwarded correctly, so it becomes “imperfect transparent mode”. The TNC responds to software flow control from the terminal. OFF: Soft-flow is not activated.
virtually any combination of characters can be passed by the software in use, protocols dictate that it must be very difficult to exit the KISS mode, once it has been activated. If you find the TNC in KISS mode and you wish to exit, you may use the TCP/IP command found in most KISS software or you may try sending a special sequence from your keyboard: 1. Press and hold the ALT key. Enter the numbers 192 from the numerical keypad NOT THE TOP OF THE KEYBOARD. Then release the ALT key. 2.
feature: Use this command to manually transmit HDCL-ID. This command works only when HID command is ON. This command will become invalid when the station is not used as a repeater after ID is sent. 8-2 Concept of UI digipeat This is to relay UI frames that match certain conditions. The APRS system in North America uses a network that is constructed with UI digipeats explained herein, in order to cover a large area with a single VHF frequency. It specifies means to relay and reduce useless relays.
8-3-3 UIDIGI command Abbrev. UI default OFF(empty) range ON/OFF call1[,call2[,call3[,call4]]] example UI ON WIDE, TRACE, RELAY UI OFF % (to empty “Call”) The UIDIGI relay won’t work when this parameter is set OFF, or the callsign area of the parameter is empty. If you wish to clear the callsigns, enter Call1 as %, Call2 % etc. When set to ON and callsigns are entered, then the frames that match all of following conditions will be relayed. When it is relayed, the frame will be processed as below.
is only to reduce Y value by 1. Example: In case of UIFLOOD WIDE, NOID MYCALL W1AAA W1BBB>GPS,WIDE4-4:Frame 1 -> W1BBB>GPS,WIDE4-3:Frame1 W1BBB>GPS,W1CCC*,WIDE4-3:Frame2 -> W1BBB>GPS,W1CCC*,WIDE4-2:Frame2 W1BBB>GPS,W1CCC*WIDE4-1:Frame 3 -> W1BBB>GPS,W1CCC*,WIDE4:Frame3 (Note that Y=SSID changes 1 to 0) W1BBB>GPS,W1CCC*,WIDE4:Frame4 -> This in not Name X-Y parameter (Y is 0) thus wont be relayed in UNFLOOD command. W1BBB>GPS,WIDE:Frame5 -> Same reason as above, no relay.
W1BBB>GPS,W1CCC*,TRACE4-3:Frame2 W1BBB>GPS,W1CCC,W1AAA*,TRACE4-2:Frame2-> W1BBB>GPS,W1CCC,W1DDD,W1EEE*,TRACE4-1:Frame3 W1BBB>GPS,W1CCC,W1DDD,W1EEE,W1AAA*,TRACE4;Frame3 W1BBB>GPS,W1CCC*,TRACE4:Frame4 -> This in not Name X-Y parameter (Y is 0) thus wont be relayed in UNTRACE command. W1BBB>GPS,TRACE:Frame5 -> Same reason as above, no relay. W1BBB>GPS,TRACE4-4:Frame6 -> This does not match Name, so no relay. 8-3-6 UISSID command Abbrev.
No unrelayed station in the relay route Relay modification process Sender’s SSID is replaced with 0 MYCALL setting callsign is inserted at the end of the relayed station list.
8-3-8 SPATH command Abbrev. SPATH default empty range 7 callsigns example SPATH W1YYY,W1ZZZ SPATH % (empty) In the UISSID command, if the sender’s callsign SSID is 9 or 13, it sets the relay route to be added to the relay station list. If SSID is in excess of 8, station won’t be added. Even if SPATH is empty, the relay with UISSID takes place, but without adding the relay route. Enter % to intentionally clear the value. 8-3-9 EPATH command Abbrev.
example STREAMD ON When a received packet contains stream-change code, this parameter determines whether or not to output both codes. When ON is selected the codes are both displayed. This enables you to identify which is the received code and which is the one received from other stream’s packet. OFF disables this function and the code won’t be displayed for both. 9-1-4 LCSTREAM command Abbrev.
connection. 10-1-4 ROUTE command Abbrev. ROU default ON range ON/OFF example ROU OFF When a Forwarded message is received from a forwarding BBS, this command determines if the routing information is saved or not. If ON, the route information is saved. OFF discards the information. 10-1-5 OVERKILL command Abbrev. OVE default 0 range 0-255 example OVE 10 This command will delete old messages stored in the memory automatically.
10-2-4 READ command Abbrev. R default None range n1,n2… example R 2 This command allows you to read the specified message in the MB. To read multiple messages, use comma as a separation. 10-2-5 WRITE command Abbrev. W default None range call example W W1BBB (to specify the destination) W (for open message) This command is for posting a message in the MB. When this command is input, “Subject:” appears, where you can write a message title, up to 30 characters for lower case, 15 for upper case.
When the message is finished, enter [CR][Ctrl-Z][CR] or [CR]/EX[CR]. If the writer exceeds the amount of available memory while composing a message, the WRITE function terminates and the message is deleted. 10-4-2 B command (BYE) Abbrev. None default None range None example B The connection to MB will be terminated when a user sends B (as in “BYE”). 10-4-3 F command (FILE) Abbrev. None default None range None example F To display the latest 20 messages, send F. 10-4-4 M command (MY MESSAGES) Abbrev.
11 Miscellaneous commands The followings are miscellaneous commands: Restart and Reset commands Display commands Display setting according to the terminal software 11-1 Restart and Reset 11-1-1 RESTART command Abbrev. RESTART default : none parameter: none Example: RESTART This will restart the TNC. If memories are stored, it initializes according to the stored data. This is used mainly to set parameters such as AWLEN and PARITY which is available only when the TNC is initialized.
11-3-3 DAYSTAMP Abbrev. DAYS default: OFF range ON/OFF example DAYS ON In converse mode, typing T with Ctrl pressed sends time data. By turning this command ON, the date information is transmitted. OFF disables the function. 11-4 RAM check command 11-4-1 RAMTEST command Abbrev. RAMTEST default: None range None example RAMTEST The RAMSET command clears the RAM, then checks and displays available memory capacity and error address. To exit, turn off the power.
