Configuring the PKLR2400
Preliminary 36
7.2.4 End Character Definition
EEPROM Address: 3EH
Size: 1 bytes
Default: 0D
Range: 00-FF
This parameter is used only when the radio is operated in Serial Interface Mode 02 specified by
EEPROM address 4AH. Otherwise, this parameter is ignored by the system. The parameter specified by
the user will indicate the last character in a data packet. When this end character is seen by the radio, the
packet will be transmitted.
The packet length including the end character can not exceed 2Kbytes.
7.2.5 Fixed Packet Length High Byte/Low Byte
EEPROM Address: 43H/44H
Size: 1 byte each
Default: 01/00
Range: 00/01 to 07/FFH
This parameter is active only when the radio is in Serial Interface Modes 01 or 04 specified by
EEPROM address 4AH. This parameter is ignored in all other modes.
The fixed packet length can not
exceed 2Kbytes or it will not be received.
7.2.6 Serial Interface Modes
EEPROM Address: 4AH
Size: 1 bytes
Default: 03
Range: 01-04
There are four Serial Interface Modes for the OEM radio including one packet mode and three
transparent modes. All modes are differentiated by the definition of when data will be transmitted by the
radio.
Mode 01 specifies Transparent mode with fixed length packets and active timeout. Packets will be
transmitted over the RF interface when one of the following conditions occurs:
• The number of data bytes received over the interface is equal to the buffer specified by
the user in EEPROM address locations 43H and 44H.
• A byte gap larger the timeout specified by the user in EEPROM location 4DH occurs.
Mode 02 specifies Transparent mode with End Character. Packets will be transmitted over the RF
interface when the user-defined End Character is received by the radio over the interface. The End
Character is defined by the user at EEPROM location 3EH.
Mode 03 specifies API Mode. In this mode, the OEM has control of the radio command set
detailed in Section 6.2. Packets are buffered and transmitted at the direction of the OEM.
