1-3 EQUIPMENT DESCRIPTION The URC-200 (V2) VHF/UHF Transceiver is a lightweight, tactical, Line-Of-Sight (LOS) transceiver that provides AM and FM communication of nonsecure voice or data. It is suitable for manpack, vehicular, or fixed station applications. The transceiver can be used with other AM or FM transceivers operating in the same VHF and UHF frequency ranges. In the AM mode the VHF frequency range is 115 to 149.9950 MHz In the FM mode the VHF frequency range is 115 to 173.
The antenna is a 12-inch long, broadband, VHF/UHF vertically polarized antenna that is attached to the front panel antenna connector. The antenna connector is a BNC type connector, surrounded by a threaded sleeve. The antenna is screwed onto this sleeve. 1.5.3 BATTERY CASE - UBC-100 The battery case holds two batteries. Always use two of the same type battery when replacing batteries. Refer to Table 1-1 for available battery types and part numbers. Table 1-1.

Figure 2-2. Key-pad and Display Functions 2-3.1. NORMAL OPERATING MODE CONFIGURATION PROCEDURES The transceiver can be used for operation once it has been installed as described in Section 3. The transceiver is fully micro-processor-controlled from push button instructions selected at the front panel. The frequency is tuned either by selecting one of ten preset channels or by manually setting up the frequency on the LCD display.
2-3.1.1 Turning on the Unit Before performing the following steps, refer to Paragraph 2-2 for the location and functional description of the controls and indicators. 1. Make sure the transceiver set is connected for operation according to the installation instructions in Section 3. 2. Turn on the transceiver by turning the VOL control clockwise. 3. Set the VOL control for the desired volume (the SQ control must be in maximum counter clockwise position).
2-3.1.5 Select Meter Mode Pressing the [MODE] key and then the [PWR] key activates the METER MODE. When the transceiver is in the receive mode, the display becomes a signal strength meter in the form of a bargraph, indicating the relative strength of the incoming receive signal. The meter will indicate a single bar at approximately -115 dBm and be full scale at approximately +3 dBm.
2-3.2.2 Select Frequencies With a channel set-up as above, pressing the [FREQ] key (key-pad [1]) the transceiver will go into the "enter frequency" mode. The main display is blanked out except for the channel number (the number shown to the left the colon). The first digit of the desired frequency (1, 2, or 3) is pressed next and is displayed to the right of the colon. At this point, the transceiver will still be receiving on the same frequency as before.
2-3.2.4 Select Cipher Text/Plain Text Pressing the [PCV] key toggles between the plain-text and cipher-text (data) modes for the currently-displayed channel. The new value will take effect immediately when the [STO] key is pressed, as indicated by the annunciator. 2-3.2.5 Select Receive/Transmit Data Pressing the [R/T] key switches the display between the receive frequency and its operating data for the selected channel and the transmit frequency and data for that channel.
2-3.2.8 Select Transmit Power Levels 8 PWR Pressing the [PWR] key selects the transmit power levels for the transceiver. The power level annunciator will show the current setting. There are three power levels, LO, MED, and HI, available in the FM modulation mode and two power levels, LO and HI, when AM is selected. FM LO MED HI 2-3.3. SELECTING SPECIAL MODES The following paragraphs describe the procedures for special operating modes and functions of the transceiver.
2-3.3.2 Select Beacon Mode Pressing the [MODE] key and then the [BCN] key activates or de-activates the BEACON MODE. When the BEACON MODE is selected, the transceiver transmits a sweeping emergency audio signal on the selected channel frequency and in the selected modulation mode (AM or FM). The display alternately switches between the word "BEACON" and the selected channel information. No other operating functions are available when the BEACON is active.
2-5. OPERATING PROCEDURE 2.5.1 SITING The transceiver operates in the VHF and UHF frequency bands, these are Line-Of Sight (LOS) frequencies; therefore, siting of the transceiver greatly affects its operating range. The longest range is normally obtained when a direct LOS is maintained between the transceivers. Use of hilltop or tower locations will increase the LOS range. Location in valleys with intervening hills, behind buildings or in dense woods may reduce or prevent communications.
always starting in preset channel 0 at power up. (Reference: Paragraph 2-3.2.1 and Table 3-3, "P" code. 2-6.1.4 Storing Presets This command allows the user to change the stored information for the current preset channel. (Receive/transmit frequency, and selection of AM or FM. Excessive use of the Q command may result in defective channel data and/or the transceiver may always start in preset channel 0 at power up. (Reference: Paragraph 2-3.2.6 and Table 3-3, "Q" code. 2-6.2.
SECTION 3. INSTALLATION 3-1. GENERAL INFORMATION This section contains information necessary for preparing the URC-200 (V2) Transceiver for use. Included is information on installation of the battery, handset and antenna. Also provided are connector pin-outs, levels and impedances and computer interface information for remote control of the transceiver via a RS-232 interface. 3-2. ASSEMBLY AND PREPARATION FOR USE 3-2.1. CHECKING UNPACKED EQUIPMENT After unpacking it, check the equipment as follows: 1.
NOTE Lithium Battery Pre-Conditioning When using BA-5590/U lithium batteries, General Dynamics – C4 Systems recommends that the user consult MIL-B-49430 (ER), 'MIL-SPEC, Batteries, non-rechargeable, Lithium Sulfur Dioxide', and MIL-B-49430/3D (ER) 'MIL-SPEC, Batteries, nonrechargeable, Lithium Sulfur Dioxide BA-5590/U.' Particular attention should be paid to the paragraphs relating to voltage delay of the BA-5590/U. It is recommended that the batteries be changed in pairs.
CAUTION Several conditions must be observed when using the UVU-100 LOS antenna mounted on the transceiver's front panel, as serious damage to the transceiver may result if high RF power is allowed to leak into the interior of the transceiver directly from the antenna. 1. Transmit ONLY with the cover of the transceiver securely fastened in place. 2. Use ONLY vendor supplied power supplies, such as the RF shielded battery case (UBC-100) or power supply (UAC-100). 3.
3-3. REMOTE OPERATION The Remote Control Unit (RCU) shown in Figure 3-1 can either be a personal computer or it can be a Remote Terminal Unit (a handset, or a control head connected by a cable of up to 250 ft). As shown, the RCU is connected in a master/slave relationship to the transceiver and the RCU always initiates a given command. All commands are sent as a series of ASCII characters over the RS232 connection. RCU RADIO (MASTER) (SLAVE) Figure 3-1.
The data rate is 1200 bps 5%. The data code is serial 8-bit ASCII including no parity, one start bit and one stop bit, no flow control. The logic levels for the three-wire serial interface are as follows. Pin # Description IMPEDANCE LOGIC LEVEL S a A Remote Data Out Remote Data In Ground 470 6.8 k RS232 RS232 3-3.1.3 Data Exchange Protocol The RCU initiates all configuration commands and status inquiries to the transceiver using the RS-232 data communication protocol.

WARNING DO NOT THROW BATTERIES IN THE TRASH Dispose of all used batteries in accordance with all Federal, State and local laws and regulations. Lithium batteries may be used in the URC-200 (V2) Transceiver however lithium batteries contain hazardous materials. Improper handling, reverse-current operation or high environmental temperatures may cause internally generated heat, fire or toxic materials and gasses to be released from the battery.
CAUTION DO NOT attempt to change the operating frequency while the transmitter is keyed on. Although the radio set will not be damaged, the radiated frequency will be uncontrolled during tuning and can cause unnecessary interference to other radio systems. CAUTION DO NOT install the LOS antenna on the transceiver during testing in the transmit mode with (1) the cover removed or (2) the transceiver powered from an external power supply via test leads that are unshielded.
