5.4.5 Troubleshooting, GOES Transmitter (part #TX312) 
If a problem with the GOES transmitter (part #TX312) is suspected, the TX312 
may be checked by measuring the +12 V and Ground terminal on the CR1000 
PC-board wiring panel. Acceptable readings are +11 VDC to +14 VDC. 
Check the SC12 cable connection between the CR1000 wiring panel and the 
TX312. Press the TX312 diagnostic button to query the state of the 
transmitter. If problems persist, try a substitute. Obtain a Return Material 
Authorization (RMA) number before returning this equipment to Campbell 
Scientific for repair. 
5.5 Voice Radio Interface (part #VSP3) (Optional) 
5.5.1 General Description, Voice Radio Interface (part #VSP3) 
The DACOM Voice Radio Interface (part #VSP3) shown in Figure 5.5-1 is 
mounted inside the RAWS environmental enclosure. The VSP3 converts data 
into voice messages that can be transmitted via UHF or VHF transceiver. The 
VSP3 Vosponder uses phonetic native text string to speech conversion, which 
provides for an unlimited vocabulary. The Vosponder communicates with a 
datalogger using the SDI-12 protocol. The VSP3 Vosponder can be integrated 
into an existing UHF/VHF radio network. A minimum of two radios with 
matching frequencies is required. The VSP3 ships preprogrammed with a 
voice image file for the fire weather market. 
A minimum of two radios with matching frequencies is required 
to transmit voice messages. To activate the voice file, hold down 
the radio microphone button and press 9 on the radio keypad.  
Radios can be purchased from Campbell Scientific.
