Data Devices. Numerous data devices can be connected to outstations A and B. Each have technical

bulletins describing their interoperability and connectivity to SINCGARS. Should a data device be used, the

data rate should be set the same at all the RT-1523s.

System Troubleshooting Procedures. These steps will assist you in isolating faulty system components when

you have a problem communicating in a net using data transmission. These procedures assume that the net

and secure FH voice communication has been established. If you are unable to communicate using data

transmission, do the following troubleshooting steps in the order provided.

CHECK LOCAL RADIO. Use the data on the FH voice net to determine that the radio net is operating.

CHECK WITH OTHER NET MEMBERS. Do you have data communication with some stations but

not others? The other station may be out of range, temporarily off the air, or has not checked into the

net. If data communication can be established with another station, your system is probably O.K. and

the problem may be at the distant net station.

If you are attempting to use the same Net ID or Single Channel Frequency, Relay C, E and Outstation

A must be physically separated from Relay D, F and Outstation B by a minimum of 50 to 75 miles.

CHECK SYSTEM CONFIGURATION. Verify proper cabling, initialization and subscriber parameters,

radio set and AN/PSC-3 switch settings, etc. Of special concern is the squelch setting on the RT-1402.

NOTIFY MAINTENANCE. If the problem cannot be isolated, notify unit maintenance personnel and

inform your NCS of your communication problem.
