General Description
Installation and Operation Manual
Testing and Alignment
The has a calibrate function and an LED bar graph to aid in setting receive and
transmit levels. It also incorporates a comprehensive built in test routine to test every
circuit of the unit. The internal monitor speaker allows the user to hear all incoming and
outgoing transmissions to aid in system setup and troubleshooting.
Audio Inputs
The has two line level inputs, each with its own PTT line, a local mic input with
PTT, and an XLR balanced input incorporating a VOX PTT for balanced or distant mics.
The XLR input can provide a ghost supply for amplified mics. Use amplified or non-
amplified microphone.
Serial Ports
The has two serial ports. Use COM1 for interfacing with Commander Software
or Encoder Software. Use COM2 to send printer messages or receive text messages to a
display or peripheral device. Also, use COM2 to interface with Commander Software,
Encoder Software, or an external radio modem.
Relay Outputs
The has three Relay Outputs that you can program to activate when an
activation button is pressed. Each relay has an off time and an on time. Alternatively,
configure each relay to activate when the unit has not been polled in 30 minutes, when an
RTU reports a fault, or when PTT or Carrier Detect are active.
Activation Buttons
Located on the front panel of the are twenty-four programmable activation
buttons that activates functions one through twenty-four.
Configure each activation function for Auto Prompt Send or Auto Send. Auto Prompt
Send prompts you to press the SEND button after an activation button has been pressed
before initiating the activation. Auto Send sends the code out when you press the
activation button without being prompted to press SEND. The same method is used with
Auto Prompt Send Auto Report and Auto Send Auto Report modes, which include and
automated system wide poll after activation. You can print each activation and status
reports to a printer.
Remote Activation Inputs
Located on the back of the are twenty external activation inputs that can be
driven by a contact closure. These inputs are optically isolated and activate buttons
one through twenty. Debounce time for remote inputs is 250 ms. An input held closed
for extended time will not generate multiple activations. These twenty external (rear
mount) inputs are factory set to activate activation inputs one through twenty. Modify the
jumpers on the internal PCB to allow the inputs to be used for additional functions. For
example, use the remote inputs as inputs twenty-one through forty or forty-one through
sixty. See “Remote Activation Inputs Board Connectors” on page 18.
