 XCVR Status
Displays the status of the transceiver.
 Tx Timeout
A request for a remote unit to transmit causes the unti to transmit on the programmed transmit frequency until
the Tx Timeout Timer expires. Program the Tx Timeout Timer in the Setup Modem/Radio Parameters/Radio Tab.
 Progress
The Progress panel shows the progress of the Get Diags request.
 Tx Mode
Allows the user to select different transmit modes when the unit is told to transmit:
o Tone: the unit will transmit a 1200 Hz tone.
o Mod Balance: the unit will transmit a 100 Hz square wave.
o Random Data: the unit will transmit random data.
o No Modulation: the unit will transmit with no modulation.
 External I/O 1 (Pin 3 - Green Wire):
When the I/O 1 connection of the Power - I/O Connector is configured as a Digital Output, External I/O displays the
state of the open-collector transistor (ON-Grounded/OFF-Open). If configured as an Analog Input, External I/O
displays the voltage on the connector (in volts). Programming of External I/O 1 is performed in the Setup
Modem/Radio Parameters screen.
 External I/O 2 (Pin 4 - White Wire):
When the I/O 2 connection of the Power - I/O Connector is configured as a Digital Output, this displays the state of
the open-collector transistor (ON - Grounded / OFF - Open). If configured as Analog Input, External I/O 2 displays
the voltage on the connector (in volts). Programming of the External I/O 2 is performed in the Setup Modem/Radio
Parameters screen.
 External I/O 1 ON (Grounded):
When the I/O 1 connection of the Power - I/O Connector is configured as a Digital Output, this checkbox is enabled
to allow for the change of state of the open-collector output of Pin 3. Clicking on this check box causes immediate
action to change the state of the output. This is true for local or a selected remote ID.
 External I/O 2 ON (Grounded):
When the I/O 2 connection of the Power - I/O Connector is configured as a Digital Output, this checkbox is enabled
to allow for the change of state of the open-collector output on Pin 4. Clicking on this check box causes immediate
action to change the state of the output. This is true for local or a selected remote ID.
Modem Select
 Local ID
Allows the user to send commands to the local unit (the unit interfaced to the computer). The Short ID for this unit
is shown.
