Default
Sets the power source for the radio or modem.
Off - no power supply.
Off
Battery - power supply from the battery via a relay.
Controlled supply - a voltage controlled supply is provided.
6,000 mV
Voltage when using controlled supply.
Enter the average current the installed radio will consume. This is
required for reliable battery management when running from auxiliary
100 mA
power supply.
This value is an estimate of: the receive current plus the transmit current
x transmit duty cycle. Required accuracy is +/- 50%.
This is a time-out setting in multiples of 10 minutes. If a protocol
message has not been received for this time, then the radio will be
2,550
powered off for 10 seconds and then powered on again. The purpose is
minutes
to restart the radio periodically if there is no SCADA activity just in case
the radio is the problem. Range is 1 to 255 giving 10 to 2,550 minutes.
Default
Signals can be RS232 or logic level when logic level, voltage and Tx/Rx
RS232
signal polarity can be configured.
5,000
This sets the radio signal voltage when using logic-level serial interface.
Off
To enable PTT with pre-transmit and post-transmit times as below.
0
PTT output will be turned on for this time period before transmitting.
PTT output will remain on for this time period after transmitting has
0
stopped.
Normal TTL Tx polarity will have a logic high when idle. Start, stop and
Normal
data bits will have standard polarity. Inverted TTL Tx polarity will have a
logic low when idle. Start, stop and data bits will be inverted also.
Normal TTL Rx polarity will have a logic high when idle. Start, stop and
Normal
data bits will have standard polarity. Inverted TTL Rx polarity will have a
logic low when idle. Start, stop and data bits will be inverted also.
115,200
When enabled, RCU serial transmission will only occur when the CTS
Disabled
input pin is asserted. When disabled, the CTS input pin is ignored.
When enabled, the RCU RTS output pin will be de-asserted in request to
Disabled
stop receiving serial data (buffer full, unable to process more incoming
data). When disabled, the RTS output pin is de-asserted.
