Received Data Audio
Level
RXLEVEL [–20 to +3]
The RXLEVEL and TXLEVEL (Page 59) commands control the audio level
settings when the radio is operating in analog mode. When used alone,
the RXLEVEL command displays the receive level in dBm. Entering the
RXLEVEL command followed by a number from –20 to +3 resets the
audio level in dBm.
NOTE: The RXLEVEL and TXLEVEL commands are only available on the
“A”/analog model radios.
Receiver Muting RXMUTE [ON/OFF/Time in msec]
Use this command to set or display the radio’s receive (RX) muting
status. Receive muting might be required when you configure the radio
as a full-duplex polling remote communicating through a repeater. It
prevents the radio from hearing its own transmissions (“echoes”) from
the repeater, which might cause software application errors.
Entering the RXMUTE command without a parameter shows whether the
muting feature is ON (enabled) or OFF (disabled). Entering the RXMUTE
command followed by ON enables muting; entering OFF disables it.
After issuing the RXMUTE ON command, you can specify a receive
muting time. Use the RXMUTE nn command, where nn is a time in milli-
seconds. This causes the receive muting feature to assert for nn millisec-
onds following the end of a transmission.
Receive Data
Attenuator
RXPAD [ON/OFF]
This command enables or disables the receive attenuator for the receive
audio level on radios operating in the analog mode. Entering the RXPAD
command without a parameter shows whether the attenuator is
ON
(enabled) or
OFF (disabled). Entering the RXPAD command followed by
ON enables the receive attenuator; entering OFF disables it.
Receiver
Timeout-Timer
RXTOT [NONE, 1-1440]
The
RXTOT command selects or displays the receive timeout timer value
in minutes if the receiver fails in a way that generates no other alarms
(for example, if data is not detected within the specified time). This
timer triggers an alarm (event 12) and forces a switch-over to the
standby transceiver board.
