Audio - GE MDS Master Station Technical Manual

RSSI out 0-Point – When RSSI out is enabled, this is the RSSI level (in dBm) that will
•
result in an output voltage of 0 mV
RSSI out mV per dBm – When RSSI out is enabled, this is the voltage (in mV) that will
•
be produced for each dBm of signal strength above the level specified in rssi-out-0-point.
E.g. Given a zero point of -120dBm, and a mv-per-dbm value of 50mV, an RSSI of
-84dBm would result in an output of 1800mV.

Audio

Audio settings are only available for configuration when the radio is configured to oper-
ate in x710 compatibility mode.
Audio Enabled – If enabled, the radio's transmit functionality will switch to analog
•
whenever PTT is asserted.
Rx Level – Receive Audio Output Level to Modem (dBm). Received signal at the peak
•
deviation will be scaled to the specified value. Valid range is (-20
Tx Level Auto – Automatically adjust transmit audio input level from Modem.
•
Tx Level – Transmit audio input level from Modem (dBm). A transmit input signal of the
•
specified value will translate into the specified peak deviation for transmit. Valid range is
(-20 0).
Emphasis – When enabled, pre-emphasis is applied on the transmitter and de-emphasis is
•
applied on the receiver. This setting is typically used in operation with voice radios.
Squelch – When set to auto, the transceiver will use its internal squelch to enable
•
transmission of audio signals. When set to bypassed, the transceiver will transmit all audio
signals regardless of level.
Vox Enabled – Enables or disables the integrated VOX threshold.
•
Vox Threshold – The audio interface on the Master Station incorporates an integrated
•
VOX circuit to sample the voltage produced by a connected audio device. When the
voltage exceeds a user-defined threshold, Push to Talk (PTT) is activated, resulting in the
