Transmit Data Audio
Gain Enhancement
TXGAIN [ON/OFF]
This command enables or disables the transmit audio boost for the
transmit audio level in radios operating in analog mode using J2: 4-WIRE
AUDIO INTERFACE
. Entering the TXGAIN command without a parameter
shows whether the audio boost is ON (enabled) or OFF (disabled).
Entering the TXGAIN command followed by ON enables audio boost;
entering OFF disables it.
NOTE: The RXLEVEL and TXLEVEL commands are only available on the
“A”/analog model radios.
Transmit Data Audio
Level
TXLEVEL [–20 to +3, AUTO]
Use the TXLEVEL and RXLEVEL (Page 53) commands to control the audio
level settings when using the analog mode for equipment connected to
the 4-WIRE AUDIO CONNECTOR (J2). When used alone, the TXLEVEL
command displays the transmit level in dBm. Entering the TXLEVEL
command followed by a number from –20 to +3 (inclusive) resets the
audio level in dBm. Entering the TXLEVEL command followed by AUTO
causes the radio to set the transmit level automatically. The default set-
ting is AUTO.
Evaluate system performance in the AUTO mode. In most cases, this
setting provides satisfactory performance. If it does not, evaluate the
BER at the other settings.
Unit Diagnostic
Address
UNIT [10000–65000]
This command sets or displays the radio’s unit address, which uniquely
identifies a single radio within a network in support of a network man-
agement system (NMS) program, such as MDS’ InSite™.
The default unit address is the last four digits of the radio’s serial
number. User-programmable unit addresses can range 10000...65000
(addresses in the 0...9999 range are reserved for use by the factory).
Once you change the default unit address, it cannot be reprogrammed.
NOTE: The Unit Address operates independently from the Multi-Drop
Address (“Multiple-Drop Address” on Page 48).
