BT [.x]
Relative TX Bandwidth
• Valid options are .3 and .5
• Leading zero (Ø) not permitted
NOTE: Must complement BAUD and BW values.
(See Table 1 on Page 8.)
BW [xx.x]
Channel Bandwidth
• Options: 25 and 12.5 kHz
NOTE: Must complement BT and BW values.
(See Table 1 on Page 8.)
CLK [xx]
Clock Output Pin
Selects which serial clock line to use for transmit operation.
• Options: TX and RX
• TX = Pin 8/TXC
• RX = Pin 6/RXC
CDR [–xxx]
Receiver Carrier Detect Threshold
• Inhibits the receiver from processing an incoming signal
unless it is above the setting’s level.
• Range: –50 to –120
NOTE: A setting of -120 removes any limitation on signal
detection.
CDT [–xxx]
Transmit Carrier Detect Threshold
Inhibits the transmitter from operating in the presence of a
strong on-channel signal until the signal level is below the
setting level.
• Range: –50 to –120
NOTES:
• –50 will effectively allow transmissions anytime
• –120 will effectively prohibit transmissions.
• Minus sign (–) required for data entry

Data Scrambler/Descrambler ON/OFF
Options: ON or OFF
SREV [xxx]
Software Revision of installed firmware
SER
Serial Number of the radio
RSSI

• Displays the current received RF signal level
• One measurement per request by command
• Reading is accurate to within 3 dB from –100 dBm to –60
dBm
NOTE: A continuous RSSI signal available during receive
state on the DATA INTERFACE connector (J100-Pin12).
