IP
The
IP
(increment power) command is a local maintenance command
that increases the transmit power by 1% of the adjustable range. This is
a temporary setting until the
RMST
command is used to store the com-
mand.
KEY
This command activates the transmitter. See also the
DKEY
command.
LBC [xxxx]
This command programs or displays the loopback code of a radio. The
loopback code provides a means to uniquely identify a single radio
within a network. It is used primarily for diagnostic purposes, and is
intended to be identical to the loopback code command of older trans-
ceivers.
By default it is set to the last 4 digits of the serial number. See
SER
com-
mand. Loopback codes can range from 0...9999.
MODEL
This command displays the radio’s model number code. Refer to
Figure 4 on page 4 for an explanation of the model number characters.
MODEM [NONE, BELL, 4800B, 9600B]
This command sets the signal type and modulation mode of the radio.
The radio may not have all options available. Contact MDS if you need
a modem that is currently unavailable on the radio.
A choice of
NONE
selects no modem and the radio operates as an analog
transceiver using Transmit Audio Input (Pin-9) and Receive Audio
Output (Pin-11). Refer to Table 5 for
DATA INTERFACE
connector
pinouts.
A choice of
BELL
selects a Bell 202T type of analog modem that is com-
patible with the MDS 1000µ, MDS 2310, or the MDS 4310 series of
radio products equipped with a 1200 bps Bell 202T modem. All baud
rates up to 1200 are automatically supported as data is received. The
BAUD
command setting is irrelevant.
The choice of
4800B
selects a 4800 bps modem modulation compatible
with the MDS 1000µ, MDS 2310, or the MDS 4310 series of radio prod-
ucts equipped with a 4800 bps modem. All baud rates up to 4800 are
automatically supported as data is received. The
BAUD
command setting
is irrelevant.
The choice of
9600B
selects a 9600 bps modem modulation compatible
with the MDS 1000µ, MDS 2310, or the MDS 4310 series of radio prod-
