d. Set the data interface parameters to match the connected data
device—The default setting is 4800 baud, 8 data bits, no parity, 1
stop bit. If your data equipment requires a different setting, use
the
BAUD xxxxx abc
baud rate (1200, 2400, 4800, 9600, 19200, or 38400 bps) and
indicates the control bits as follows:
= Data bits (7 or 8)
a
= Parity (N for None, O for Odd, E for Even)
b
= Stop bits (1 or 2)
c
Using this scheme, a sample entry for the
mand would look like this:
using a five-character baud rate would appear as follows:

Press . After setting the data parameters,

will be displayed.
OK
NOTE: 7N1, 8O2, and 8E2 are invalid communication settings and are
not supported by the transceiver.
e. Record the Mode, Network Address, and Baud Rate settings on
a label and affix it to the transceiver cover.
6. Repeat the above steps for each transceiver in the network.
This completes the basic installation of the transceiver. Section 5.1, Ini-
tial Start-up (beginning on Page 26), contains steps for evaluating radio
performance.

4.2 Peer-to-Peer Systems

Peer-to-peer systems allow remote radios to communicate with each
other as well as with the master station. The paragraphs below describe
two types of peer-to-peer systems—simplex and repeater assisted.

Simplex Peer-to-Peer

A simplex peer-to-peer system is one in which all radios use the same
transmit and receive frequencies. This is also known as single-frequency
operation. A simplex arrangement is the simplest configuration for
peer-to-peer systems, but it usually has limited transmission range
because of the need for all stations to use omnidirectional antennas. (If
range is a concern, see "Peer-to-Peer with Repeater Assistance" on page
20.)
With a simplex peer-to-peer system, there are three key items to
remember:
To program a system for simplex operation, the master radio must
be set to
