NOTE:
Caution should be exercised when using the INIT command on radios in a sys-
tem employing the Store-and-Forward feature. Settings relating to the use of
Extension services will be lost and will need to be re-entered. Inventory and
record the settings for XADDR, XPRI and XMAP
before using the INIT com-
mand.
SPECIAL NOTE:
Installing firmware of Revision 2.0 or later into a radio with Revi-
sions 1.x firmware will preserve the radio’s compatibility with oth-
er radios running Revision 1.x firmware. If updating the radio’s
firmware is part of a system-wide upgrade, the last step should
be to use the INIT command at the Master station. Use of the
INIT command causes the changes shown in
Table 10 on
Page 33 to be applied
HREV
Shows the Hardware revision of the radio.
KEY
Enables the transmitter. (Radio must be in Setup mode.) See also
DKEY
command.
MODE [M, R, X]
The
MODE
command sets or displays the operating mode of the radio. A
master radio is set by
MODE M
; a remote set by
MODE R
, and an Extension is
set by
MODE X
.
All units default to remotes; other modes must be specifically programmed
with the
MODE
command.
If
MODE X
is used, the
MODE X
radio should be programmed with an
Extended Address (
XADDR
). Units that need to hear this
MODE X
radio must
be programmed with an appropriate
XPRI
and/or
XMAP
value.
OWM [xxxxx]
The
OWM
command sets or displays an optional owner’s message, such as the
system name. The entry can contain up to 30 characters.
OWN [xxxxx]
The
OWN
command sets or displays an optional owner’s name, such as the
site name. The entry can contain up to 30 characters.
PORT [RS232, RS485]
Select or identify the current data port (
DATA
connector) interface signaling
mode:
RS232
or
RS485
. This is the port though which the payload data will
pass. Pin descriptions for EIA-232 are on Page 55 and EIA-485 can be found
on Page 56 .
