TRANSCEIVER PROGRAMMING
To program and control the transceiver, use the radio’s RJ-11
DIAG
(Diagnostics) connector with a GE MDS Hand-Held Terminal (MDS
P/N 02-1501A01). This section contains a reference chart (
Table 9
) and
detailed descriptions for each user command.
NOTE:
In addition to HHT control, Windows-based software is avail-
able (MDS P/N 03-3156A01) to allow diagnostics and
programming using a personal computer. An installation
booklet and on-line instructions are included with the soft-
ware. Contact GE MDS for ordering information.
4.1 Hand-Held Terminal Connection & Startup
This section provides basic information for connecting and using the GE
MDS Hand-Held Terminal. For more information about the terminal,
refer to the instructions included with the HHT kit.
The steps below assume that the HHT is configured for use with the
transceiver (80 character screen display). If the HHT was previously
used with a different model transceiver, or if its default settings were
changed, refer to
Section 4.2, Hand-Held Terminal Setup
(
Page 16
) for
setup details.
Follow these steps to connect the HHT:
1. Connect the HHT’s coiled cord to the
DIAG
(
RJ-11
)
jack on the radio
as shown in
Figure 9
. This automatically places the radio into the
control and programming mode.
As an alternative, the
DATA INTERFACE
(DB-25) connector can be
used for programming instead of the
DIAG
jack. With this arrange-
ment, Pin 23 of the HHT cable must be grounded to enable the diag-
nostic channel (
Table 6 on Page 11
).
