MDS 05-3438A01, Rev. F MDS 4790/9790 Series I/O Guide 73
Unit Address The unit address identifies the radio as a unique unit within a network managed by
MDS’ InSite™ NMS software or similar program. This address is independent of
the Multi-Drop Address (above) and is needed only for local and over-the-air
diagnostics and control services of this unit through an NMS program such as
InSite.
The default unit address is the last four digits of the radio’s serial number.
User-programmable unit addresses can range 10000...65000 (addresses in the 0
to 9999 range are reserved for factory use). Once you change the default unit
address, it cannot be reprogrammed.
NOTE: The Unit Address operates independently from the Multi-Drop Address.
(See “Multiple-Drop Address” above for details).
Standby
Equipment
Use this screen to notify the monitoring processor of the presence of a second
radio assembly within the chassis so that it can switch to the alternate radio unit if
a failure of the primary radio assembly occurs.
To identify the available hardware, press ENTER, then use the up/down arrow
buttons to select:
defined, if the chassis is equipped with two radio assemblies
not defined, if the chassis equipped with only one radio assembly
The unit does not know if there are one or two radio transceiver assemblies
installed. Make sure you know what hardware is installed before making a change.
Battery Backup Use the Battery Backup screen to set or show the monitoring of the internal
back-up battery voltage (condition) and if you want the radio to send an alarm when
the radio is operating from the internal back-up battery or the voltage falls below
13 Vdc.
Battery Backup “not defined” means the battery is not installed or you do not desire
to monitor its condition. “defined” indicates that monitoring is enabled and an alarm
message will be created when the battery voltage is less than 13 Vdc.
To set the radio to monitor the internal back-up battery, press ENTER, then use the
up/down arrow buttons to select “defined”. Press ENTER again to make the
change. To set the radio to ignore the battery condition, press ENTER, then use
the up/down arrow buttons to select “not defined”. Press ENTER again to make the
change.
Key On Data Use this screen to set or show the radio’s keying mode (key-on-data, or
key-on-RTS). In key-on-data mode, the radio automatically keys itself whenever
input data arrives on the DB-25 port. In key-on-RTS mode, the radio will only key
in response to an RTS or PTT signal.
To set the radio to key-on-data mode, press ENTER, then use the up/down arrow
buttons to select ENABLE. Press ENTER again to make the change. To set the
radio to key-on-RTS mode, press ENTER, then use the up/down arrow buttons to
select DISABLE. Press ENTER again to make the change.
