CONNECTING TO THE CRU USING
STMON.
STMON is an MS-DOS PC communications utility that allows the status of an
AS4000 Subscriber Terminal to be displayed on a PC screen. It is intended to be used
as a commissioning tool and may also be used as an aid to troubleshooting.
New versions of the CRU require STMON Version J or later as the have an extended
information field to cater for the increased range of RF Frequencies used by the
AS4000 System. Version J is also compatible with older versions of the CRU
STEP PROCEDURE
Preliminary
1. STMON works by intercepting messages that are sent over the ST downlink
RS232 link to the Junction Box. From these messages STMON is able to display
the following data;
• ST channel code
• Downlink status
• Uplink status
• Downlink AGC level
• Downlink ‘soft error’ count
• Uplink Power Control level
• ST software status
In addition to displaying this data STMON is also able to log this information
to a file.
