Via the SX Tool
The “Output Hold/Reset on Communication Failure” flag is set at Bit X2
of Item XTS (RI.69).
X2 = 0 Output reset upon communication failure
X2 = 1 Output hold upon communication failure
When communication fails for the period set in this Item, the XT-9100
goes into “communication failure” state, indicated by a blinking power
LED on the front of the module. The default value is 60 seconds.

First configure an XT Module. Select XTn, then Analog or Digital. Then
select the just configured XTn, XTn, and Data. At the “Comm. timeout
(sec)” field, enter the value in seconds.
Via the SX Tool
The “Maximum Time Between Communications” (in seconds) is entered
at Item MTBC (RI.86).
The operational mode of the XT-9100 can be seen at Item OPMO (RI.01)
with following status bits:
X8 = 1 PWR Power Failure. This bit is set when a XT is
powered up or when there is a serial interface
communication failure.
The setting in Item XTS (RI.69) Bit X2 (“Output Hold/Reset on
Communication Failure” flag) is repeated in Item OPMO (RI.01) Bit X7
so that it can be read by the DX-9100 or any other monitoring system.
Via the GX Tool
In order to download the XT-9100 devices it is necessary to enter the
XT addresses. These addresses will also be loaded into the DX-9100.
When performing a download through a DX-9100 Controller, the
controller only downloads the addresses of its own XT set. The
XT address is not stored in the XT-9100 but must be set on the address
switches on the module.
First configure an XT Module. Select XTn, then Analog or Digital. Then
select the just configured XTn, XTn, and Data. At the “Hardware
Address” field, enter the address (1-255) of the XT-9100 module.
