OTHER COMMANDS (MASTER UNIT ONLY)
Those commands are not indispensable, see paragraph.1.2 GLOBAL EMERGENCY ACTIVATION.
ITL BGM can be used to connect BGM signal in alternative to the BGM connector available on the main board
(see paragraph 2.1 BGM JUMPER) – only on the MASTER unit.
On the IT 3010 board of the MASTER Unit with commands ITL EVAC/ITL RESET it is possible to activate and
reset globally the emergency message in all the DXT 3000 units connected to the system (see paragraph 1.2).
4.3. IE 3008
If IT 3010 is not installed the INTERLINK Bus must be connected to the IE 3008 board. The connections are the
same as previously described for IT 3010 board. The only difference is in the use of the screw terminal instead
of the RJ 45 connectors. As previously stated, it is recommended the use of IT 3010 board when INTERLINK
BUS length is greater than 10metres.
The correspondence to match between the CJ 428 CAT twisted pairs and the screw terminal on the IE 3008
board is reported below.
