6.2
Adding a Line Card
The ViLX-228 Master Station is supplied with at least one number Line Card. There are 2 lines per
Line Card.
Before adding a Line Card, ensure that the ViLX-228 Master Station is not powered. If the ViLX-228
Master Station is powered, then power down the ViLX-228 Master Station (see 5.10).
To fit the Line Card:
1.
Place Line Card in the next available space on the Exchange PCB and secure using the supplied
screw.
2.
Remove the line terminal and connect the field wiring.
3.
Push the terminal into the correct position on the Line Card.
4.
Set the dipswitch on the Display PCB (see 6.1) to enable Line Card monitoring.
Once the Line Card is securely fitted, power up the ViLX-228 Master Station (see 5.9).
6.3
Removing a Line card
Before removing a Line Card, ensure that the ViLX-228 Master Station is not powered. If the ViLX-228
Master Station is powered, then power down the ViLX-228 Master Station (see 5.10).
To remove the Line Card:
1.
Remove all line terminals from the Line Card that is to be removed.
2.
Remove the securing screw.
3.
Remove the Line Card from Exchange PCB.
4.
Set the dipswitch on the Display PCB (see 6.1) to disable Line Card monitoring.
Once the Line Card has been removed, the ViLX-228 Master Station may be powered (see 5.9).
6.4
Adding a ViLX-228 Repeater Station
The ViLX-228 Master Station has in-built networking which means a single additional ViLX-228 Master
Station can be added. This additional ViLX-228 Master Station is designated as the ViLX-228 Repeater
Station. The ViLX-228 Repeater Station must be wired as a ring to comply with BS5839pt9:2011
The 4 Line Cards can be distributed between the ViLX-228 Master Station and the ViLX-228 Repeater
Station in any combination, as long as the Line Cards do not occupy the same position on the Exchange
PCB in both the ViLX-228 Master Station and the ViLX-228 Repeater Station, i.e. if a Line Card is in
position 1 (Lines 1&2) on the ViLX-228 Master Station, then no Line Card can be placed into position 1
(Lines 1&2) on the ViLX-228 Repeater Station.
Network connections used are Network Out and Network In, with Network In on one Station wired to
Network Out on the other Station (A to A, B to B, C to C, and D to D).
The default network address setting for the ViLX-228 Master Station is 1. When adding a ViLX-228
Repeater Station, it must share the same address as the ViLX-228 Master Station.
