The pull-out terminal strip on the DigiBus side is mar-
ked as follows.
4. HARDWARE CONFIGURATION
Throughout this manual, component locations are described with
the interface positioned with the CN1 terminal strip at the bottom
left.
4.1. SIGNALLING (Led)
The green LED located under the DIP switch at the top left fun-
ctions as follows:
1. The LED flashes rapidly when a reset is being performed,
when the unit is switched on for the very first time, and follo-
wing the reset procedure described in section 3.
2. The LED flashes slowly when the interface is inactive.
3. The LED remains lit when the interface is active or busy with
a call.
4.2. BUS TERMINATION
Connector CN2 is located at the bottom right of the interface, to
the right of the CN5 terminal strip. Fit a jumper over any of the
three positions A-B-C to terminate the video signal on the ELVOX
TWO-WIRE bus. Try the jumper in all positions to find the one
that gives the best video quality.
4.3. VIDEO TERMINATION
When jumper CN7 is fitted, it provides a 75 Ohm termination for
the video signal on the DigiBus side.
4.4. IDENTITY ASSIGNMENT
Device identity is assigned on DIP switch S1 at the top left of
the interface. Only identities between 2 and 15 can be assigned.

2. ELECTRICAL INSTALLATION
The interface connects to the ELVOX TWO-WIRE system via the
CN1 terminal strip on the bottom left of the unit.
3. RESETTING
Proceed as follows if you ever need to restore the factory default
settings.
1. Press and hold the RES button at the top left of the unit.
2. Press and hold the CLR button at the top left of the unit next
