3.1

CHOOSING A SUITABLE LOCATION

Choose a cool, dry location away from direct sunlight. A cold, air conditioned room will give
maximum service life.

The desktop unit can be placed on a shelf, fixed to a wall, or housed in a racking enclosure.

3.1.1

Wall mounting the desktop unit

Two wall mounting brackets are supplied with the desktop unit. The procedure for attaching
the unit to a wall is as follows:

1. Choose a flat, level wall, strong enough to support the weight of the unit.
2. Offer the supplied drilling template to the wall, marking the location of the two

screw holes.

3. Drill the wall with a 5.5mm (7/32") drill bit and tap one of the supplied wall plugs into

each hole.

4. Fit one of the supplied screws into each plug.
5. Hang the unit on these two screws.

3.2

CABLES MUST BE CONNECTED BEFORE APPLYING POWER

This will involve connecting up the relevant cables to the front and rear of the unit. It is
recommended that the user read this manual prior to set-up to gain an understanding of the
operation of both the units and the software used to control the units.

3.3

CONNECTING POWER TO THE UNITS

The power up sequence will begin after power is applied.

Desktop units require -48V dc (or 110/230V ac to an external adaptor).

The unit must be connected to a protective earth using a suitable bonding conductor.

On the desktop unit, there are twelve LED’s: Status, Ch1, Ch2, Ch3, Ch4, Optical 1, Optical 2,
Master, Test, Local loop, Loop back and Remote loop. When power is applied to the unit, the
front panel LED’s are illuminated as follows;

1. All 3 loop button LED’s will illuminate and the Test LED will flash.

2. Loop LED’s extinguish,Status and Master LED’s illuminate briefly.

3. Status and Optical LED’s should then be illuminated only.

The unit will then be in a ready state for customer configuration.
