Cat. No. 771 Remote Fader Installation
The Cat. No. 771 Remote Fader can be mounted on a wall or in a console, or can
stand alone.
To install the remote fader:
1. Remove the four screws from the corners of the front-panel. Store the screws
nearby and remove the rear housing.
Caution:
Do not touch circuit-board components. Static electricity can damage
components.
2. Make a hole in the housing for the interface wire. We recommend you place the
hole on the bottom if the remote fader will be mounted, or on a side if the fader
will stand alone.
3. Use a two-conductor shielded cable (Belden 8451 or equivalent) to connect the
remote to the CP650. To prevent wear on the cable from the metal edge of the
hole you create, use a rubber or neoprene grommet on the cable. The diameter of
the hole you make should be the same as the diameter of the cable grommet or
conduit bushing.
4. Thread the interface wire and attach the +voltage, data, and ground wires to the
interface connector as shown in
Figure 8–3.
5. Use a small flatblade screwdriver to set address switch SW2.
Do not set the
arrow to the “0” position
, because that setting generates an error message and
disables the unit. It is not important what number any single unit is set to, but no
two remote units can be set to the same number, so record what address you set
for each unit. If your installation includes only one remote unit right now, it is still
a good idea to record the setting in case you add another remote later.
6. Replace the housing, pulling the interface cable tight enough to keep it from
touching any components on the circuit board.
7. Secure the front-panel to the housing with the screws you removed in Step 1.
8. Connect the interface cable to the CP650 as shown in Figure 8–5.
