Cloud Electronics CX263 - Manual (Page 15)

9 Optional Modules
There are only two types of internal optional modules which can be fitted to the CX263:
M CDI-S200 serial interface card
M Bose Active Equalisation Modules
9.1 CDI-S200 serial interface card
The CDI-S200 is an RS-232 compliant, serial interface option card for the CX263. The CDI-
S200 can control:
M Music source selection and level in any zone
M Individual microphone mutes
M Music Mute
M Microphone access switching for Microphone 1
Installation:
1. Switch off the mains supply to the CX263 and remove the CX263’s power lead.
2. Remove the unit’s top panel.
3. Remove the blanking plate covering the hole for the serial interface card in the rear panel.
4. Remove the hex pillars connected to the 9-pin sub-D socket.
5. Configure the CDI-S200 to operate at the correct baud rate and flow control. It is simplest
to do this before the module is fully installed.
6. Locate and remove the M3 screw in front of CON 2 and the M3 screw directly to the left
of it, closest to the small network of diodes. Both screws are indicated on the white PCB
legend with large arrows. Keep the screws.
7. Install a 25mm hex pillar (supplied with the module) into each of the screw holes from the
previous step.
8. Connect the module ribbon cable to CON 2 on the mainboard.
9 Install the CDI-S200 in the inverted position, such that the 9-pin sub socket fits snugly
through the hole in the rear panel, and the two holes at the back of the card are in line
with the hex pillars rising up from the main board.
10. Insert the hex pillars taken from the module socket through the holes in the rear panel into
the CDI-S200 socket.
11. Use the M3 screws saved from step 6 to affix the rear of the board to the hex pillars rising
from the mainboard.
12. Configure jumpers J19-24 and the rear panel switches to allow the CDI-S200 to control
music functions in the zones you select. In order for the CDI-S200 to control the music
functions in a zone, the rear panel switches need to be in the ‘REM’ (in) position and the
‘DG’ (out) position.
13. Configure jumpers J4-6 to enable/disable serial control of the microphone 1 access
switching.
14. Replace the top panel
NOTE: PCB jumper markings indicate the position of the link as a filled box.
