position for the other. For example it could be set to the Lower position for the Indigo 2SE
CoolFlow frame and Upper for an Indigo 2 CoolFlow or Indigo 1 CoolFlow frame.
The number of modules reported to the active display includes the PSUs and front
panel/frame as the Indigo front panel PIC and the two power supplies have an address and
are treated as modules. Refer to the address range table in Chapter 3 - 'Operating the active
panel' for more information.
The two frames should be connected so that control can pass from one frame to the other
using an RS422 serial link.
Note:
The switch will only have an effect the next time the front panel is powered up.
Establishing a serial link
This can be accomplished with a special cable linking the Remote 2 connectors or by using
a CAT-5 patch cable linking the '422 Bus Output' connectors.
Using a CAT-5 patch cable
A CAT-5 cable (TIA/EIA 568A CAT-5 PATCH) is plugged in the connectors labelled ‘422
Bus Output’ on each frame.
Using Remote 2 connectors
A special cable is connected between the 'Remote 2' D-Type connectors of the two frames.
The cable required uses two female 26 way high density D-Type sockets. These should be
connected with screened twisted pair cable containing two pairs. All the wiring is pin to pin.
Pins 16 and 7 should use one twisted pair, pins 17 and 25 the other. The screen should be
connected to pin 6 on both connectors.
Note:
The Comms LED will flash when communication has been established.

Frame link cable connections
To ensure continued EMC compliance it is recommended to use high quality shielded twin
pair cable for RS422 cabling.
