Pin numbering is as follows:
Pin Signal
1. GND reference (LK 3A connected)
2. Switch 1 contact
3. Tally out 1
4. Switch 2 contact
5. Tally out 2
6. Switch 3 contact
7. Tally out 3
8. Switch 4 contact
9. Tally out 4
10. Switch 5 contact
11. Tally out 5
12. +5 Vdc 560 Ω sourced feed for tally LED’s.
Tally lines are pulled low when active and an indicating LED may be directly connected between the pin 12 current
source and the tally line for each crosspoint.
Where it is not convenient to connect directly to a switcher in the above manner, the same procedure may be
followed using a CPS-9000 remote control panel connected to the switchers using the standard encoded remote
control cables. In this case, the switch panel for the CPS-9000 should be removed and the wire per crosspoint
control connected in its place. Hence, the CPS-9000 will act as a wire per crosspoint to BCD encoder for the
connected switches. The CPS-9000 may be built into other equipment or fitted with a blank front panel and
mounted in a standard Eurocard frame.
The CPS-9001 remote control panel may be used in a similar fashion to the CPS-9000. However, if remote wire-
per-crosspoint control is required without tally, this may be accomplished without accessing the front panel
connector. A special connector is provided on the CPS-9001 for remote wire-per-crosspoint input. This is connected
directly to the switch panel wiring.
