Revision 06
Local control:
The AVS-1210 is manufactured as a slave format switcher with no local control panel.
Two local control panels are available; the CPS-1210 and the CPS-1220 with 10 and 20 buttons respectively. A
switcher fitted with the CPS-1210 may be upgraded to 20 buttons by conversion kit CPS-1215.
CPS-1210 fitting: (10 buttons)
1.
Disconnect IEC power input plug from chassis and remove chassis from rack.
2.
Remove 6 screws holding top cover (1 each side and 4 in top). Remove top cover.
Remove 6 screws holding front escutcheon to front chassis and remove escutcheon.
3.
Separate the switch PCB from the switch logic PCB and mount the switch PCB in the chassis cutout using the 6
screws and stand-offs provided. The PCB should be mounted so that the LED's in the switches are at the top.
Re-fit the switch logic PCB to the switch PCB by locating PL 1 & PL 2 over the two sets of connector pins and
pressing firmly and evenly into place.
4.
PL 4 on the control panel is then connected to PL4 on the rear of the switcher.
PL 5 on the control panel is then connected to PL4 on the switcher PCB using the 150 mm cable provided
(GDW-3010).
The connection from PL 5 on the switcher PCB to PL 5 on the rear of the switcher is left untouched.
5.
Check the position of links LK 2 & LK 3 on the switch logic PCB.
For switches to operate 1 - 10 LK 2 should be OUT.
For switch panel to operate as tally only LK 3 should be in position A.
For front panel switches to be operative LK 3 should be in position B.
6.
Fit new front escutcheon using the original 6 screws.
Re-fit chassis top cover using the original 6 screws. The two countersunk head screws are used at the front top
of the cover. Note that the top cover sits on top of the chassis at the rear, but under the fold at the front.
7.
The switcher is now ready to re-install in the rack.
CPS-1220 fitting: (20 buttons)
The procedure is the same as for the CPS-1210 except that two sets of switch PCB's are fitted.
Normal 20 x 1 operation.
1.
As per CPS-1210.
2.
As per CPS-1210.
3.
As per CPS-1210. Repeat for the second PCB.
4.
PL 4 on the 11 - 20 switch control panel is then connected to PL 4 on the rear of the switcher.
PL 5 on the 11 - 20 switch control panel is then connected to PL 4 on the 1 - 10 switch control panel using the
300 mm cable provided (GDW-3011).
PL 5 on the 1 - 10 switcher control panel is then connected to PL 4 on the switcher PCB using the 150 mm
cable provided (GDW-3010).
The connection from PL 5 on the switcher PCB to PL 5 on the rear of the switcher is left untouched.
5.
Check the position of links LK 2 & LK 3 on the switch logic PCB's.
For the 1 - 10 switch PCB LK 2 should be OUT.
For the 11 - 20 switch PCB LK 2 should be IN.
For switch panel to operate as tally only LK 3 should be in position A on both PCB's.
For front panel switches to be operative LK 3 should be in position B on both PCB's.
6.
As per CPS-1210.
7.
As per CPS-1210.
