Mod 8
Monitor tube change from 40CB4M to 40JB4.
Resistor changes to suit new monitor:-
R111 – Wire Link
R112 – 15M
Ω
R113 – 10M
Ω
R144 – 5M6
Ω
In some later cases the heater requires a resistor in parallel
(P104 pin 3 to pin 6) to obtain the correct split between
Pevicon and CRT. This should be added / adjusted for 5.8 to
6.0 V across the Pevicon heater.
(December 1990)
Mod 9
Modifications for CE marking (EMC compliance). Cameras
are numbered from 6000 onwards.
New VSU PCB and mechanical design (applied to all
cameras)
VSU to camera cable changed.
Front Plate and Lens wiring changed.
Chassis changed (applied to all cameras)
Change to RF screen
Note that the spare parts for these cameras are different and
not compatible with previous MOD levels. Always quote the
serial number when ordering spares.
(January 1997 for EC customers)
Mod 10
New Scan PCB (DAS 547526 AA)
New Video PCB (DAS 547584 AA)
Boards redesigned due to component obsolescence issues
and now using surface mount parts. These are fully
compatible with the older board types and will be supplied as
spare parts.
Minor setup differences:
Battery indication no longer adjusted (setup 28)
Pan signal level automatically adjusted (setup 15)
No data phase adjustment (setup 20)
Some pot directions changed, see text.
Select on test resistor for CRT heaters now on PCB (R200)
(March 2000)
Mod 11
New boards as Mod 10 to EMC build standard. (June 2000)
