2.4.3
Scanner Chassis Grounding Jumper Settings
The scanner chassis grounding method can be selected by positioning a jumper (see
Figure 9). In this way the scanner chassis can be connected to earth ground (only if
pins 7 or 8 are connected to a good earth ground) or to the power supply ground
signal. The scanner chassis can also be left floating but, in this case, the jumper
must be removed.
The C-BOX 4X0 is now installed which completes the electrical connections for your
scanning system.
2.4.4
OM4000 Jumper Settings
The jumpers allow connection to the EXT TRIG signals on separate spring clamp
terminals for applications which use the OM4000 Oscillating Mirror in Trigger Mode.
They are used together and they have the following significance:
when a jumper is in the J1 position (see Figure above) pin 40 is connected to pin 27
(EXT TRIG+); a jumper in J2 position connects pin 20 to pin 28 (EXT TRIG-).
If the jumpers are removed pin 20 and pin 40 are disconnected.
