Pin Signal Description Connection to
1 I/O Gnd IO Board Gnd Pin 2 when no power is available from the flash
2 Gnd Flash Gnd Flash ground (negative power terminal)
3 Out Strobe out Strobe input on flash unit
4 Stat Strobe status Status output from flash unit
5 FPWR Flash power Power from flash to output circuit on I/O Board
6 24V IO board 24V (Fused0.5A) Pin 5 when no power is available from the flash
The cable from the flash unit is connected to the VIS CAM I/O Board as shown in figure 3.17 and 3.18. There are
two examples shown: one where the output circuit on the I/O Board is powered from the flash unit and one
where the output circuit is powered from the I/O Board.
It is recommended that I/O Board output circuit be powered from the flash unit in order to obtain galvanic
isolation between the two units. In cases where this is not possible (such as when using mains supplied flash
units) power is taken from the I/O Board.
The cable must be shielded and the shield connected to the metal at the cable entry in the camera house. The
switch labeled S3 on the VIS CAM I/O Board must be in position “NIGHT L” (away from connector X5 as shown
below).
