• Control signals come from a standard digital I/O board.
First, remove any jumper wire from TB7. Then, observing polarity,
connect the external power supply to the terminals and -,
as shown in Figure 2-3. Note that failure to observe polarity will
blow Fuse F25.

come from a standard digital I/O board.
• Control signals come from a KPCMCIA-PIO24 module.
The KPCMCIA-PIO24 does not 5V to the SSIO-24. There-
fore, you must supply all +5V signals externally, including the +5V
that a PC would otherwise supply to the PC terminal on TB7.
On Terminal Block TB7, connect a jumper wire between the termi-
nals marked PC and + (the default setting). See Figure 2-4.
