Connecting Strobes

Strobes for I/O Options 1 and 2

For I/O connection options 1 and 2, you can wire your strobe device either to the TTL
pins or to the opto-isolated pins on the I/O connection module. The choice between TTL
and opto-isolated wiring is independent of the currently loaded I/O configuration option.

Use the pins described in Table 6 and illustrated in Figure 13.

Signal names are explained in
