There is an input available on the TC1200-0000 Scan Engine relative to the External Trigger
used to signal the reading phase for On Line Operating Mode. The pins are indicated in
Table 1. This input is optocoupled, polarity insensitive and can be drive
n by both an NPN or
PNP type command. The connections are indicated in the following diagrams:
