Figure 4-1. 6533 Device I/O Connector Pin Assignments
Note: In Figure 4-1, the * indicates that you can reverse the pin assignments of
the ACK1 (STARTTIG1) and REQ1 pins, or the ACK2 (STARTTIG2) and
REQ2 pins, with software. This can be useful when performing two-way
ACK/REQ handshaking between two 6533 devices over an SH68-68-D1 or
similar cable, because it allows you to connect one device’s ACK pin to the
+5 V
