This section describes the electrical characteristics of the Remote I/O
module, the Shark Interface module, the AutoMax Remote I/O Head,
and the AutoMax Remote Drive Interface Head.
2.2.1 Remote I/O Module (M/N 57C416)
The Remote I/O module contains a microprocessor that connects to
one port of the dual port memory while the other port interfaces with
the Multibus backplane. A block diagram is shown in Appendix B.
The module contains a watchdog timer, which is enabled when
power is turned on to the module. The onĆboard microprocessor
must reset the watchdog timer within a specified time or the
microprocessor will shut down and the OK LED on the faceplate will
turn off.
