I/O Module Compatibility

I/O Modules not
Compatible with
TI545/TI555 CPUs
C-2 TI545/TI555 Controller and I/O Compatibility
Unmodified Series 505 discrete I/O modules manufactured prior to
January, 1988 are unable to report module status and, therefore, cannot be
recognized by the TI545/TI555 CPU (that is, inputs are not read and
outputs are not written). Series 505 discrete I/O modules manufactured in
January, 1988 or later and those manufactured prior to this date that have
been modified contain the status reporting mechanism and are compatible
with the TI545/TI555 CPU.
The Series 505 Simulators (PPX:505–6010, 32-Input Simulator and
PPX:505–6011, 32-Output Simulator) are also affected by this compatibility
restriction.

NOTE: Note in Table B-1 indentifies all affected modules.
The following modules are fully compatible with the TI545/TI555 CPU,
regardless of the manufacturing date.
All Series 500 I/O and all non-discrete Series 505 I/O, such as analog
modules (except for the High Speed Counter, as described on page C-3)
Series 505 Word modules (PPX:505–6308, 8-Channel Word Input and
PPX:505–6408, 8-Channel Word Output)
