Option pins on the T
2
CAS computer associated with each of the functions
defined on the Option Pins Status page are listed below. Where more than one
option pin is indicated, the listed connector pins correspond to the display digits
read from left to right.
There are eight option pins available on the T
2
CAS computer for selection of
various options. The OPT PINS are as follows: RMP--10G, --10H, --10J, --10K,
-- 1 1 A , -- 11 B , -- 1 1 C , a n d -- 1 1 D .
NOTE: OPT PINS RMP--10G, --10H, --10J, and --10K are reserved for future
enhancements and are used for parity check only.
The PARITY line (line 4) displays the status of the parity program pin
(RMP--12G). Pin RMP--12G must be grounded (1) when the number of OPT
PINS grounded is an odd number (1, 3, 5, 7). If number of OPT PINS grounded
is an even number (0, 2, 4, 6, 8), then pin RMP --12G should be open (0).
The STATUS line (line 5) displays FAIL if the option pins parity is incorrect or
PASS if parity is correct.
