APC Part# 940-0024A, 940-0024B, 940-0024C, 940-0024D, 940-1524  cable scheme

According to APC forum, letter suffix is related to (change of?) manufacturer or revision, not wiring, and cables are electrically interchangable.

'Simple scheme' diagram further below looks correct for 940-0024 & A,B,C or D revisions and 940-1524 which is 15' long cable; and matches what viewed on a third-party site.

PC
Signal Name
TX / AC Fail 2 2 Rx, Received Data
RX / Shutdown 1 3 Tx, Transmitted Data
Common 9 5 GND

At the PC end: pins 1,4 (DCD, DTR) shorted; pins 7,8 (RTS, CTS) shorted.
DB-9 shells are also connected.

The 9,1,2 pins look OK for the basic mode, but the smart mode seems to need extra components.
4+9=GND
8=25V
7=5V
