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.
Simple scheme (APC 940-1524D cable)
| UPS Signal Name |
DB-9 Male (UPS end) |
DB-9 Female (PC end) |
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
