Apc Rj45 Serial Cable Pinout Diagram
- Jan 11, 2019 I need the pinout for an APC serial cable. The pinout is different to a Cisco console cable, I believe some of the pins on the RJ-45 (UPS) end are shorted together. This is the cable I need to re-create temporarily so I can update the damn firmware.
- Serial port: Access internal menus by connecting this port (RJ-11 modular port) to a serial port on your computer, using the supplied serial cable (APC part number 940-0144). The cable 940-0144 on amazon would cost me 95$ with shipping and tax. There is one on ebay a bit cheaper.

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
