Note that APC UPS serial cable part numbers follow a numbering scheme
|
|
where the "940-" prefix identifies them as cables.
|
|
|
|
940-1000 straight through cable
|
|
940-0103 null modem cable
|
|
940-0020 Basic Signaling Cable (OB and kill power)
|
|
940-0023 Simple Signaling Cable (OB only)
|
|
940-LL24 Smart Signaling Cable
|
|
940-0095 PnP Cable (see Apcupsd manual for diagram)
|
|
940-0119 Simple Signaling Cable (OB and kill power)
|
|
940-0127 RJ45-10P10C to USB Cable
|
|
940-0128 Simple Signaling Cable for Back-UPS CS
|
|
|
|
"LL" represents the length:
|
|
|
|
00 six feet
|
|
NN NN feet
|
|
|
|
The suffix letter represents a minor revision in physical design, or a
|
|
change of OEM, _not_ a change of wiring or pin-out, and all cables
|
|
differing only in this suffix letter are electrically interchangeable.
|
|
Note though the following quote from the APC Discussion Forums: "At one
|
|
point there were a small number of revision D cables [940-0024D] that
|
|
had some shielding issues from the manufacturer that could maybe cause
|
|
[...] [spontaneous] self-tests)."

|
| Operation: The UPS communicates with the Computer via |
|
|
| the RS-232 handshaking lines only, and does not use any |
|
|
| serial protocol. Upon power fail, the UPS forces CTS to |
|
|
| -V MARK. When the battery is low, the UPS forces DCD to |
|
|
| +V SPACE via the transistor. When the Computer forces a |
|
|
| +V SPACE on DTR, the UPS will shut down and turn off. |
|
|
| Presence of the cable can be sensed by signaling on TXD |
|
|
| while monitoring DCD. |
