      These are the things to do to configure apcupsd to a legacy APC UPS using a 940-0024C Smart Serial Cable,

      to a MiniSys (ProtectLi) computer with a RJ45 COM port.

      1. Must install pFsense VGA, single COM port will be dedicated to UPS.

      2. Minisys BIOS = Disable COM redirection. In Addition I set mine for 2400,n,8,1 or whatever speed ur UPS is currently set.

      3. Install apcupsd pkg and configure with params below.

      4. Build and use cable as shown below.

      /usr/local/etc/apcupsd/apcupsd.conf

      This Doc created 3/14/2018. pFsense 2.4.2. FreeBSD 11.1.

      Name your UPS

      UPSNAME YOUR_UPS_NAME

      Legacy APC serial port

      UPSCABLE 940-0024C

      Smart Signalling

      UPSTYPE apcsmart
      DEVICE /dev/cuau0

      Leave the rest of params at default or customize to suit your need.

      Now you must build and use this custom cable, pinout as follows:

      Short pins 1 - 8.

      #    RJ45    DB9-M

      +– 1

      |

      +-- 8

      #      3 ----- 1

      #      6 ----- 2

      #      5 ----- 9

      Here's one: https://www.monoprice.com/product?p_id=1151

      #END

      UPDATE: Even Simpler. Use an USB-Serial dongle like the popular Prolific PL2303 which FreeBSD 11 has built-in driver, coupled with 094-0024c will do it. Then u save the 1 com port for console use. Mine came up as port cuaU0 (uppercase U) when hooked up to the USB3. So config DEVICE /dev/cuaU0.
