Why is my new SMX1500RM2U is "ignoring" me?

[BillP]

I've a new SMX1500RM2U manufactured in October 2012 with firmware 9-1 installed. I've been able to work with the unit via a borrowed AP9630 but not via USB or Serial.

The USB port is working becasue, when plugging in via the USB cable, my Windows 7 x64 machine sees it and installs the driver for the device. When trying to hyperterm using the serial cable with the Win7 machine or an older XP Pro machine, I get zero, zip, nada, zilch.

Any thoughts what I am doing wrong?

Two things:
- The older SUA line of UPSes spoke UPSLink, while the newer SMX line speaks Microlink. If you're trying UPSLink commands, you won't get a response.
- The older SUA line of UPSes provided access to the NMC via the serial port on the UPS. The AP9630 isn't accessible the same way. It ships with a configuration cable that plugs into the little phono-jack. Configuration operates at 9600 baud, 8n1.

If you want to test the serial port on the SMX1500RM2U, you can configure PowerChute to communicate serially.

Got it and thanks for the helpful hints!

In hindsight, it's the new micro-link protocol that's the root of my problems.
