[Nut-upsuser] Richcomm Serial driver
Hi, I'm trying to configure my ups with nut which is a locally made one. It uses a rs232 port to talk to the computer and comes with a software called Powermanager Lite which is provided by Richcomm and supports Windows, Linux and UNIX. According to the manual it uses the Richcomm circuitry to talk to the computer and uses a drycontact protocol. Unfortunately I couldn't find any driver for Richcomm serial interface, there's a richcomm_usb however. I've tried all of the genericups drivers and the megatec driver even a USB to Serial converter cable (Prolific chipset) but no luck. Any suggestion about which driver to choose or what I'm doing wrong? I'm using NUT on FreeNAS 0.7.2 which uses NUT 2.60. Below is the link to the Richcomm product product page.

If not through one of the existing 'upstype' settings, you should be able to override the 'CP', 'OL', 'LB' and/or 'SD' configuration directives to make it so. This is essentially what the 'richcomm_usb' driver does for USB. I'm using NUT on FreeNAS 0.7.2 which uses NUT 2.60. Below is the link to the Richcomm product product page. Powermanager lite: http://www.richcomm.com/en/productshow.php?ippt_product_id=65 This is not a description of a dry contact interface. If this is what your UPS is using, it requires something different. Assuming the people who designed this did not create a smart protocol using the modem control lines (which would be insane, since using the TXD/RXD lines would be much simpler instead), I would say this is a smart protocol which is not supported through either genericups or richcomm_usb. The best advice we can give you is to first find out what protocol is used by the UPS (possibly by snooping the serial port when running the bundled software). Unless you have dozens of devices you have to use and/or you hourly wages are close to zero, it is probably better to ditch the UPS and buy something that is supported out of the box.

[Nut-upsuser] Richcomm Serial driver
Thanks for your replay. Actually my UPS uses a lite version of that software and only reports mains on/off, ups on/off and ups connected/disconnected status. I also think the genericups driver should work and tried all the driver types without any luck. Unfortunately I can't afford to ditch the UPS right now. I'll try the serial sniffing technique or use a multimeter to find out what's happening through the serial port. I've some experience with those. Can you give me some idea what I should be looking for? One more question. Is it possible to use a USB to serial cable for a serial UPS with generic UPS driver? This combination works in Windows with the official software but what about NUT? Is any special configuration required for this? Thanks again...
