Has anyone had any experience with hotel motel pms using the Pva card? Have tested w/Pms 90 dos pgm(serial)and Ip emulators. For some reason both NEC pgms received multiple maid status changes(app 20-30)intermittantly w/the same room and code. The pms company will lock up and not clear.Did not have any luck w/IP Interface.
Any suggestions.

I had one locking up. Ntac sent a card with V1.00A on it. The one taht didn't work was V1.00

Just an update.
My system has been running without the interface shutting down. I have set the pva card to mask maid status codes. Also I hve asked the the pms comp to set the ru there for every 30 secs.

Good to know. Thanks for the update.
