Well, I'm cheap and lazy also. On the front of the control panel is a center off Access Disable switch, SW801 sp3t (on-off-mom). I took a shielded wire, soldered the shield to the center contact and the center to the "on" contact, i.e., the ACC DIS position.
I ran the wire to a friends UHF controller with a spare latching relay. Connected to the N.O. contacts on the relay. Done! One code latches the relay disabling the MSF5000, another unlatches it. P.S. I do plan on putting my own control receiver and DTMF board on line eventually. Have fun! Ken --- In [email protected], "Bob M." <msf5kg...@...> wrote: > > Not only am I cheap, I'm lazy. Building something takes time. I was mainly interested in a product I could buy that just needed power, incoming audio, and a set of dry contacts that could be stuck inside the MSF5000 cabinet and be ready to use in a matter of minutes. > > The DTMF decoder in the MaxTrac also needs to be programmed, and it uses different software than what would be needed for the MSF5000, of course.
