Weeder WTDOT-M Card Addressing

[James Sentman]

Hello George,

Yes, things are a bit hectic but hopefully I’ll be able to catch up before too long.

I don’t see that I’ve done specific support for the WTDOT-M card. For outputs I’ve used the WTDIO card in which the pins can be either input or output. There is no selection specifically for the WTDOT-M device yet. I can almost certainly add that specifically in the next release. In the meantime it MIGHT work to configure it as the WTDIO card. It might throw constant errors as it tries to poll for changes, or that might work just fine I have only glossed over the specifics just now and can’t pretend to have a detailed understanding of the consequences of polling it as if it were also an input card.

When I use the input/output card it works fine though. I use it to control several similar relay devices. You do have to either use a relay device with a transistor and snubber diode and such on board or add it yourself as you cannot power the relay direction from the output on the weeder without potentially damaging it. If you have the proper relay type device then you should be able to do so. Experiment with just setting it up as a WTDIO card and then give me a bit of time to implement the specific protocol of the WTDOT card for the next release.

The WTDOT-M card is a digital output card with 8 digital output points.

All I'm trying to do is close some dry contacts on the card to close some dry contact switches on a IC Realtime security DVR Alarm input pins. According to James', Weeder WTDOT-M instructions, no special programming using Terry Weeder's WTDOT-M is necessary. Terry Weeder is of the opinion I have to use his PC software to program his card to go from high to low on an output pin which is what he says is the problem.

All I'm looking for is the momentary closure of it's dry contact alarm inputs. I merely have these two lines in the PIR's On script, and they are working as far as XTension is concerned, as it's LED in the Master List turns red for 3 seconds and then returns to green. The DVR is programed, upon closure of these contacts to trip a 10 second cycle to make the particular camera be the front picture on the monitors for 10 seconds.

Thanks,
