WS-2300 without a base

[Mario Matovina]

Hello everyone.

I got a WS-2300 from a friend who didn't know how to use it. He gave it to me without a base. I don't think that he has it. So I have been experimenting with it. I figured out that if I connect oscilloscope to middle two wires that would go into a base I can get a signal. The problem is that before trying to decode information, I would like to know if the base sends some kind of signal to the rest of the station? So, does the central unit (WS-2300-25) expects some order from the base to start sending data or does it sends data anyway? I want to know if I can just record data from those 2 wires and decode them. When I power up the station, I get 8 packets of 48 bit data every 7 seconds.

I have (a long time ago) modified a WS2300 sensor transmitter to give frequent wireless update (every 8 seconds).

The mod 'tricks' the transmitter into thinking a wired console is connected and makes it transmit every 8 seconds, which is a useful update period.

It does make it use a little more battery power and their life will be shorter, but maybe a small solar panel and re-chargeable batteries will eliminate the need to change batteries every 3 months or so.

You could do the mod to the transmitter and then capture and decode the radio signal (I did get it going, but have lost the info I used).

In fact, my modified WS2300 is running here (it is not cabled, but is using the console to capture and provide the sensor data every 8 seconds)

Anyway, try the frequent wireless mod (be careful as the original mod was incorrect on where to solder one of the capacitors - Google it to double check).

Decoding the wireless signal (this was one of the first to do it, but I did get it running straight into a PC - Google will be your friend here).

Good luck and an interesting project, keep us informed how you get on...
