Wireless probes/ets’s (ets’? don’t hate me grammar police) will go to an idle state after a period of inactivity to save battery life. When they need to be used a signal is sent over whatever communications protocol is used to wake up the device which then responds with an “I’m ready” response. I haven’t fully disected the owners manual but I suspect the communications protocol is not documented there anyway and there is precious little in the way of photos of the probe, ets, or interface module. BUT!! In the owners manual, there are a few terrible photos of the different components and between them, you can just make out the brand name Pioneer, and the text “400” on the probe, indicating an OPS-40 probe and it’s associated module. Documentation, including the wiring pinouts can be found in their owner’s manual here
@Dr_Harold_Jones The 5th wire on your tool setter is likely an overtravel alarm output and can be ignored since your 1100 isn’t setup to detect or respond to that.
