I hope someone here can help. I have been assigned the task of setting up our ELK M1 gold and setting up the rules. This system untill I started working on it has never been tured on as far as I know. Here is our set-up (Elk M1G w/ Elk M1DBH data bus hub, connected to the hub are a keypad, Elk M1XIN zone expander, and Elk M1XZW. Conneted to the zones are Sensorswitch CM-9 R and CM 6 R occupancy sensors) Now for my problem. When I first tured on the system and had a computer connected to the panel with a RS 232 serial cable, I was able to connect to the panel with ELKrp. I noticed the occupancy sensors were conneted wrong .ie Red to Neg and Black to Zone. I tured off the panel and disconected all the sensors and connected them back one at a time and tured the panel back on to find what wire went to each sensor ( as there was no documentation or labling of wires). After reconnecting all sensors I can no longer connect with ELKRP. The error it gives when I try and connect is RP Access Code does not match system or durring connection "detecting serial port settings" it says "System did not respond. Cannot detect baud rate setting." The RP Access Code was not changed by me or anyone else at my location. I also tryed to connect with all sensors disconneted from the panel and this is where I got the RP Access Cose problem. I am new to this and any help would be great.
