VRC0P Garbled Serial Data

[tehbrosta]

Hello All,
 
I'm having a hard time getting my ELK M1 panel to control my kwikset lock. I have my zwave network setup and I can control the lock from the installer tool. I have the VRC0P setup for RS232. I hooked it directly up to my PC and I'm getting a garbled output. It's suppose to be ASCII out, so I'm sure this is my problem. Now I purchased the unit on eBay and the seller confirmed it was taken out of a working setup, but I did not get the serial cable. I have a DB9 to RJ11 adapter and a serial cable to make it "work."  I actually took the adapter apart and according to a diagram I found on google my ground was on pin 4 of the rj11 and not 3. So I tied both pins 3&4 together, same outcome.
 
Any ideas?
 
I would post a pic, but I'm a new member so I'm not allowed.

You have to issue a command to the VRC0P to set the baud rate, but of course you have to be on the right baud rate to issue the command. So you should probably try that command at each common baud rate from 9600 and work upwards, until you get a non-garbled response, each time indicating the rate you'd like it to us. When you get a response that works that'll be the rate it was at and it should now be on the new rate.

I found the VRC0P programming manual outlining what you recommended to try.
 
I tried all of the following options:
 

SPx where x can range from 0 to 4 corresponding to the specified baud rate;
0 = 9600 (default) 1 = 19200 2 = 38400 3 = 57600 4 = 115200

 
The only baud rate that gives me any response back is 9600.
 
 
Maybe my serial cable is too long, I have a 7ft RJ11, an adapter and a 7ft serial cable connecting the two devices together.

When you adjust the baud rate of the VRC0P you also have to adjust putty to the corresponding baud rate. 7ft is a very short distance for serial unless you have it running across something that is extremely noisy electrically there should not be any issue with the length.  I'm running 19.2k serial over unshielded phone wire for about 10' without any issue at all. (not recommended but it's what I had at the time)

I got it, I had to reverse my yellow and black wires on my RJ11. 
 
 
RJ11 DB9 PIN-OUTS
4 (BLACK)  ----  2 (TX)
3 (RED)      ----  (Not used)
2 (GREEN) ----  3 (RX)
1 (YELLOW)  ----  5 (SGND)
