View Full Version : Siemens Question
02-22-2007, 03:14 PM
Here is what I got. I'm looking to integrate a Siemens system into a FX-40 aka Jace. I have the "jar" file needed in the jace but I'm confused on how to hook it to the Siemens panel. The Siemens controller is a MEC 540-032. I was trying to hook into the MMI port that from my studied is RS-232. I used a RJ-11 to Serial connector and plugged that into my laptop and ran a demo station. The software side seems like it will be fine, I'm uncertain about the connection side of it at this point.
Lets here the ideas!!!

Can you see the MEC menu using hyperterminal? If so, this will prove the connection.

Thank you for the reply. I did try that and I got nothing using VT100, 9600 8-N-1 and I also tried auto detect with no luck.

The default baud rate for the MEC's is 19,200 and of course they can be set to go up to 115k.
The auto detect should work but I've had alot of instances where it didn't. Make sure flow control is off and try baud rates from 4800-57600 manually. At some point, if the cable\port is correct, you will see something, even if it's just garbage characters.
Most likely, you don't have the correct cable. I have the pinouts somewhere, I'll look them up today.

Siemens MMI Cable Pinout:
pin 1 ---> pin 2
pin 2 ---> pin 3
pin 5 ---> pin 5
Baud Rate - 19,200
Data Bits - 8
Parity - None
Stop Bits - 1
Flow Control - No
Emulation - VT100
Dumb question, you sure you selected the correct com (serial) port?, or are you using a USB to serial converter?
Say hi to IndyBlue at the Christmas Party. (just joking)
