This is a quickstart guide for programming the CTG-KNX/IP or CTG-EIB/NX available at
www.comm-tec.de
.
Both devices have the same protocol, but different interfaces.
Notes:
•
The CTG-KNX/IP allows only one simultaneous IP connection, this means having
the controller and a software simultaneous connected does not work.
•
The gateway has a build in filter table. Only group addresses which are listed in
this filter can pass the gateway, everything else will be deleted!!(see page 2 of
this document)
•
The filtertable can’t be retrieved from the gateway.
Communication parameters:
CTG-EIB/NX
CTG-KNX/IP
Baudrate:
38400 8N1
Use a straight cable (pin 2, 3 & 5)
Port:
10002
Frameformat:
<STX><command><ETX>
<STX> = 02 hex ( 0x02 )
<ETX> = 03 hex ( 0x03 )
<command> = ASCII commands
Commands:
uppercase W is for Writing
uppercase R is for Reading
Samples:
0x02
W10/5/7=1
0x03
Writes the value 1 to the group address 10/5/7
0x02
W1/65/77=100
0x03
Writes the value 100 to the group address 10/65/77
0x02R10/5/70x03
Request the value of the group address 10/5/7
Feedback:
Cylic data, confirmation of a send command(only Echo, if it is turned on)
A>10/5/7=1
When doing readrequests:
A@10/5/70=192
When EIB-Bus is busy:
Try to read 3 times
B@01/0/203 You can make a message bus is busy, but it is useless.
