T-1210-R
T Technische Mitteilungen
RS232 control of the FM-Tuner T 1210 R
The T1210R can be controlled by any control device having a RS232 serial output port (PC,
CRESTRON home automation system etc.) through the T+A RS232/R-Link interface adaptor.
For details about connecting and operating the adaptor see the user manual of the adaptor
“UM_RS232_Adapt.doc”.
Settings for the RS232 interface of the control device are as follows:
Baudrate: 115.200
Data Bits: 8
Stop Bits: 1
Parity: none
Flow Control: none
T+A RS_232 Protocol
The T1210R uses the standard T+A RS232 command protocol as described in detail in the documents
“TA_RS232_protocol.doc” and “RS_232_Command_Codes.doc”.
Format of the command telegrams
A command telegram to the T1210R consists of 6 bytes. The complete telegram should be sent
without pauses between the bytes.
Example: SYSTEM_ON command
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6
