Instruction Manual
Unit Address
As all CTUs have the same address by default, the next thing to do is to set a new
address to CTU. This can be done by using unit’s serial number as the identifier when
setting a new address. The valid address for CTU is between 0x10 and 0x4F. To set the
address, the following request as in Table 10-13 is used and the response as in Table
10-14 will be sent back.
Request :
Command RR Source Dest Data Remarks
0xEF 0 Source ID Dest ID [0-5] Serial
[6-7] Node
ID Serial number
The new node ID

Response :

Result > 0: Error
Table 10-14: Unit address response
Warning - CTU will use the old address when responding. After sending response it will
change the address.
Example:
Using PCANView application to send and receive messages, I sent message
13C001F1 (ID in hex) with data set to 00 02 00 00 06 D2 00 10. The ID of PCANView
(acts like host) is 1.
The bytes 1 to 6 (starting from left most) of the data represent the serial number and
bytes 7 and 8 represent the new address for CTU (in this case 0x0010)
