CoM
Setting content Initial value
1 PRt
Press the MODE key for making a setting effective (including reverse feed).
0
0 TOHO protocol
1 MODBUS protocol (RTU mode)
2 MODBUS protocol (ASCII mode)
Set the communication protocol (communication procedure).
For details of communication, see “TTM-200 series operation manual - communications.”
■ Communication parameter setting
SEt17
CoM
Setting content Initial value
2 CoM
***1 Stop bit length 1 bit
b8N2
***2 Stop bit length 2 bits
**N* Parity none
**o* Parity odd No.
**E* Parity even No.
*7** Data length 7 bits
*8** Data length 8 bits
N*** BCC check nonexistent (settable for TOHO protocol)
b*** BCC check existent (settable for TOHO protocol)
For MODBUS (RTU)
Settable only with 8N2, 8N2, 8o1, 8o2, 8E1 and 8E2.
For MODBUS (ASCII)
Settable only with 7N1,7N2,7o1,7o2,7E1,7E2,
8N1,8N2,8o1,8o2,8E1,8E2
The following is set for communication data: stop bit length, parity and BCC check existent/nonexistent.
For details of communication, see “TTM-200 series operation manual - communications.”
■ Communication speed setting

Setting content Initial value
3 bPS
2.4 2400 bps
9.6
4.8 4800 bps
9.6 9600 bps
19.2 19200 bps
38.4 38400 bps
Set the communication speed.
The term bps (bits per second) refers to the number of bits allowed in communication in a second.
