7.2.3 Communication Specifications of Communication Cassette
Serial communication specifications (1:1 communication)
(
*
Note 1)
Item Specification
Communication method
Half-duplex communication
Synchronous method
Start-stop synchronous system
Transmission line
RS232C
Transmission distance (Total length)
15m/49.21 ft.
Transmission speed (Baud rate)
2,400 bits/s to 115.2 k bits/s (*Note 2)
Transmission code ASCII
Transmission data format
Stop bit: 1-bit/2-bit, Parity: None/Even/Odd
Data length (Character bits): 7-bit/8-bit (*Note 2)
Interface Conforming to RS232C (Connection using terminal block)
Notes
1) The RS232C type of communication cassette is necessary in
order to use the serial communication function
(1:1 communication).
2) The transmission speed (baud rate) and transmission format
are specified using the system registers.
