Notes:
❏
Handshaking is set through the DIP switches on TM series printers. The choices indicated in
parentheses above are typical choices or a typical range of choices supported by TM series printers.
❏
DR1 > DR2 CS1 > CS2 indicates that:
Channel 1 is HIGH.
Channel 2 is LOW.
❏
DR1 < DR2 CS1 < CS2 indicates that:
Channel 2 is HIGH.
Channel 1 is LOW.
Data transmission: Bit serial
Synchronization: Asynchronous
Handshaking: Depends on the DIP switch settings
(DTR/DSR or XON/XOFF control )
Signal levels: 2.0 V to 5.0 V: Logic 1
0.0 V to 0.8 V: Logic 0
Baud rates: Depends on the settings of the TM series printer
(2400 to 19200)
Data word lengths: Depends on the settings of the TM series printer
(7 or 8 bits)
Parity settings: Depends on the settings of the TM series printer
(None, even, odd)
Stop bits: Depends on the settings of the TM series printer
(1 or more)
