NOTES:
❏
The handshaking is set through the DIP switches on the TM series printers. The choices indicated in parentheses
above are typical choices or a typical range of choices that are supported by the 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.
Signal levels and communication control functions
Data transmission:
Bit serial
Synchronization: Asynchronous
