Device Settings When Software Requires RTS/CTS Handshaking
To set RTS/CTS handshaking, check that the IR-320 and the TM Printer use the following
settings:
❏
Handshaking for the TM-xxR Printer should be set to RTS/CTS.
❏
Set DIP switch 1-3 of the TM-xxR Printer to OFF. (This is the default setting.)
❏
Set Jumper JP32 on the POS board to OPEN. (The default setting is SHORTED.)
❏
The recommended setting for the Windows FIFO buffer is disabled. This prevents timing
delays caused by the data being held in the buffer. If customers want the setting to be
enabled, the manufacturer recommends that the transmission buffer size be less than 16
bytes.
❏
The Customer Display is controlled by DTR/DSR handshaking.
