Device Settings When Software Requires XON/XOFF Handshaking with Jumper
JP32 Shorted
To set XON/XOFF handshaking, check that the IR-320 and the TM Printer use the following
settings:
❏
Handshaking for the TM-xxR Printer should be set to XON/XOFF.
❏
Set DIP switch 1-3 of the TM-xxR Printer to ON. (The default setting is OFF.)
❏
Set Jumper JP32 on the POS board to SHORTED. (This is the default setting.)
❏
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 still controlled by hardware handshaking (RTS/CTS).
Notes:
You cannot use DTR/DSR handshaking to control the TM Printer.
The Customer Display is set to RTS/CTS to keep it from going BUSY.
