Serial Handshaking
Overview of the TM Printer and the Customer Display Connections
The recommended control line connections for the TM Printer and its peripherals are the default
settings. These are DTR/DSR flow control for the TM printer and RTS/CTS flow control for the
Customer Display.
Possible Combinations of Handshaking for the TM Printers and the Customer
Displays
When a TM-T88IIR, TM-U210AR, or TM-H3000R printer is installed on the IR-320, the DTR/
DSR line is internally connected to the TM Printer. As a result of this, customers should use
RTS/CTS line for handshaking with the Customer Display. However, if the customers change a
setting of JP32, they can use the following flow control combination.
TM Printer control:
RTS/CTS
CustomerDisplay control:
DTR/DSR
Connection Differences for Customer Displays
Unlike the TM printers that use a pass-through connection with the Customer Display, the
printers and displays for the IR-320 system have separate connections for separate flow control.
(External TM printers also require separate flow control if a Y connection is selected rather than
a pass-through connection.)
Flow Control Selections for Different Applications
If an application program is written in Visual Basic and MSCOMM is used, only RTS/CTS and
XON/XOFF are available for selection. In this case, you can set the TM Printer and the Customer
Display as follows using the ActiveX control MSCOMM:
TM Printer control:
XON/XOFF
CustomerDisplay control:
RTS/CTS
Notes:
CustomerDisplay control cannot be guaranteed with XON/XOFF.
DTR/DSR handshaking is not an option with the MSCOMM control.
