When the port connected to the TM or DM-D is selected, the connection is confirmed and the
results are displayed. If the TM or DM-D are not connected, select None.
Notes:
❏ Because this program obtains the serial and parallel port settings from the PnP BIOS, the
BIOS Setup Utility must be correctly set up.
❏ When the TM printer and DM-D are connected to the same serial port, make sure the
communication conditions are the same.The communication conditions are recognized
automatically when both devices are connected to the same serial port and when the TM
printer is used by itself.
❏ If the settings differ from the actual communication conditions of the TM printer and DM-D,
garbled characters may be printed or displayed as the devices interface with the system.
❏ The devices can support a communication rate of up to 38,400 bps.
❏ If the TM printer is connected to a serial port different from that of the DM-D, the tests
cannot be conducted at the same time.In this situation or when the DM-D is used by itself,
set the DM-D communications settings to 9600 bps, 8-bits, and with no parity.
