TM-U220 Technical Reference Guide
2.3.1 Stand alone
Both TM printer and customer display (DM-D) are connected to the host PC via serial port.
2.3.2 Y-connection
TM printer is connected to the host PC via serial port and the customer display (DM-D) is
connected to TM printer via a modular connector.
(*) When RTS/CTS control is used between the TM and DM.
Note:
When you would like to provide power from TM-U220 to a DM-D, you have to use “PS-180.“ The “AC
Adapter C” can’t provide power to a DM-D.
You need to use the UB-S09 interface when you use a modular connector.
On the DM-D (DM-D500 etc...) which has DIP switch to select Y-type connection, confirm that the DIP
switch has been set “Y-type connection: Enable.”
