order, the customer display will not be recognized correctly.

. To
mount the ferrite core, put the display module cable into the ferrite core.

TM printer with the Ethernet interface is connected to a network with the Ethernet cable via a
Hub.
Note:
The Ethernet interface TM printer does not accept a customer display (DM-D). Connect the customer
display to a POS terminal or appropriate equipment other than the printer.
Note:
When controlling the printer with OPOS, it is necessary to use exclusive control. Therefore, when using 1
printer with several PCs, it is necessary to take into account application programming whereby a PC that
already has the exclusive right must release it, then another PC must claim it.
