UB-U09 Developer's Guide
Confidential
(*1) If pin 6 (DSR) is left unconnected, TM printer DIP switch must be set to “disable reset via pin 6.” This setting, in
combination with the setting of jumper JP2 on the UB-U09, causes the printer to be continually reset. Table 1-2
shows the relationship between jumper JP2 on the UB-U09 and “disable reset via pin 6” setting on the TM printer.
(*2) To reset the TM printer through the interface, the reset signal can be applied to pin 6 or pin 9.
