Epson UB-U09 - Interface Cable

1-2 System Preparation Rev. B
Confidential
The maximum transmission speed is 115.2k bps when using a serial interface.
(*) Handshaking, communications speed, data bit length and parity are set by DIP switches on the TM Printer.
Interface Cable
Prepare a serial or USB interface cable according to customer requirements. Note that while the
standard serial interface of the TM printers uses a 25-pin D-sub connector, the UB-U09 uses a
9-pin D-sub connector.
Table 1-1 shows the recommended wiring for the interface cable.
