Specifications The UB-U90, which has been developed for EPSON TM Printers, has serial and USB interface functions. You can switch between the functions by using the USB/Serial switching located on the front of the UB-U09.
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.
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.

Even when the power switch is off, voltage is present at some points on the circuit board. Changing components while the power unit is connected can cause damage to the UB-U09 and the printer. ❏ A grounded wrist strap should be worn during installation to avoid damage from static electricity.
Confidential Package Contents The following items should be included in the UB-U09 package. You can get a locking wire strain relief separately by using the part numbers in the brackets. ❏ UB-U09 ❏ User’s Manual ❏ Locking wire strain relief <1061268>...
Jumper Settings The UB-U09 has a jumper: JP2. JP2 selects the function* of pin 6 (DSR) of the serial connector. (*) Refer to Printer Reset in Chapter 4 for a description of the functions of pin 6 (DSR) of the serial connector.
1. If an interface circuit board is already installed in the TM printer, remove it. Re-use the screws when installing the UB-U09. Install the UB-U09 using these screws. 2. Install the UB-U09 in the TM printer, and tighten the screws. Install the UB-U09 to using two screws. 2-4 Installation...
Serial Interface Cable 1. Confirm that the printer and host computer are turned off. 2. Connect the cable to the serial interface connector on the UB-U09. Note: Connect cables that have a smaller shell than the size indicated in the Figure 2-3. If the shell size is bigger, it may not be connected.
2. Hook USB cable through the locking wire strain relief to keep them in place. 3. Insert the square connector end of the USB cable into the upstream connector of the UB-U09. 4. Insert the opposite end of the USB cable into the downstream connector of the host computer.
