Chapter 2 Installation Installation This chapter describes the UB-R04 installation. The UB-R04 is an interface board on which is installed the Radio Frequency module for Epson TM printers. The Radio Frequency module is installed on the UB-R04 at the factory. To set up the printer, install the UB-R04 in the Epson TM printer and initialize the UB-R04 to return it to its default setting. Set the PC to be able to communicate with the UB-R04. Then change the setting of the UB-R04 using the setting PC. The UB-R04 can be set by using the dedicated utility EpsonNet Config. Installation Precautions Cautions and Note • Before installing, disconnect the Power Unit from the TM Printer (as well as turning the power switch off ). WARNING Even when the power switch is off, voltage is still present at some points on the circuit board. Changing components while the Power Unit is connected can cause damage to the UB-R04 and the printer. 2 • A grounded wrist strap should be worn during installation to avoid damage from static electricity. • To avoid damage from static electricity when the unit is removed, place it on an static-safe surface such as conductive foam. • Protect the unit from vibration and shock that could damage to the unit. • Do not attempt to wire this product other than as described in this document. Improper wiring could cause damage, fire or explosion. • Never disassemble or modify this product. Tampering with this product may result in injury, fire, or electric shock. Because the default IP address for all the wireless printers is the same, you should power on and configure only one printer at a time. 23
