Optical Communication Unit Power Requirements
Use the AC adaptor that comes with the Optical Communication Unit to power it. Be
sure to connect the AC adaptor to the Optical Communication Unit before starting a
data communication operation with a Pocket PC Terminal. Power is supplied to the
Pocket PC Terminal from the Optical Communication Unit.
Using the Optical Communication Unit
1.Plug the AC adaptor into a wall outlet.
2.After confirming that the Optical
Communication Unit is turned off, plug the AC
adaptor cord into the AC adaptor jack on the top
of the unit.
3.After confirming that both the Optical
Communication Unit and your computer are turned off, use an RS-232C cable (DT-
881RSC, DT-882RSC, DT-883RSC, DT-887AX) to connect the RS-232C interface
on the top of the Optical Communication Unit (remove the interface cap) to your
computer.
•Leave the interface cap in place if you do not plan to use the RS-232C interface.
4.Turn on the Optical Communication Unit and your computer.
•The power indicator on the Optical Communication Unit should light red at this time.
5.Mount a Pocket PC Terminal onto the Optical
Communication Unit, making sure the IR port on
the side of the terminal is in contact with the IR port
of the Optical Communication Unit. This should
cause the power indicator on the Optical
Communication Unit to turn green and the charge
indicator to light red, indicating that charging has
started.
