PDT 1100 Terminal Product Reference Guide
Using the Optical Interface
The PDT 1100 communicates with other IR communication devices by aligning the IR ports.
Ensure there is nothing obstructing the line of sight between the terminal and target and
keep the terminal and target within 10-80 centimeters or 4-30 inches. The effective IR range
and IR port angle may differ depending upon the target equipment; refer to the equipment’s
user manuals.
Communications Failures
If the data communications transfer fails, move the PDT 1100 closer to the target, or change
the IR port angle and try again. Some types of highly intensive indoor lighting (inverter-
driven fluorescent lights) or direct exposure to sunlight can cause communications failures.
To prevent interference, do not use any TV remote control near the IR communications
system. Refer to
Appendix A, Specifications for communications specifications.
Using the Direct Cable
The PDT 1100 can also be connected directly to a host computer, a modem, or a printer
with the optional RS-232C interface cable.
Note: The terminals’ interface port is not designed to withstand frequent
connecting and disconnecting. If frequent communications are
needed with a host computer that is not equipped with an IR port,
use the CRD 1100 cradle.
