If the unit passes the internal port test, next perform the I/O test. Use

or most computer parts stores) to connect the 9-pin serial output port
of a computer to the 25-pin serial RS-232-C port, as shown in Figure

Avoid using a USB converter cable; test results have shown this not
to be dependable.
Open a terminal emulator program such as HyperTerminal™ (©Hil-
