USING THE CUSTOMER DISPLAY
COM PORT SELECTION
This series of customer display is designed to serve in Posiflex POS
systems with RS232 interface. It is advisable to well study the I/O port
availability of the host system before determining which COM port to be used.
When a RS232 (serial) interface model of PD-201 is used, the jumper
on main board of the host system must be modified to supply power to the
COM port designated for PD-201. Whenever the RS232 interface PD-201 is to
be removed from the host system, consequently the jumper has to be changed
back to neutralize the power support in the COM port, otherwise damage
could occur!
COMMAND MODE SELECTION
The PD-201 will always be in the Epson command mode at power on.
It can enter or exit the PST command mode through software command.
