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.
