WIRELESS LAN (OPTION)
When the wireless LAN option is ordered with the PB system, this
option is already installed in the delivery inside the back cable cover with its
cable connected to one of the USB port. This cable must be disconnected
first if installed whenever the back cable cover is opened for any operation.
CUSTOMER DISPLAY (OPTION)
When the PB series is ordered with the customer display option, the
customer display together with the pole for installing them to corner of back
cable cover will be delivered in separate package from the system unit. Please
follow the Installation Guide in package of the option. The customer
display will occupy one COM port or one USB port. However, before
installing an integrated customer display option on a PB system, please have a

in the COM port used if the pole display is of RS232 interface and to
neutralize the power supply once the customer display is to be removed from

programmable keyboard with the cable fit into the strain relief groove or in
between the PS/2 KB port of the system unit and the Posiflex programmable
keyboard. The only consideration is that in programming stage of the
programmable keyboard, nothing (including the barcode scanner) should come
