PST-7000 series user’s manual – BRIEF INTRODUCTION

VGA Display Port

The VGA port built into the PST terminal departs from the industry norm in

that it has provision to feed 12 volt dc power to the monitor inside the VGA signal

cable. This may cause permanent damage to any other monitor not designed to

accommodate this facility. Please only use the PST monitors with the PST equipment.

If you have any doubt please consult your dealer.

(Note: 12 volt DC power is available on pin 9 of the VGA connector and is supported

by the UPS function.)

(Note: The 10” color monitor uses the AC outlet of power supply unit and is therefore

not supported by the UPS function)

The video memory of this port shares the system memory. The size shared for

video memory can be set in the system CMOS setting to match the user’s application.

It is known that to enable an extended dual display mode requires a video memory of

8 MB.

Customer Display

The customer display connector (marked as VFD) must always be occupied

either by the VFD terminator plug (as supplied) or by one of the family of Posiflex

customer displays. Without this provision the COM1 port and the cash drawer control

may fail to work correctly.

The customer display port of PST system utilizes a hardware handshaking

signal internally selectable between CTS and DSR in RS232 through jumper setting

inside the system. Such design flexibility in the PST system makes the Posiflex

customer display the most convenient companion for application software.

Serial Port – COM1

COM1 serial port must always be occupied by a suitable serial device or

COM1 terminator (as supplied). If this port is left vacant or connected with something

like a mouse the customer display port and the cash drawer control may fail to work

correctly.
