If the acid comes in contact with eyes, rinse eyes with large amount of clean water and see a doctor immediately. A larger external battery may be connected to give an extended operation.

Printer DC Power Supply

This power supply is designed to support a Posiflex POS printer via the right cable. Careless use of it will cause permanent damage.

VGA Display Port

The VGA port in the PST terminal supports a 12 volt DC power to the monitor inside the VGA signal cable. This may cause permanent damage to any other monitor not designed to use this facility. Please use only a designed monitor with the PST equipment. Consult your dealer if you have any doubt.

(Note: 12 volt DC power is available on pin 9 of the VGA connector and is supported by the UPS function if the power management option is installed.)

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 (when power management option is installed) may fail to work correctly.
