WARNING
Any or all of the serial ports may be configured for 5, 12 or 24 volts on pin 9 of their
respective D-type connector. This can result in damage to peripheral equipment if the
incorrect voltage is selected. For example if a modem is connected to a port configured for
24 volts the modem will almost certainly be destroyed. It is therefore imperative that the
voltage selected is suitable for the device attached. It is also important to remember that
the industry standard connector for a RS232 serial port is a 9 pin D-type plug, and as pin 9
can be powered it is physically possible to short out pin 9 to either pin 5, 8 or the chassis.
This will almost certainly result in serious damage to the motherboard and possibly to the
peripherals as well. If either selecting the wrong voltage or removing the connectors while
the devices are powered damages ANY peripheral device, the DigiPoS Retail Blade™ or
the Retail Blade™ Host, a charge may be applied by DigiPoS Systems for any repairs
necessary.
