Serial Port

While the power of ShieldPRO is ON, do not connect or disconnect the serial cable. Failure to follow this
instruction may cause ShieldPRO to operate improperly.
ShieldPRO has a RS232 serial port which provides connection to devices via a serial cable.
To connect a serial device to ShieldPRO, follow the procedure below:
1. Confirm that [Enabled] is selected in item "Serial Port A:" in BIOS setting (See "6 Setting
BIOS" for details).
2. Confirm that the power of ShieldPRO is off.
3. Insert the cable of a serial device to the serial port on ShieldPRO.
Some Operating Systems may limit serial features.
4. Turn on the power of ShieldPRO.
ShieldPRO does not support serial devices that require power from the serial port. Use serial devices that
source external AC power or their own batteries.
