1-16 Technical Information
Note that the COM2 port is factory set for IrDA data transfer and must be reset to
"Standard" for serial port transfers. See Section 2, Setup and Operation, for information on
resetting the port through Setup.
Serial interface specifications include:
n
Baud rate up to 19.2 KB per second
n
Word length - 5, 6, 7, or 8 bits
n
Stop bit - 1, 1.5, or 2 bits
n
Start bit - 1 bit
n
Parity bit - 1 bit (odd parity or even parity).
Serial interface signals are output through the system board's 9-pin, D-subconnector. The
connectors are located at the rear of the system unit. Pin locations for the serial interface
connector are shown in Appendix A.
Infrared Interface
The I/O controller incorporates an infrared interface that provides two-way wireless
communication through the IR window (port) on the front of the system. The interface uses
infrared as the transmission medium instead of a traditional serial cable.
The IR port permits transfer of files to or from portable devices such as laptops and
personal digital assistant (PDA) products using the pre-installed Puma TranXit applications
software or other software supporting IrDA data transfer. The port supports data transfers
at 115 Kbps from a distance of 1 meter (3 feet 3 inches).
The IR port uses the system's COM2 serial port to transfer data. The port shares registers
and function logic with COM2.
POWER SUPPLY
The power supply is mounted inside the system unit. It supplies power to the system board,
option boards, diskette drives, hard disks, keyboard, and mouse. A fan inside the power
supply provides system ventilation. The power supply provides 200 watts. Connector
locations are in Appendix A.
DISKETTE DRIVE
Up to two diskette drives are supported in the system. The installed 3 1/2-inch diskette
drive is connected by a single ribbon cable with two drive connectors. The diskette drive
cable plugs directly into the system board. Connector locations are given in Appendix A.
