CAUSE: Port configuration.

SOLUTION: Match the baud rate, word size, stop bits, parity and handshaking between the host device and the host port.

CAUSE: Port connection.

SOLUTION: Be sure host device is connected to host port of the H-Series multiport (the highest numbered port).

CAUSE: Software.

SOLUTION: Use dumb terminal or a computer running a terminal emulation program: TERM supplied by BayTech or another communication program.

CAUSE: Bad serial port on host computer.

SOLUTION: Try a different serial port or host device.

PROBLEM: GARBAGE DATA

SYMPTOM: MISSING CHARACTERS

CAUSE: Incorrect cable type or XON/XOFF setting.

SOLUTION: Check hardware handshaking lines in the cable. The H-Series multiport comes standard with DCE serial ports. The output handshake line is CTS (Clear To Send) and the input handshake line is DTR (Data Terminal Ready). CTS (Pin 5) should be connected to the host/peripheral device's input flow control line and DTR (Pin 20) should be connected to the host/peripheral device's output flow control line.

If using XON/XOFF handshaking, verify that both Tx and Rx are connected in the cable. Also verify that XON/XOFF handshaking is enabled on the H-Series multiport.
