CHAPTER 7: Using the Serial Ports

CAUTION!

Serial cabling in excess of 50 feet (15.2 m) should be routed with caution. The maximum cable length depends upon the construction of the cable and its routing. For extended runs, shielded cable should be used. Avoid routing near fluorescent lights, air-conditioning compressors, or machines that may create electrical noise. If you experience a lot of data errors, use shorter cables. The Matrix ServSwitch’s lowest data rate is 9600 bps; it cannot be lowered any further to alleviate this problem.

7.2 The Serial Options Menu

Once you have connected the dedicated terminal or computer running a terminal emulator to one of the Matrix ServSwitch’s serial ports, make sure the data rate of the terminal or emulator is set to match that of the Switch port. (If you’re not sure how to do this for your emulator, refer to its manual or online help for instructions. If you’re not sure whether the serial port on the Switch is set to operate at 9600 bps or 57,600 bps, try 9600 bps first. That is the factory-default rate, and should be the rate that all of the serial ports on new Matrix ServSwitches start out using.) Then turn on or cycle power to the Switch. This message should appear on your screen:

Hit the spacebar within 5 seconds to get serial options menu.

If garbage characters appear instead, your terminal or emulator is set to the wrong data rate; switch to the other one and cycle power to the Switch again. When the message appears as it should, press the spacebar. The serial options menu will appear after the Switch finishes displaying its power-up diagnostic messages. This menu enables you to manipulate certain configuration settings and (if you’re using a computer rather than a terminal) to perform flash upgrades. The subsections on the following pages detail the serial menu options:

1.Change starting cpu number..........1

2.Change the serial port baud rate....[current rate, either "9600" or "57,600"]

3.Receive new main program or kernel from serial port (this card only)

4.Send this unit’s main program to other units

5.Send this unit’s Kernel to other units

6.Reset Configuration data to factory defaults (this card only)

7.Save changes made in 1 and 2 (this card only)

8.Exit (restart the unit)

Enter choice
