Chapter 5: Communication Jumper Settings

This chapter will cover all of the jumper settings to set your B&B Serial Card for the proper communications that you desire.

CAUTION : Electrostatic Sensitive Device.

Use ESD precautions for safe handling.

High Speed Mode

The 232CC Serial has only two communication jumpers referring to clock speed. High data rates may be obtained with the 232CC cards by placing JP1 or JP2 in the *2 position. This multiplies the clock speed supplied to the UARTs by 2 times to 3.684MHz for Ports 1 and 2 respectively, allowing data rates up to

230.4KBaud. Note that serial software is not aware of the change in oscillator frequency. For example, with JP5 in the *2 position, setting the baud rate to 115.2 KBaud in software will result in a actual baud rate of 230.4 KBaud. It is also important to realize that simply increasing the baud rate may not increase actual throughput. Often, due to the computer’s inability to respond to interrupts quickly enough, there will be large idle spaces between characters. Increasing the baud rate to this point will reduce allowable cable length, and increase the potential for data errors.
