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.

RS-232 Mode

To configure a port for RS-232 mode, 5 jumpers must be checked. The following settings will configure Port 1 as RS-232.

1.JP1A - must be set in the "232" (left) position.

2.JP1F - all four jumpers must be set in the "232" (left) position.

Jumpers JP1B - JP1E have no meaning in RS-232 mode and may be in either position. Figure 2 shows the jumper configuration to set both ports for RS-232 mode.

Note that the EIA RS-422 Specification labels data lines with an "A" and "B" designator. Some RS-422 equipment uses a "+" and "-" designator. In almost all cases, the "A" line is the equivalent of the "-" line and the "B" line is the equivalent of the "+" line. More information on RS-422 communications can be found in B&B Electronics’ free RS-422/RS-485 Application Note.

RS-485 Mode

To configure a port for RS-485 mode, 9 jumpers must be checked. The following settings configure Port 1 as RS-485.

1.JP1A - must be set in the "422" (right) position.

2.JP1B, JP1C - must be set in the "485" (left) position.

3.JP1D, JP1E - set to match software and installation requirements.

4.JP1F - all four jumpers must be in the "422" (right) position.
