RS-232 Mode

To configure the port for RS-232 mode, 5 jumpers must be set/checked. The following settings will configure the port as RS- 232:

1.Set four jumpers of JP2 (A-D) to the "232" (left) position.

2.Set JP1 to the "RTS(232)" (right) position.

The remaining jumpers, JP4, are unused in the RS-232 mode and may be in either position. Figure 2 shows the jumper configuration to set the port for RS-232 mode with *1 clock enabled.

RS-422 Mode

To configure the port for RS-422 mode, 7 jumpers must be set/checked. The following settings configure the port as RS-422:

1.Set the four jumpers of JP2 (A-D) to the "422/485" (right) position.

2.Set the top jumper "TX" of JP4 to the “422” (left) position.

3.Set the second jumper "RX" of JP4 to the “422” (left) position.

4.The JP1 Control (SD/RTS) jumper is unused in the RS-422 mode and may be in either position.

5.The bottom jumper "Termination" of JP4 switches the 120Ω receiver termination resistor IN or OUT. Typically this resistor is not used. In some cases using high baud rates and very long cables, termination is needed. See B&B Electronics’ free RS- 422/485 Application Note (available on our websites), Termination section, page 16, for more information. Figure 3 shows the jumper configuration to set the port for RS-422 mode with *1 clock enabled.
