CHAPTER 5: SELECTING DIPSWITCH SETTINGS

The 232SPS2 is set up using an eight-position dipswitch. In order for the 232SPS2 to function properly, it must be set up to match your system's requirements. The following parameters on the 232SPS2 are set on the dipswitch: converter direction, baud rate, flow control, number of data bits, and the type of parity. Each of the parameters are briefly described below. For specific parameter settings, refer to Table 5.1.

Converter direction - Can operate as a parallel to serial converter or as a serial to parallel converter. The direction is set by dipswitch position 8.

Baud rate - Can be set from 1200 to 115.2k baud. The baud rate is determined by dipswitch positions 1-3.

Flow control - Can be set for DTR control or XON/XOFF control. The type of flow control used is determined by dipswitch position 4.

Data bits - Can be set for 7 or 8 data bits. The number of data bits is determined by dipswitch position 5.

Parity - Can be enable or disabled by dipswitch position 6. If parity is enabled, dipswitch position 7 determines whether the parity is even or odd.
