    A switch on the PIO board (see Figure 56, page 88) changes the communication settings between RS-232 and RS-422. Your computer and the Workhorse II must both be set to the same communication setting. Use the RS-232-to-RS-422 converter if the Workhorse II is using RS-422 communications and your com- puter only has an RS-232 COM port.
