Step 12: Connect the Serial and Parallel Devices

If you have a parallel device (such as a printer), connect it to the parallel connector.
If you have one serial device, connect it to the serial connector S1. If you have an
ASCII terminal, you must connect it to the serial connector S1. An additional serial
device can be connected to the S2 connector.
Two 9-to-25-pin serial converters are optional with your system unit to increase serial
device compatibility.
