To switch between RS-232C and RS-422/485, set the DIP-SW and JP under the PCI expansion unit connector cover.
CAUTION
For TxD, RxD, and RTS, RS-422A/485 pin assignment has even-numbered pins for positive and
odd-numbered ones for negative. For CTS, however, even-numbered and odd-numbered pins are
assigned for negative and positive, respectively, in contrast with other signals. This is not a
description error.
