RS-232↔485/422 CONVERTERS

NOTE

When the jumper W9 (CTS) is in the ON position and jumper W15 is in the A-B position, the RS-485 driver is always turned on to enable transmission of data. Therefore, half-duplex transmission cannot be performed. See Section 3.1.5 for an explanation of the RS-485 driver.
