NOTE

The delay settings for W9 apply only to the CTS output of the RS-232↔485/422 Converter. Since CTS is not used when the RS-232↔485/422 Converter is configured as a DTE device, placing jumper W9 in either the 0-, 10-, or 30-msec position will allow the CD input to enable the RS-485 driver. When jumper W9 is in the ON position, the CD input has no affect on the RS-485 driver.
