is not required for a Link Adapter connected to a Serial Communications
Board or Unit because power is supplied from pin 6 of the connector.
4. The maximum cable length for RS-232C is 15 m. The RS-232C standard,
however, does not cover baud rates above 19.2 Kbps. Refer to the manual
for the device being connected to confirm support.
The connection examples in the remainder of this section show only the basic
connection diagrams. We recommend that appropriate noise countermea-
sures be taken in actual applications, including the use of shielded twisted-
pair cables. Refer to 3-4 RS-232C and RS-422A/485 Wiring for actual wiring
methods.
