Some RS422/RS485 transceivers are equipped with Slew-Rate Limit ability. In order to
maintain compatibility with these chips, the Slew-Rate Limit ability must be activated. If
Slew Rate Limit function is activated, communication speed considerably decreases
but instead gives off less emission. When activating the Slew-Rate Limit,
communication speeds must be below 250Kbps.

Initial condition used when opposing RS422/RS485 transceiver does not have the
Slew-Rate Limit function. When the Slew-Rate Limit function is not selected maximum
communication speed is 921.6Kbps. (Max chip speed: 16Mbps)
