Default setting
1)
Firmware version 06 or higher: Receiving DMX packets possible
2)
Activation of flow control RTS/CTS is only possible for "RS-232" mode;
3)
Flow control RTS/CTS with lead/follow-on time possible with firmware version 03 or higher.
4)
Activation of flow control XON/XOFF is only possible for "RS-232" and "RS-422 full-duplex"
modes.
5)
Depending on baud rate, bus system and cable type (use of a twisted-pair cable is
recommended)
6)
A twisted-pair cable must be used in "DMX" mode.
