10 I-Class
3.1.1 Communications
Following power-up (or after a period of inactivity), interface port selection occurs
automatically upon detection of valid data. If the incoming (received) data flow stops and
the Host Timeout Value (see Section 4.2.6) is exceeded, partially received formats will be
ignored and the port detection process repeated.
 Notes: 1) To change an active port immediately, cycle the power OFF and ON.
2) For alternate data processing options, see SYSTEM SETTINGS / INPUT
MODE - Section 4.2.5.
DMXNetII Network Interface Card / DMXrfNetII Wireless Network Interface Card
The optional network interface has several menu-selectable modes; see Section 4.2.6 or
refer to the manual provided with the option.
Parallel Port
The parallel interface has two menu-selectable modes of operation:
•
Unidirectional mode is forward channel communication and requires a Centronics
cable with a 36 pin male connector.
• Bidirectional mode is IEEE 1284 Compliant, using forward and reverse channel
communications and requires an IEEE 1284 cable with a Centronics
36 pin male
connector.
Serial Port
The serial interface supports RS-232C, and if equipped optional RS-422 communications.
The serial interface has menu-selectable settings that must match the host computer’s
settings; see Section 4.2.6. In addition to the port settings, serial cable wiring must
have specific pin connections for proper data flow; see Section 7.3.
USB Interface Card
The optional USB Port is plug and play interface, operating transparently and without menu-
selectable settings or modes.
WARNING
The USB Port is a device-end only connection. Never connect a keyboard,
mouse, modem, etc. to this port; damage can result.
