MultiView™ II DVI-TX Installation and User Guide 7
3.4.2 Auxiliary Signal support: (232) version
The DVI-TX-232 comes equipped with an internal hardware (232) option module, enabling full-duplex RS-232
serial. This includes hardware handshaking signal support. Note that the (232) module itself does have
some
user-configurable settings which must be selected by internal jumpers (not through the front-panel buttons). It is
important to set these internal jumpers correctly for your specific application. See Appendix-B.
 Simplex or Duplex RS-232 support.
o Provides simplex serial data to single or daisy-chained multiple receivers.
o Provides duplex serial data for point-to-point links (1 transmitter  1 receiver).
o Data is transmitted and received using “broadcast” mode.
o Receivers are not individually addressable.
o RS-232 interface supports a 9-wire interface: TXD/RXD/RTS/CTS/DTR/DSR/DCD/RI/GND.
 Handshaking modes depend on (232) module configuration. See Appendix-B.
o Baud rates up to 115,200 are supported.
 Available baud rates depend on (232) module configuration. See Appendix-B.
 Audio: No audio is supported when the (232) module is installed. The AUX-I/O connector on the DVI-TX
is ignored.
In applications where a DVI-TX-232 transmitter is routed through a DA (Distribution Amp, such as a MultiView 9D
for example), or a Mondo (or other) video switch, the (232) module will provide simplex serial (TX-only) and
transmit-direction handshaking signals (RTS/DTR). In this configuration, all receive-direction signals
(RX/CTS/DSR/DCD/RI) are ignored.
3.4.3 Auxiliary Signal support: (SA) version
The DVI-TX-SA comes equipped with an internal hardware (SA) option module, enabling full-duplex RS-232
serial (no hardware handshaking signals) and stereo audio. Note that the (SA) module itself does not have
any
user-configurable settings.
 Simplex or Duplex RS-232 support.
o Provides simplex or duplex serial data, even with daisy-chained receivers.
 For duplex support with daisy-chained receivers: It is required that the display
devices have their own “addressing” capability.
o Data is transmitted and received using “broadcast” mode.
o Receivers are not individually addressable.
o RS-232 interface supports a 3-wire interface: TXD/RXD/GND.
o Baud rate is fixed at 9600.
 Audio: L/R true stereo audio is supported
simultaneously with serial data.
Note that in cases where a DVI-TX-SA transmitter is routed through a DA (Distribution Amp, such as a MultiView
9D for example), or a Mondo (or other) video switch, the (SA) module will provide simplex serial (TX-only) and
audio. In this mode, receive-direction serial data (RX) is ignored.
