MultiView™ II XRTx Installation and User Guide 7
3.4.2 Auxiliary Signal Support: (232) Version
The XRTx-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. For more information, see
Appendix-B.
The following table describes features of the RS-232 version.
Table 7: XRTx-232 Features
Feature
Description
Simplex or Duplex
RS-232 Support
Provides simplex serial data to single or daisy-chained multiple receivers.
Provides duplex serial data for point-to-point links (1 transmitter 1 receiver).
Data is transmitted using “broadcast” mode.
Receivers are not individually addressable.
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.
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
XRTx
is ignored.
In applications where an XRTx-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 XRTx-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. The following table describes features of the XRTx-SA.
Table 8: XRTx-SA Features
Feature
Description
Simplex or Duplex
RS-232 Support
Provides simplex or duplex serial data point-to-point, simplex-only in a daisy-chain.
Data is transmitted using “broadcast” mode.
Receivers are not individually addressable.
RS-232 interface supports a 3-wire interface: TXD/RXD/GND.
Baud rate is fixed at 9600.
Audio
L/R true stereo audio
is supported
simultaneously with serial data.
Note that in cases where an XRTx-SA transmitter is routed through a DA (Distribution Amp) such as a
MultiView™ 9D, for example, or a Mondo (or other) video switch, or used with daisy-chain receivers, the (SA)
module will provide simplex serial (TX-only) and audio. In this mode, receive-direction serial data (RX) is ignored.
