MultiView™ II DVI-Tx Installation and User Guide 3
1.3.2 Auxiliary Signal support: SAP version
The MVII DVI-Tx-SAP comes equipped with an internal hardware SAP option module, enabling full-duplex RS-
232 serial (no hardware handshaking signals) and stereo audio. The SAP module in the DVI-Tx has no
address-switch settings. However, it is important to check the address-switch settings in the connected
Receiver SAP units (DVI-Rx-1K-SAP, AK600/1200DP-SAP etc.). Please refer to Appendices B and C for
information on setting the address-switches on the Receiver SAP modules.
 Simplex or Duplex RS-232 support.
o Provides simplex or duplex serial data, even with daisy-chained receivers.
o Data is transmitted and received using “broadcast” mode by default.
o If desired, receivers are individually addressable.
o RS-232 interface supports a 3-wire interface: TX/RX/GND.
o Baud rate is adjustable in 9 steps from 1200 to 115K BAUD.
 The factory-default speed is 9600 BAUD.
o Note: The Receiver SAP modules must have their SAP address configured correctly.
 The factory-default setting for all (SAP) modules is address-0. This is the “broadcast”
address.
 Note: All Receiver SAP address configuration changes (via DIP switches, see
Appendix C) should be done before making any cable connections and applying
power.
 Audio: L/R true stereo audio is supported simultaneously with serial data.
o Audio gain/mute settings are under serial control.
 The SAP module provides many additional user-configurable settings, available through the serial port.
Please refer to the SAP-II Programmer’s Guide for additional details.
Note that in cases where a DVI-Tx-SAP transmitter is routed through a DA (Distribution Amp, such as a
MultiView 9D for example), or a Mondo (or other) video switch, the SAP module will provide simplex serial (TX-
only, though the addressable-receiver and stereo-audio features still work). In this mode, receive-direction
serial data (RX) is ignored.
