-pair on the CAT5 cable. These are configured differently by a front-panel setting, or may include an
internal hardware option-module.
MVII-DVI-TX-A:
o
Supports L+R summed audio (user-configuration setting).
MVII-DVI-TX-S:
o
Supports 2-wire RS-232 serial in simplex mode (user-configuration setting).
MVII-DVI-TX-232:
o
Supports 9-wire RS-232 serial (simplex, or duplex with hardware handshaking).
o
Contains the (232) option module.
MVII-DVI-TX-SA:
o
Supports 3-wire RS-232 serial (simplex or duplex), and true stereo audio.
o
Contains the (SA) option module.
MVII-DVI-TX-SAP:
o
Supports 3-wire RS-232 serial (simplex or duplex), and true stereo audio.
o
The serial feature is POLLABLE, so that multiple receivers on a daisy-chained link can be
addressed individually for display control or status-query.
o
Contains the (SAP) option module.
Note:
A user-configuration setting allows either the (A) or (S) versions to support digital S/PDIF audio.
The option module (232/SA/SAP) is a factory-installed option. However, a field upgrade to a (232), (SA) or (SAP)
version is possible. It will require some minor technical skill to install the module.
Please contact Magenta
Research for information and assistance for these upgrades.
Note that for each DVI-TX version above, the accompanying receiver device (MV500, AK600, AK1200, XR2000,
etc.) must be similarly configured.
For more specific information on MultiView™ receivers, please refer to the user-guide provided with your desired
