Notes:
1.
These three settings are commands and should not be used as EDID settings. When the switch is
set to these commands, the EDID remains as the last valid EDID setting until another EDID setting
is chosen.
2.
The USER 1 EDID Memory can also be programmed using the appropriate RS232 command, see
the RS232-CTL Commands section for details of this command.
3.
The Copy from Output 1 switch setting reads the EDID data from the display device connected to
the HDMI output to the User 1 EDID memory of both inputs.
4.
The Copy from 1
st
Connected Output switch setting will copy the EDID data from the first display
device that is connected to the SY-HDBT-231 to the User 1 EDID of both inputs. This can be from
either the HDMI output or any of the HDBT outputs.
Cascade Mode
Cascade mode can be enabled/disabled via RS232 commands (SET CAS EN, SET CAS DIS), using
RS232-CTL port. This may speed up the overall system switching speed when several devices
are cascaded together (such as HDBT-231 to MSUHD88 to Apollo 4K to…).
Be sure to wire the RS232 connections correctly when using D-type connectors, as given in the
following table:
