Writing Edid Data To A Dvi Or Hdmi Input Connector - AMX Optima Instruction Manual

Using Cable Adapters
If your laptop has an HD-15 (VGA) port, you can use a DVI-to-VGA cable to connect the laptop's
HD-15 video port to a DVI cable attached to a destination device's DVI port. Alternatively, use the
following combination of adapters with a DVI-D cable to connect the laptop to the destination device.
The setup of adapters and DVI-D cable in FIG. 102 passes EDID information but not video signals.

Writing EDID Data to a DVI or HDMI Input Connector:

To write EDID data to the EDID chip for a DVI or HDMI input connector:
1.
Attach a null modem serial cable without hardware flow control to the Control port (DB-9) on the
Optima. Use a serial cable that matches the pin diagram in FIG. 103 for RS-232. The Control port
uses pins 2, 3, and 5 only.

2.
Attach the open end of the serial cable to the PC that the EDID Programmer will be opened on.
3.
If necessary – From the Communication menu, select Change Settings
to change the baud rate for the PC's serial port, which must match the
baud rate for the Optima. The recommended (default) settings for serial
communication with an Optima are in the table to the right.
4. Apply power to the enclosure.
5.
On the PC, open the EDID Programmer.
6.
For the Target Device, select the Matrix Switcher option.
7.
Click the Query AutoPatch Device button to obtain the XNNet address
from the enclosure.
Note: If your laptop has an HD-15 (VGA) port, see "Using Cable Adapters" on page 158 for
information on connecting an HD-15 (VGA) port to a DVI port.
8.
Attach a DVI or HDMI cable to the PC using the PC's spare monitor port (if the PC has a DVI port
and the Optima input is HDMI, use a DVI-to-HDMI cable adapter).
9.
Attach the open end of the DVI or HDMI cable to the DVI or HDMI input connector on the Optima
that requires programming.
10. Save the board's EDID default as a backup (assumes the board has factory default EDID
programming).
