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:
Note:
The setup of adapters and DVI-D cable in FIG. 35 passes EDID information but not video
signals.
Writing EDID Data to a DVI or HD-15 RGBHV Input Connector
The instructions that follow cover the situation in which the EDID Programmer is used to write EDID
information to the EDID chip for an input connector on an Epica DGX DVI input board that still has
factory default settings. A DGX HD-15 RGBHV input board can be re-programmed using the same
instructions; use an HD-15 video cable instead of a DVI cable.
To write EDID data to the EDID chip for an input connector:
1.
Attach a null modem serial cable without hardware flow control to the serial port (DB-9) on the
Epica DGX 144. Use a serial cable that matches the pin diagram in FIG. 36 for RS-232.
AMX AutoPatch equipment uses pins 2, 3, and 5 only.
