DGX HD-15 TX using an HD-15 cable.
DGX DVI TX
The instructions that follow can be adapted to cover the situation in which the EDID Programmer is used
to write EDID information to the EDID chip for the Video Input connector on a previously
unprogrammed DGX DVI TX. Use a DVI cable instead of an HD-15 cable. A DVI to HD-15 adapter
may be necessary depending on the PC (see “Using Cable Adapters” on page 53).
Note:
If the system contains an RX, the RX does not need to be connected, powered up or placed in
a specific Scaling option during the following process.
To write EDID data to the EDID chip on the TX:
1. Connect the HD-15 video cable (if necessary, use a cable adapter; see page 53) to the PC using the
PC’s spare monitor port.
2. Connect the open end of the HD-15 cable to the Video Input connector (HD-15) on the TX.
3.
Apply power to the TX.
4.
Flip the TX EDID switch up to the W (write enable) setting. (The EDID LED on the front of the TX
illuminates solid green.)
5. If not already open, open the EDID Programmer on the PC (for an illustration of the interface,
see page 54).
6.
For Target Device, select the Accessory Module option.
7. Save the TX’s EDID default as a backup (assumes the TX has no previous EDID programming) .
