Operating the DisplayPort Detective Plus
EDID Programming
Uploading an EDID file to a EDID Bank
In some instances, uploading the EDID directly to the local input is not desired. In this
case, an EDID can also be uploaded to the desired EDID bank using the
#loedidtoba
command. The EDID file must be in binary (
.bin
) format.
1. Connect the
DisplayPort Detective Plus
to the computer using a USB-to-Mini USB
cable. The USB connection will power the
DisplayPort Detective Plus
.
2. On the PC, launch a terminal-emulation program. We will be using Windows®
Hyperterminal to illustrate this example.
Refer to
Using the Virtual COM Port
for more information on terminal communication
settings.
3. Type and enter the following command line:
#loedidtoba param1
where
param1
is the EDID bank where the EDID file will be uploaded. The file type
must be binary (
.bin
).
In this example, we will upload an EDID file to EDID bank 3:
#loedidtoba 3
4. After executing the command, the terminal program responds with the following:
Waiting for the file to be sent ... (press ‘a’ to abort)
5. Open the
Transfer
menu and select
Send File...
6. Click the
Browse...
button to select the EDID file.
7.
Select
Ymodem
as the sending protocol.
8. Click the
Send
button.
9.
After the EDID has been uploaded to the EDID bank, the following will be displayed:
File: viewsonic.bin, Size: 128 Bytes
Download successfully
Note in the example, above, the file size is displayed as 128 bytes. This number will
vary depending upon the size of the EDID that is uploaded. The two most common
file sizes are 128 and 256 bytes.
