To create/edit an EDID using EDID editing commands:
1. Establish a session with the generator using either HyperTerminal over a serial
connection or Telnet over an Ethernet LAN. See “ Establishing a terminal session with
the generator ” on page 31 or “ Establishing a Telnet session with the generator ” on page
34.
2. To create a new EDID, follow these steps:
a. Create a new EDID file by entering the following command:
DIDN filename
b. Define EDID structure content using EDID edit commands. The following example
shows how you can create EDID content:
DIDB // begins an edid editing session
XDID 0 80
00FFFFFFFFFFFF005A63118F01010101130D010380221B782A4706A55C47

DIDE // ends an edid editing session
Note: The EDID edit buffer commands are new with Release 2.3.0.
c. Save EDID file to the generator by entering the following command:
DIDS // saves the edid
3. To modify an existing EDID (stored on the generator), follow these steps:
a. Load an EDID from the 882’s internal file system:
DIDL filename
Where filename is the name of a file in a the default directory identified by DIDP .
For example, the command below loads an EDID from the default EDID path.
DIDL myedid1
If the EDID you want to load is not in the default path, you can either list the path
explicitely on the
DIDL command line or change the EDID path with DIDP . For
example, the command below loads an EDID from a different directory in flash
memory.
DIDL /tffs0/library/userdata/myedid1
b. Modify EDID structure content using EDID edit commands. The following example
shows how you can modify EDID content:
DIDB // begins an edid editing session
XDID 19 A E88A82A0564796240F48 // edits EDID at 19 for 10 (0x0A)
bytes
DIDE // ends an edid editing session
