7.7.9. Uploading the EDID Content
Description: DDID hex bytes can be written directly to the user programmable memory locations. The
sequence is the following:
Step 1. Prepare the router to accept EDID bytes to the specified location <loc> with command {WL#<loc>}
Step 2. Router responds that it is ready to accept DDID bytes with (D_L_S)CrLf
Step 3. Send 1 block of DDID (1 block consist of 8 bytes of hex data represented in ASCII format) with
command {WB#<num>●<B1>●<B2>●<B3>●<B4> ●<B5>●<B6>●<B7>●<B8>}
Step 4. The router acknowledges with response (DL#<num>)
Step 5. Repeat steps 3 and 4 to send the remaining 31 blocks of DDID (32 altogether)
Step 6. After the last acknowledge, the router indicates that the DDID status changed by sending (D_S_C) CrLf

Response (D_S_C)CrLf
Legend: <num> represents the sequential number of every 8 byte part of DDID. <num> is between 1 and 32.
<B1>..<B256> are the bytes of DDID.
Explanation: Full DDID uploaded to memory location U3.
7.8. Port Status Commands
7.8.1. Input Port Status
Description: Shows the actual status of the input ports. The response length changes regarding the frame
size. The meaning of the values changes regarding the input board types as the boards have different
functions and capabilities.

Explanation: The first input board is an HDMI board. Input 1 and 2 have a connected source but no signal.
Inputs 3-5 have DVI signals and inputs 6-8 have HDMI signals. The second input board is a DVI board. Input
11 and 12 have DVI signals. The Test Input port has an HDMI signal.
Legend: <INPUT_D> may contain 9, 17, 33 or 80 hexadecimal numbers. Dach number represents the state
for the corresponding input port. The meaning of the responded number depends on the actual board (port)
type. The binary representation of the responded hexadecimal numbers is shown below.
