To change these default settings please see Initial Setup & Operation via Baluns section below. 1. Insert cables into card slots 1 through 16 Slots 1-8 are labeled Rx, and are Input Card Slots 1-8. Slots 9-16 are labeled Tx, and are Output Card Slots 1-8. Connect your source components to the Input cards Connect your displays to the Output cards Power up all sources and displays 2. Establish an Handshake for Each Source Push the left selector to access the Main Menu choices Using the left selector, scroll to the 7-EDID Setup Menu Press the right selector to navigate to the EDID sub-menus With the left selector, scroll to the Input source you wish to copy the EDID to Using the right selector, scroll to the or Output you wish to establish an handshake for, or select a Default EDID 01-08 from the EDID library (see pg.10) Press the right selector to set the Handshake for that combination Continue this procedure for all Inputs The EDID control and input set up is stored in a non-volatile memory back up and is only required during initial set up or when a new display or source is added to the system. Establish a default handshake for ALL Inputs: Using the 7-EDID Setup Menu, select ALL Inputs and scroll to the Output number you wish to copy the EDID from (, or a Default EDID setting) and press the right selector 3. Switching via Front Panel Push the left selector to access the Main Menu choices Using the left selector, scroll to the 1-Video Switch Menu Press the right selector to navigate to the Video Switch sub-menus Using the left selector, scroll to the Output you wish to select Using the right selector, scroll to the Input you wish to select Finally, press the right selector to make the switch 4. Sending your output via KD-BBRX Receive Balun(s) Both and Outputs are active on all Output Card Slots, therefore no configuration is necessary to activate the Output for each Tx Card Slot. 5. Sending your source via KD-BBTX Transmit Balun(s) Set dipswitch #2 of the KD-BBTX Balun to DDC in order to establish a proper handshake Configure the appropriate Input Card Slot to activate its input using the 6-Video Input Setup Initial Setup & Operation via Baluns When using Key Digital Baluns (RX/TX) you must use the following procedure to correctly format both the baluns and HDMS8x8 matrix switcher for correct operation. NOTE: Slots 1-8 are inputs, slots 9-16 are outputs. The KD-BBTX Dipswitch #2 MUST be set to the DDC position. IMPORTANT: Make sure that you power up all baluns, sources and displays. Confirm that you have an active connection on the Balun indicated by the solid red LINK LED. 1. By default, the KD-HDMS8x8 is configured to accept a direct connection. When using a KD-BBTX, you MUST change the input mode from to to enable the switcher to see the /Balun input. Select 6-Video Input Setup from the main menu. Press the right selector to navigate to the sub-menus. Using the left selector, scroll to the Input number you wish to change. Using the right selector, scroll to select and press the right selector to enter your choice. 2. Repeat procedure for any other input where a KD-BBTX is being used. 3. Once you have correctly configured the inputs to accept either and/or /Balun, you need to establish the correct handshake. 4. See previous section on establishing an handshake.
