Step 3: Install the 691
To mount the 691 in a rack, use an RK-1 rack adapter. Alternatively, attach the rubber feet to the underside of the 691 and place it
on a table.
Step 4: Connect the inputs and outputs
Always switch OFF the power on each device before connecting it to your 691. For best results, we recommend that you always use
Kramer high-performance cables to connect AV equipment to the 691.
Always cross-connect the fiber connections, Rx OUT to Tx IN and Rx IN to Tx OUT, as transmission is carried
on simplex fiber strands.
To install the OSP SFP+ transceiver:
1. Make sure the bail is pushed up, in the closed position.
2. Insert the OSP SFP+ transceiver into the relevant optical device SFP+
slot and push it in until it clicks.
Remove the protective cap and store it in a safe place for future use.
Warning: Connecting the OSP SFP+ connector to an LC(APC) fiber
connector may cause poor performance and damage the connector!
