There are two methods for updating the 4K Ultra HD ELR-POL Extender w/ RS-232,

Ethernet, and 2-way IR. The recommended method is to update both units at the same

time by leaving the Sender and Receiver unit connected. Updating the Sender unit will

update the Receiver unit (or vice versa). The second method is to update the Sender and

Receiver unit separately.

Single Update Procedure

This method is recommended and can be used in situations where disconnecting the

system is impractical or difcult. The power supply must be connected to either the Sender

or Receiver unit. The update procedure can take place at the Sender or Receiver location.

1. Download the latest rmware here: http://www.gefen.com/support/download.jsp

2. Extract the contents of the .zip le to the desktop on your computer.

3. Disconnect the power supply from the Sender (or Receiver) unit.

4. Set the following DIP switches on the Sender and Receiver units:

► Sender unit

Set DIP switch 4, on the bottom of the Sender unit, to the ON position:

► Receiver unit

Set DIP switch 1, on the bottom of the Receiver unit, to the ON position:

5. Connect the included RS-232 cable between the Sender (or Receiver) unit and the

computer.

6. Launch a terminal emulation program. In this example, we will be using Windows®

Hyperterminal.
