Basic Operation

The Options port on the rear panel of every extender operates as a serial connection that can either:

•

Be used to update the firmware of the unit

•

Provide an RS232 serial connection that is passed between the transmitter and receiver.

When the extenders are not in upgrade mode, they can be used to transfer serial data between them at rates

up to 115200 baud. When serial devices are attached to the options ports on the transmitter and receiver, the

units transparently convey the signals between them and no serial configuration is required.

The LongView™ extenders are flash upgradeable. The same upgrade file is used to upgrade both the

transmitter and receiver units, but are upgraded separately.

WARNING: During the upgrade process, ensure that power is not interrupted as this may leave the unit in

an inoperable state.

To upgrade the extenders:

1. Download the upgrade file from

Downloads/kvm-switches/KVM-Extenders/Pages/default.aspx.

2. Connect a serial cable between the computer and the options port of the extender to be upgraded.

3. Using a straightened-out paper clip, press and hold the recessed reset button on the front panel until the

indicators begin pulsing.

4. With the unit in download mode, transfer the upgrade file using an XMODEM file transfer via any

terminal emulator program. Use the following settings: 115200 baud, 8 bit word, no parity, 1 stop bit

(8N1) and no flow control.

After the download completes, the extender firmware is upgraded. Once this process is complete, the unit will

reboot.

Two DisplayPort ports are provided on the rear panel of the transmitters. When using high resolution video

displays, it is important that the video bandwidth requirements are within the capabilities of the port to which

they are attached. The bandwidth available on the two ports on the receiver unit can be different and are

greatly affected by the mode in which the extender system is running. Please see the release notes for details

about which high and low rate modes and resolutions are supported.

The link capacity between the transmitter and receiver is checked periodically to determine which rate mode

can be supported. The checks are generally performed when the units are powered on, when the main CATx

link is established, if cables are disconnected or if the CATx link is lost. See

information on selecting the rate mode.
