VigorSwitch V1281 - HDMI Extenders

CYP IP-6000TX & IP-6000RX 4K Extenders

The CYP IP-6000TX Transmitters and CYP IP-6000RX Receivers have been tested and work well with the VigorSwitch V1281.

Setting up the CYP HDMI-over-IP devices to work with the Video Switch requires only a couple of setting changes in the web interface of each CYP HDMI-over-IP device, and one setting change on the VigorSwitch V1281.

When configured, the VigorSwitch V1281 controls which Source (CYP IP-6000TX) is connected to each Output (CYP IP-6000RX) using either the Preset Selection or Source Selection modes.

Other models within the CYP range may also work, but we do not have specific testing information at this time.

The sending of IR (infra red) remote control signals back to the senders is also supported by multiple units simultaneously.

This guide consists of three Sections; the setting changes in Section 1 and Section 2 must be completed before proceeding with Section 3:

2. CYP HDMI-over-IP Setup for VigorSwitch V1281

3. Connecting CYP HDMI-over-IP devices to the VigorSwitch V1281

VigorSwitch V1281 Setup for CYP HDMI-over-IP devices

Sending 4K video across a Gigabit network efficiently requires Jumbo Frames to be enabled on the VigorSwitch V1281, this allows packets larger than 1500 bytes to be sent through the switch, typically up to 9600 bytes per packet. With the larger packet size, there is less overhead and less latency in sending video data from one AV-over-IP device to another.

To enable Jumbo Frames on the VigorSwitch V1281, access the Command Line Interface (CLI) of the VigorSwitch. This guide details how to access the VigorSwitch CLI, with both SSH (recommended) and Telnet supported on the switch.

When connecting to the CLI of the VigorSwitch V1281, enter the username of an account with Administrative privileges, the commands referenced will not be available to accounts with User level privileges.

In the CLI of the VigorSwitch enter these commands, pressing [Enter] after each command input:

Command #	Command to enter	Purpose
1	configure	This enters configuration mode
2	jumbo-frame 9600	Sets the maximum packet size to 9600 bytes
3	end	Exits configuration mode
4	save	Saves the VigorSwitch configuration
5	exit	Exits enable mode
6	exit	Closes the CLI session

CYP HDMI-over-IP Setup for VigorSwitch V1281

The CYP HDMI-over-IP device's out of the box configuration is fully compatible with the DrayTek VigorSwitch V1281, no further configuration of each sender or receiver device is required.

If you are experiencing issues however, these settings are required in the web interface of each CYP HDMI-over-IP device:

IP Addressing

The default configuration of each CYP IP-6000TX and CYP IP-6000RX uses "Auto IP" mode, which is compatible with the VigorSwitch V1281 without further configuration required.

This is ideal because the partitioning of Source and Output ports on the VigorSwitch V1281 will block normal LAN network connectivity for devices plugged into the Source/Output ports. The Auto-IP option allows the CYP HDMI-over-IP devices to auto assign themselves an APIPA (Automatic Private IP Address) in the absence of a DHCP server to assign one. This is an address between 169.254.0.0 and 169.254.255.255, with a subnet mask of 255.255.0.0, allowing all devices that have assigned an APIPA address to communicate.

Link Pair Setup Setting

The CYP HDMI-over-IP encoder and decoders each have an option in the web interface of each unit to specify the "Pair Selection" for the Link Pair Setup - this specifies the multicast address/group used for sending and receiving video data packets. When used with the VigorSwitch V1281, these must each be set to same pair, for instance all units set to their default value of "0". The VigorSwitch V1281 would then control which Source connects with each Output.

Setting a different channel values on the CYP HDMI-over-IP devices will result in no communication between devices on different channels.

Casting Mode

The Casting Mode setting determines how the CYP HDMI-over-IP devices communicate with each other:

• Multicast mode (recommended) - The CYP IP-6000TX transmitter will send out packets using Multicast, which is sent out to all Output ports that the Source port is grouped with on the VigorSwitch V1281. This option should be left as Multicast where possible. It allows the CYP IP-6000TX to send video data in a one-to-many configuration.
• Unicast mode - The CYP IP-6000TX transmitter will send video data from itself to one other IP address (a single CYP IP-6000RX receiver). This creates a direct link between the sender and the first receiver that it detects. This means that video can only be transmitted to one screen at a time, which may be preferable for KVM (Keyboard Video Mouse) configurations.

Connecting CYP HDMI-over-IP devices to the VigorSwitch V1281

Once the VigorSwitch V1281 has Jumbo Frames configured, CYP HDMI-over-IP devices can be used with the Vigorswitch. The VigorSwitch V1281 can then be configured with its Source and Output ports, which is detailed in this guide.

The CYP IP-6000TX transmitters can then be connected into the assigned Source ports on the VigorSwitch V1281 - which are shown connected to the Red network cables in the example setup.

The CYP IP-6000RX receivers can be connected into the assigned Output ports on the VigorSwitch V1281 - which are shown connected to the Green network cables in the example setup.

The Source and Output combinations & presets of the CYP HDMI-over-IP 4K Extenders can then be selected from the VigorSwitch V1281's web interface in the [Source Selection] & [Preset Selection] menus, or via the DrayTek AVS App, which is available for free on Apple iOS & Google Android platforms through the Apple App Store & Google Play Store.
