You can connect EXT3-C-XR-T and EXT3-POE-XR-R to other HDBaseT-compatible devices that support HDBaseT 3.0 release or lower.

When EXT3-C-XR-T or EXT3-POE-XR-R are paired each to devices with a HDBaseT 3.0 release or lower, the features of the lower release device apply.

For example, you can connect:

• EXT3-C-XR-T to the Kramer TP-590R receiver.
• The Kramer TP-590T transmitter to EXT3-POE-XR-R.

For these paired sets:

• The maximum resolution that is supported is that of the highest common resolution. The TP-590R and TP-590T maximum resolution is 4K60 4:2:0 only, therefore the paired TP-590R and TP-590T define the maximum supported resolution.
• A shorter reach and USB extension are supported by each pair, therefore available per TP-590R and TP-590T capabilities.
• PoE powering and Ethernet are not supported by TP-590R and TP-590T so when paired with EXT3-C-XR-T and EXT3-POE-XR-R, respectively, are not available.

Connecting to EXT3-C-XR-T or EXT3-POE-XR-R via RS-232

You can connect via an RS-232 connection ⑭ or ③ using, for example, a PC.

EXT3-C-XR-T and EXT3-POE-XR-R feature an RS-232 3-pin terminal block connector to extend RS-232 signals via the EXT3-C-XR-T transmitter or EXT3-POE-XR-R receiver.

Connect the RS-232 terminal block on the rear panel to a device, as follows:

From the RS-232 9-pin D-sub serial port connect:

• Pin 2 to the TX pin on the RS-232 terminal block
• Pin 3 to the RX pin on the RS-232 terminal block
• Pin 5 to the G pin on the RS-232 terminal block

Setting the DIP-Switches

All changes in DIP-Switches apply immediately, on-the-fly (no need to power cycle the device), except for DIP-switches 2B and 3B which require the device to be power cycled. The DIP-switches are used to set the HDBT range, upgrade the firmware and determine IR signal pass-through.

All the DIP-switches are set to OFF (up) by default.

A - DIP-switch Settings

DIP #	Feature	DIP-1A	DIP-2A	State Description
1A, 2A	HDBT Range Mode	Off	Off	Standard range mode.
		On Off		Ultra-long range mode.Power cycle the device for the change to take effect.
		On	Off	TBD
		On	On	TBD

B - DIP-switch Settings

Changes to DIP-switches 2B and 3B only take effect after power cycling the device.

DIP #	Feature	DIP-switch Settings
1B	TBD
2B	Active USB Host	Off (default) – The device is configured as the host for connected USB devices.
		On – USB are configured as slaves to the remote connection.
3B	IR Modulation	Off (default) – IR pass-thru is enabled.
		On – IR pass-thru is disabled (add a 38KHz modulation to the IR output signal).
4B	RS-232 operation Mode	Off (default) – RS-232 FW programming is inactive (Normal operation mode is enabled).
		On – RS-232 FW programming is active.

Display Power On/Off Control

EXT3-C-XR-T communicates with the remote HDMI display that is connected to the HDBaseT receiver, via the pass-through CEC channel.

Use the DISPLAY ON button ① on the EXT3-C-XR-T to turn on or off the power of the display that is connected to the receiver. The DISPLAY ON button LED lights blue when display on the receiver side is powered on.

EXT3-C-XR-T supports CEC functionality and has been tested and verified with a large number of display models. However, Kramer cannot guarantee CEC compatibility with all CEC displays due to command variations and proprietary commands implemented by some manufacturers in some of their displays.
