AVG-TMX88PRO

The IR signal is sent by corresponding IR remote, then it is transferred to the
HDBaseT receiver, then to the corresponding zone of the matrix through the cat
cable, finally it is transferred to the IR OUT port and received by the controlled
device.

Switching Operation: (8 IR IN ports correspond with 8 HDMI input ports separately
in default mode.)

Sending command (see RS232 Control section 5.3): [x1]R[x2].

x1: Corresponding to the 8 IR OUT ports of the matrix, the IR transmitter

connected to this port can be placed at IR receiving area of output device or
the AVG-TMX88PRO itself.

x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with IR

IN port connects with IR receiver) number of AVG-TMX88PRO.

Example: Send command “3R2.” to transfer IR signal received from zone 2 to IR

OUT port 3.

5.4 TCP/IP Control

The AVG-TMX88PRO features a TCP/IP port for IP control.
Default settings: IP: 192.168.0.178; Subnet Mast: 255.255.255.0; Gateway:

192.168.0.1; Port: 4001.
IP & gateway settings can be changed as needed, the Port cannot be changed.
Connect the Ethernet port of the control device and TCP/IP port of the AVG-

TMX88PRO and set the IP address in the same range of IP address of the matrix,
users are then able to control the device via the web-based GUI or TCP/IP
communication software.

5.4.1 Control Modes

The AVG-TMX88PRO can be controlled by a PC without Ethernet access or PC(s)
within a LAN.

 Controlled by PC
Connect a computer to the TCP/IP port of the AVG-TMX88PRO and set its network

address in the same address range as the default IP address of the matrix (Default:

192.168.0.178).

 Controlled by PC(s) in LAN
Connect the AVG-TMX88PRO, a router and several PCs to setup a LAN (as shown

in the following figure). Set the network subnet of AVG-TMX88PRO to the same as
the router’s, then PCs within the LAN are able to control the AVG-TMX88PRO.

Same network
subnet as the
switcher

AVG-TMX88PRO

Follow these steps to connect the devices:

Step1. Connect the TCP/IP port of AVG-TMX88PRO to Ethernet port of PC with a

cat cable.

Step2. Set the PC’s IP address in the same range as the matrix’s default IP. Log

into the matrix via its GUI.

Step3. Go to the network settings and set the AVG-TMX88PRO’s IP address in the

same range as the router.

Step4. Set the PC’s IP back to DHCP.
Step5. Connect the AVG-TMX88PRO and PC(s) to the router. PC(s) within the LAN

are then able to control the 4K HDBaseT 8x8 Matrix Switcher.

Control is now able via device GUI.
