4.3 TCP/IP Control
4.3.1 Control Modes
TCP/IP default settings: IP is 192.168.0.178, Gateway is 192.168.0.1, and Serial Port is
8080. IP can be changed as you need, Serial Port cannot be changed.
• Controlled by single PC: Connect a computer to the TCP/IP port of the Switcher, and
set its network segment to the same as the default IP of the Switcher (192.168.0.178).
Figure 4-2. Modify the IP of PC.
• Controlled by PC(s) in LAN
The Switcher can be connected with a router to make up a LAN with the PC(s); this
makes it able to be controlled in a LAN. The Switcher’s network segment is the same as
the router.

Chapter 4: Operation
Figure 4-3. Connect to LAN
1. Connect the TCP/IP port of the Switcher to the Ethernet port of PC with twisted pair.
2. Set the PC’s network segment to the same as the Switcher. Remember the PC’s original network segment.
3. Set the Switcher’s network segment to the same as the router.
4. Set the PC’s network segment to the original one.
5. Connect the Switcher and PC(s) to the router. In the same LAN, each PC can control
the Switcher asynchronously.
Then it can control the device via TCP/IP communication software.
