9. TCP/IP Controlling
The TP port of SC121D is used for TCP/IP control. Below is the introduction of TCP/IP control:
9.1 IP Configuration
1) Connect a computer to the TP port, set its IP to the same IP section as the default IP of
SC121D (192.168.0.178). As picture below:
Same IP section but cannot be
192.168.0.178
2) Enter the 192.168.0.178 to the Internet Explore, you will see the LOGIN page as below:
15
PTN Electronics Limited www.PTN-electronics.com
SC121D-TN Presentation Scaler Switcher
3) Enter the password “88888”, and then you can enter the configuration page to configure the
IP port, including the IP reset, PW reset etc. As picture below:
Notice: Serial configuration must be fixed to meet SC121D, so it cannot be changed.
After configuration, reset device, then you can use the new IP address for controlling.
16
PTN Electronics Limited www.PTN-electronics.com
SC121D-TN Presentation Scaler Switcher a) Connection and Command Control
1) Connect a computer and SC121D to the same network. Open the PTNET software (or any other TCP/IP communication software) and create a connection, enter the IP address and port of SC121D (default IP: 192.168.0.178, port:4001):
2) After connect successfully, we can enter commands to control the SC121D, as below:
Here for command entering.
All the control commands are the same as the RS232 list.
Here you will receive the feedback when a command is sent
17
PTN Electronics Limited www.PTN-electronics.com
SC121D-TN Presentation Scaler Switcher
10. Firmware Updating
The SC121D supports firmware field-updating, by USB flash disk. The Operation is:
1: Copy the file “MT23ATV.bin” to a USB flash disk. (The “MT23ATV.bin” file is provided/authorized by PTN engineering department)
2: Plug the USB flash disk to the USB port on SC121D.
3: Pressing the button “HDMI” on the front panel for 6 seconds or sending RS232 command 0698% for updating, then press the button “OK” on the remote or send RS232 command 0609% to confirm update. The SC121D will capture the new firmware from USB flash disk.
4: After updating finish, reboot and send the command “0617%” to reset to factory settings.
5: After reset, reboot again.
Notice: The name of the update file must be MT23ATV.bin.

12. Troubleshooting & Maintenance
1. When images of terminal unit output with ghost, such as the projector output with ghost, please check the projector’s setting or try another high quality connection cord.
2. When there is a color losing or no video signal output, please check the input and output end connection of VGA cable.
3. When the remote controller doesn’t works:
A. The battery has no power, please change a new one.
B. The controller was broken, please repair it.
4. When user cannot control the switcher by computer through its COM port, please check the
COM port number in the software and make sure the COM port is in good condition.
5. When switching, there are codes back but no output image, please check if there is any signal at the input end. If there is no signal input, maybe the input connection cord broken or the connectors loosen.
6. If the POWER indicator doesn’t work or no respond to any operation, please make sure the power cord connection is well.
7. If the output image is interfered, please make sure the system is grounded well.
8. If the static becomes stronger when connecting the BNC connectors, it maybe due to the incorrect grounding, please correct it otherwise it would damage the switcher.
9. If the switcher cannot be controlled by the buttons on the front panel, RS232 port or IR remote, the switcher may have broken. Please send it to the dealer for repairing.
Remarks: For any more questions or problems, please try to get help from your local distributor, or email PTN at [email protected]
