Question 1

How to program atsc channel 20 using front panel buttons and display ?

Accepted Answer

it is very easy to change the modulated channels manually on the front panel.
1st: Use the up arrow on the front panel to go to channel 20
2nd: Press the middle button that looks like a box with lines through it to select the menu.
3rd: When you get to the option that says J83b then press up arrow and it will give you the option for ATSC. (the T on ATSC looks like an r)
4th: Press the down arrow to select the ATSC option
Note: the ATSC can be confused for ASR. They look similar but the ASR is for restoring the Petit back to factory specifications.
It is also possible to connect the PC to the modulator and set it all parameters using any browser :

All IP controlled devices like ours have their own IP address and in order to communicate with it, the PC needs to match the device subnet. for Example: our unit static default IP address is 192.168.1.10 and your PC is set to DHCP and IP address is 192.168.0.10, you would need to go and change Your computer nic address to 192.16.1.xx , the xx is between 1-254 but can not ne 10, because it would be repeating IP. This is just the nature of TCP/IP Ethernet.
The easiest way to verify your IP address is to type in windows CMD and type " ipconfig " , the command prompt will show you the computer network information and IP address.
We agree that the IP settings might not be known to all our customers, We made a special step by step document to make it easy, we will also make a video instructional video. Once the device is set to the specific channel and modulation, most likely this is the only time you need to connect it to the device.
