Step 2 - Configure Transmitter 1 for Chaining at High Bit Rate
1.
Connect Transmitter 1 to your Windows PC and start the Control Application.
2.
Click the Advanced button.
3.
The Advanced Options window opens.
4.
Select the Unit Parameters tab.
5.
Set the Unit Name to Transmitter1.
6.
Set the Chaining Input to OFF.
7.
Set the Chain No. to 0.
8.
Set the Chaining Output to ON.
9.
Click the Apply button.
10.
Select the Modulation tab.
11.
Set Modulation output to OFF.
12.
Click the Apply button.
13.
Select the Video tab.
14.
Check the Manual Checkbox next to the Video Bitrate (Mbit/s) field.
15.
Type the Bit Rate you want to use for the high bit rate transmitter (say 3.8 in my
example).
16.
Click the Apply button.
Note1: Notice in step 2.6 above, we have switched Chaining Input to OFF? In our earlier
example, this was switched ON and you may have wondered why as nothing is attached to
this transmitter’s ASI IN port.
The reason we switched it ON in the earlier example is because it has the function of halving
the bit rate of the unit automatically.
This time, we want to choose the video bit rate so we switched it off so our Manual bit rate
selections will apply. If we left it on, anything we type in manual bit rate will be overridden
by the automatic system.
Note2: For what we just discovered in Note 1, you can see that the transmitter which is
going to be configured with the higher bit rate must be transmitter one because it’s
Chaining Input is switched off and our manual bit rates will apply.
Transmitter two in this example must have its Chaining Input switched ON (so it can see
transmitter one), and this is going to automatically halve the bit rate as we discovered
earlier. However, our manual settings will be less than half the bit rate, and so will apply.
