ASCII-hex byte that is the (check) sum of all previous bytes (excluding
the SOP 'F' character).
E.g. The command F0400410082000001C8 has the checksum of
04+00+41+00+82+00+00+01=C8, so the complete command to send is
F0400410082000001C8.
A short-cut for debugging allows the checksum to be replaced by 2
question marks, so in the previous example you could send
F0400410082000001?? Instead. This is purely for test and debugging -
you should normally use a checksum to ensure data validity.
EOP
This is a carriage return (no line-feed) - ASCII code 13 (decimal).

Function list
These are grouped together into their associated on-screen menus.
Your unit and this manual should be used to determine the actual function of each
of the following, as only the menu text is listed here. Where an equivalent menu
item does not exist on your unit, then that feature is not supported on.
Function codes are given in hexadecimal and adjustment range is in decimal (but
always sent as hexadecimal!).
For dual-channel units the mode of operation also restricts what Window and
Output can be used the following table shows the allowed combinations:
Mode
Allowed Window and Output combinations
Switcher
Output 1 (0x00) and Window A (0x41) / Z (0x5A) / Logo a (0x61)
Independent Output 1 (0x00) and Window A (0x41) / Z (0x5A) / Logo a (0x61)
OR
Output 2 (0x01) and Window B (0x42) / Z (0x5A) / Logo b (0x62)
Dual PIP
Any combination of Output and Window
The following table is a list of all menu functions, their related function number and
