FC-42 - Communication Protocol
The following table defines the global parameter data:
0 - Black Screen (Default)
Input Standard
(Read Only)
(AUTO Mode Only)
Presence of Input Signal
(Read Only)
0 - Input Signal is Present
NOTE 1: These commands are sent by the unit also when Local / Global parameters are changed via the front panel or
as a result of execution of any other command.
NOTE 2: If it is necessary merely to save adjusted parameters in initial setup number (no setup number change), then
the value of byte3 must be equal to the value of byte2 - initial setup number.
NOTE 3: The reply to the Identify Machine command shows the machine name
- 1st byte: 0x7d
- 2nd byte: 0x80 + 0x00 (0 dec)
- 3rd byte: 0x80 + 0x29 (41 dec) - for the unit FC-42
- 4th byte: 0x98
NOTE 4: The reply to the Identify Firmware command shows the firmware version as
- 1st byte: 0x7d
- 2nd byte: 0x80 + the version number prior to decimal point
- 3rd byte: 0x80 + the version number following the decimal point
- 4th byte: 0x98
For example, for version 3.5, the reply would be 0x7d, 0x83, 0x85, 0x98.
