P-bus connections are also standard SMPTE device end pinouts. The two
connectors are identical and connected together. The P-bus port on the TDC-100B
is listen only, as of firmware version 1.1.
The data is RS-422, 38.4K baud, and the parity is selectable in the TDC-100B menu.
Parity is normally selected to be Odd. Parity selected must match the switcher, or a
‘Parity Error’ message will result, and the P-bus command will be ignored.
The P-bus protocol is the Grass Valley P-bus control standard, also supported by
Sony, Ross, and others.
