Section 3 — Operation and Maintenance
Serial Protocol Descriptions
Performer-HD supports several serial communications protocols. Switches
inside the Performer-HD frame must be properly set depending upon
which protocol you will be using.
The following pages provide examples of messages in the various proto-
cols and describe any operational conditions which must be met when us-
ing a production switcher protocol.
Table 3-1 provides a cross-reference
between Hexadecimal and ASCII characters.
Any protocol which allows a protect must refresh the protect within a con-
stant 30-second window or the protect will be removed. In the following
descriptions, Protocol Error, Parity, and Framing errors are mentioned.
When Protocol Error is called, the switcher displays
ERR P for half a second.
When Parity or Framing errors are received, the switcher displays ERR R for
half a second.
