Serial Protocol Descriptions
Performer supports several serial communications protocols.
Switches inside the Performer frame must be properly set
depending upon which protocol you will be using. Refer to the
Common Configuration portion of the Installation section for switch
setting instructions.
The following pages provide examples of messages in the various
protocols and describe any operational conditions which must be
met when using a production switcher protocol. Descriptions for
the following protocol are presented in the order shown:
■ Performer ASCII
■ Performer Remote Control, TEN–20/20–TEN
■ TEN–20/20–TEN Serial Interface
■ TEN–XL ASCII
■ TEN–XL SMPTE
■ Model 100 and 110 Production Switcher
■ Model 200 Production Switcher
■ Model 300 Production Switcher
■ SMPTE 3245-E
Table 3-1 provides a cross-reference between Hexidecimal and
ASCII characters.
Any protocol which allows a protect must refresh the protect
within a constant 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 about half a second. When Parity or
Framing errors are received, the switcher displays ERR R for
about half a second.
