Performer-HD Instruction Manual

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.
