Control Panel Reference
TEN–20/20–TEN Panels and Serial Interface
TEN–20, 20–TEN remote control panels and the Serial Interface
may be used to control Performer. These panels are:
■
10BPS, 20BPS Button-Per Source control panels. 1
rack-unit (1.75 inches) tall. Standard
19-inch rack-mount panel. Audio-
follow-video only.
■
MBCP Multibus control panel. 1 rack-unit
(1.75 inches) tall. Standard 19-inch
rack-mount panels. Allows control of
up to four Performers. Audio-follow-

■
SERIM Serial Interface. 1 rack-unit (1.75
inches) tall. Standard 19-inch rack-
mount. Allows serial control of
Performer from an external computer
when other serial control panels are on
the RS-485 bus as well.
Panel Protocol Selection
In order to use these panels with Performer, you must set the
Performer for one of the TEN–20, 20–TEN protocols. The four
protocols are described here. Instructions for setting the protocols
begin on page 2 - 9 and in the Switch Reference table on page 2 -
41.
When a TEN–20 protocol is selected, the Performer serial port is
forced to 76.8k baud, 8 data bits, no parity, regardless of Performer
baud and parity determining switches. In addition, the function of
Performer‘s address selection switch (S1) changes to become a
source, destination, and level offset-determining switch to permit
multiple Performers to be used on the same bus in different ways.
Instructions for setting S1 are included here. Four TEN–20
protocols are available. They are described in Table 2-8.
