Installation Reference
OPTION Connector Cabling
The OPTION connector slot may be used in two ways:
■ With Tally Board option, which allows Joystick Override/
Custom Control and Tally Relay connection
■ With Looping option, which parallels and duplicates the
pinouts of the REMOTE connector.
Tally Board Option
When used to connect Joystick Override or a custom control
panel, an optional Tally Relay Board and cable/connector
assembly must be installed in Performer. This installation is
described next in this section. Once the Tally Relay Board and
connector are installed, you can cable control and tally as
illustrated below and listed in Table 2-5. (See the
Operation
section of this guide for Joystick Override and control operating
information.)
Relay closures follow video source selections. When the
corresponding video source is selected, the relay closes and
remains closed until the video source is released.
CAUTION
Relays provide DRY CONTACT CLOSURE only. NO
VOLTAGE or PATH TO GROUND is provided. Relays are
rated at 42.4 volts, (30- volts RMS), 1 Amp,ere resistive or
inductive. UL Safety Extra Low Voltage requirements must be
met
