Connection to control terminal
Cable processing
Before connection, prepare the cable as shown in the
drawing at right.
Note:
• Stranded wire is highly recommended.
• Wire insulation must be removed.
• Do not use solder to tin the wire.
• The recommended maximum cable length is 15 m {49
feet}.
•
Connection of F1 CNT and F2 CNT terminals
An external device is connected between CNT and COM. These terminals are isolated from the internal circuit by a
photo coupler.
•
Connection of F2 ACK and PAGE MUTE terminals
An external device is connected between each terminal and GND. These terminals operate by closing their circuits. The
GND terminal is connected to GND in this unit. A set of “dry relay” contacts are recommended to activate these features.
