Bulkhead Connectors
The Universal Control Box contains the following military screw-type connectors:
•
J1 which is a 9-pin connector for customer power and handshake lines
•
J2 which is a 24-pin connector for sensor interface
•
J3 which is a 4-pin connector for Motor and Brake Cable from the mast
•
J4 which is an 8-pin connector for optional components such as the PC Interface,
Hand-Held Remote Control, or D-TEC. The J4 connector on the standard Universal
Control Box is RS-485, however an RS-422 optional is also available.
Printed Circuit Board
The Universal Control Box contains a printed circuit board.
The printed circuit board has three pairs of handshakes contacts as follows:
•
An enable input (For a hatch switch, vehicle stationary or other precondition contact
closure located between pins A and B on J1)
o
An open circuit will cause the Universal Control Box to display its software
version and will inhibit extension
o
A closed circuit is required between these pins to enable mast operation
•
A fully extended output (Located between pins C and I of J1)
•
A fully nested output (Located between pins G and H of J1)
The rated output of the handshake contacts is one ampere at 28 VDC. The contacts change
state when the mast is fully extended or nested. These shall be used as customer interlocks or
indicators (visual or audible). For more information on electrical installation of the Mast System,
see Section 2.6.2.7.
