• These two (2) terminals provide communication connections for dual gate applications where one
unit operates as a master and the other as slave operator.
• Shielded twisted pair must be used. The shield (drain wire) connection should be connected at
Master Unit Only to the LINK COM terminal but not both.
• Connect the DUAL LINK terminals of the two operators together.
• Connect the LINK COM terminals of the two operators together.
• Set OPTIONS DIP Switch #2 and #3 accordingly.
• If these terminals are not connected, each operator will automatically operate in single mode, if
DIP #3 is in MASTER position (OFF). If DIP #3 is set to the SLAVE position (ON) the unit is
non-functional.
• Recommended Belden Wire®, 22 AWG, type 8761, 9461, 9451, 1266A or equivalent.
1-pair shielded with drain wire. Available at your local electrical supply store.
Dual gate link connection
installing a Dual gate operator system
IMPORTANT: With a dual gate system certain control board settings and connections are required on the MASTER
unit only and some are required on both the MASTER and the SLAVE unit. The list below gives an overview.
• Gate Sequencing - DIP #2 on Master Unit
• Alarms - wired to MASTER only
• Entry Devices - can be wired to either unit
• Adjustable Auto Close - MASTER controls opening and closing for both gates)
• Locks - controlled by the MASTER unit
• Setting Limits - set DIP#3 on each operator to MASTER position (OFF) in order to set the limit for each
gate. After the limit is set, DIP #3 can be set to SLAVE (ON) position for dual mode operation.
