Introduction
Industrial automation often requires reliable communications between equipment sites separated by long distances
or harsh electrical environments. The AC40 fiber optic data link adapter satisfies the requirements of industrial
communications by using light instead of conventional electrical signals. The fiber optic data link between two
pieces of equipment is electrically isolated and completely immune to electrical noise.
The AC40 has three I/O ports; the RS-485 port, the host fiber port, and the repeater fiber port. When operating, the
AC40 passes and amplifies all signals between the host and repeater fiber port. All signals from the host fiber port
receiver are transmitted out the RS-485 port, and any signals received at the RS-485 port are transmitted out the
host fiber port.

Disassembly
The AC40 must be disassembled to access the mounting hardware, power and communications connectors. The
case is opened by turning the two captive screws on the top of the AC40 counter clockwise.

Mounting
The AC40 is normally mounted in the bottom left corner of a Mistic
panel. The bottom case half has two captive #10
screws for mounting.

Power Wiring
The AC40 has 3 different power supply options. The AC40A has a 120 VAC power requirement; the AC40B has a 240
VAC power requirement; and the AC40C has a 10 - 28 VDC power requirement. The power wires are routed to the
power connector block on the lower PC board. The power wiring should be run along the left side of the case half.
