The EOI can be mounted remotely from the ASD as described in the section titled
. The dimensional requirements for remote mounting may also be found there. Using a screw
length that exceeds the specified dimensions may cause deformation of the outer surface of the bezel as

and should be avoided.
The interface can operate up to distances of 15 feet from the ASD via the Common Serial (TTL) Port. For
distances beyond 15 feet, the RS232/RS485 port is recommended.

Run Key Status LED — Illuminates green while stopped or red while running.
Stop Key — If pressed once while in the Local mode issues the Off command and decelerates the motor
