Installing The Unit - Equinox Systems ESP-2 MI Installation Manual

This termination is typically used in RS-485 environments when the device is the fi rst or
last on a multi-drop line for a 2-wire confi guration. This termination should always be set
when the unit is set for RS-422, as this is point-to-point confi guration.
If your confi guration includes supplying your own external termination, the termination on
the ESP-2 MI should not be used.
To disable termination, remove the jumper entirely.
6. When the RS-485HD interface is enabled in hardware, you will be able to select the
transmitter/receiver mode during startup. For more information on these software-
confi gurable options, see Interfaces.
7. Replace the cover on the unit and reinstall the four screws.

Installing the Unit

The ESP-2 MI can be installed on a table, on a DIN rail or on a wall.
WARNING: The power outlet should be installed near the equipment and should be
easily accessible.
The ESP-2 MI supports hot swapping, that is, you may replace an existing ESP-2 MI with a
similarly configured unit without affecting the server or having to reconfigure the ports.
