If the drive does not operate according to these steps, refer to the ACH580
Hardware manual.

3. Check jumpers and switches

The settings described in this section are factory set and, for most situations, do not
require adjustment. However, it is a good practice to review these settings to confirm
that they are appropriate for the configuration installed.

Jumper and switch locations

The figure below shows the locations of the SW1 DIP switch on the E-Clipse Bypass
control board. The function and setting of this switch is explained in the following
paragraph.

DIP switch settings

The DIP switch is used to configure the serial communications termination resistors.
To reduce noise on the serial communications network, terminate the EIA-485
network using 120 ohm resistors at both ends of the network. Use the DIP switches
to connect or disconnect the on-board termination resistors. Both switches must be
positioned in the ON or OFF position to correctly configure the termination resistors.
