D77B-DSNAP is designed to be installed in the auxiliary contact locations of the
family of starters. On all starters, one or more auxiliaries can be used along with the D77BDSNAP. The following table lists starters and indicates the number of available auxiliary
locations for each.

Use the following steps and illustration in Figure 4 to mount the D77B-DSNAP:
1. Align and insert both the D77B-DSNAP feet into the auxiliary starter contact mounting
slots on the starter, as illustrated in Figure 4.
Recommendation: Use the middle auxiliary contact mounting slot on the starter contact
2. Slide the D77B-DSNAP down until a “click” is heard. This ensures that the D77B-DSNAP
is mounted securely to the starter.

Connect the D77B-DSNAP to DeviceNet
Connect the DeviceNet cable to the 5-position DeviceNet Connector located at the top of the
D77B-DSNAP.
● The 5-position DeviceNet Connector has screws for positive retention that need to be
loosened to remove the terminal block.
● The D77B-DSNAP will work with thick and thin media.
● The DeviceNet cable is color-coded and matches the colors on the DeviceNet
connector.
● Use only one wire per terminal.
● Tighten the screws to 0.5 Nm (4.5 lb-in).
For further information on DeviceNet wiring practices and power considerations, refer to the
DeviceNet Installation Planning Guide

Set the DeviceNet MAC ID and Baud Rate
The MAC ID and baud can only be set using the DIP switches on the front of the D77B-DSNAP.
A software tool (such as CH Studio) can view the settings for the D77B-DSNAP MAC ID and
baud rate, but cannot be used to modify them.
Refer to the following instructions, figure and table when setting the MAC ID and baud rate.
● Moving a DIP switch to the right is ON and moving the switch to the left is OFF. The
MAC ID is in binary with the major units numbered to the right of the switch on the side
label. Adding up the major units set to ON determines the MAC ID of the D77B-DSNAP.
Example: To set the MAC ID to 25, start from the top (or 32) and set the switches to OFF, ON,
ON, OFF, OFF, ON (16+8+1=25).
● The baud rate is set using the configuration switches B0 and B1.
Most significant bit to be at top or left end of switch block.
To set the DeviceNet MAC ID and baud rate, set the DIP switches
to the desired settings.
The following example is set to MAC ID=25 and Baud 125K.
