below. For more details, see Section 4.
2.1 How to Install and DeviceNet Establish Communications
1. Connect your DeviceNet network cable to a 5-pin female (Phoenix-type) plug according to
DeviceNet cable wiring specifications
2. Make sure that the DeviceNet network is terminated properly.
3. The JDC Node Address (MacID) is set to 63 at the factory. Make sure no other device on
the network is set to 63, or change the JDC address to one that is not currently used (see
below).
4. The JDC baud rate is set to Autobaud operation at the factory. See below to change it to a
fixed baud rate if desired.
5. Make sure that there is power on the DeviceNet network and plug the cable into the 1782-
JDC.

After approximately 5 seconds, the Module Status LED (labeled “MS”) will go on solid
green and network LED will flash green.
7. The green Network Status LED (labeled “NS”) will go on solid after the Master recognizes
the unit on the link and allocates the connection (initiates communications).
8. The 1782-JDC is now operating on the network.

1. Set the 6-position DIP switch to the binary number representing the desired Node
Address, 0-63. (Note: Address 0 is often reserved for a Master device.)
2. Power cycle the unit by unplugging and reconnecting the DeviceNet cable.
NOTE:
T
he new address will not become effective until the unit is power cycled or a
Reset command is received from the Master.
2.3 How to Change the Baud Rate
