2 Quick Start
To quickly and easily install your JDM in your DeviceNet system, follow the instructions below. For
more details, see Section 2.3.
To Install and Establish DeviceNet Communications
1. Connect the DeviceNet cable to the 5-pin plug (supplied) according to DeviceNet cable wiring
specifications.
2. Make sure that the DeviceNet network is terminated properly. (See Section 3.5 below.)
3. The JDM 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 JDM address to one that is not currently used (see below).
4. Use the autobaud feature of the JDM.
5. Make sure that there is power on the DeviceNet network and that it is plugged into a Master device.
6. Plug the DeviceNet cable into the JDM.
7. The JDM will undergo its initialization sequence, flashing both LEDs. After approximately 4 seconds,
the Module Status LED (labeled “MS”) will go on solid green and network LED will flash green.
8. The green Network Status LED (labeled “NS”) will go on solid once the Master recognizes the unit on
the link and allocates the connection.
9. The JDM is now operating on the network.
2.1 How to Change the Node Address
1. The address is set using the 6-position DIP switch block. They define the address as follows:

command (to the class 1 Identity object) or a power cycle.
