2. Quick Start
To quickly install your 1782-JDC in your DeviceNet system, follow the instructions below. For
more details, see Section 4.
2.1 How to Install and Establish DeviceNet 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.
6. The 1782-JDC will undergo its initialization sequence, flashing both LED’s red and green.
After approximately 5 seconds, the Module Status LED (labeled “MS”) will flash green.
The Network Status LED (labeled “NS”) will remain off. This condition occurs while the
JDC is attempting to synchronize to the network baud rate.
7. The Module Status LED (“MS”) will go on solid after the Device successfully determines
the network baud rate. This requires devices on the network attempting to communicate
with each other. The Network Status LED (labeled “NS”) will begin to flash green. If it
turns solid red, check for a duplicate MacID on the network. If it remains off, make sure
that there are other devices trying to communicate on the network.
8. Once the Master recognizes the unit on the link and allocates the connection (initiates
communications), The Network Status LED will be solid green. The device is now being
actively scanned.
9. The 1782-JDC is now operating on the network.
2.2 How to Change the Node Address
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
The Baud Rate is set to autobaud at the factory. The baud rate can be changed through your
configuration tool in its normal manner to any baud rate except autobaud. This is due to the
fact that autobaud is not provided for in the DeviceNet specification. If you need to set the
