C. Frequently Asked Questions

1. Where are the 1782-JDCx gateway User’s Manuals located?

The WRC product User’s Manuals are available from our web site Support -> Technical

Data http://wrcakron.com/data.html

2. What are the 1782-JDCx gateways and why should I consider purchasing one for my

DeviceNet network?

The 1782-JDCx gateways are communications adapter devices that provide you with a

flexible DeviceNet interface to a wide variety of ASCII devices. The JDCx models allow you

to easily and conveniently connect and integrate peripheral products with either RS-232,

RS-485 or RS-422 serial ports into a DeviceNet system, enabling you to select just the right

peripheral device for your application without limiting your selection to DeviceNet-cable

devices only.

3. How can I change the DeviceNet MAC ID of my 1782-JDCx?

The address of the 1782-JDCx will come preset from the factory for address 63. You may

change the address using the bank of 6 DIP switches on the unit: they can be set to any

address from 0 to 63 in binary (111111=address 63). The MACID or address will not

change if the switches are moved while the device is powered; power must be removed and

reapplied when a new switch setting and MAC ID are desired or a device reset command

must be issued.

4. What electrical connections are required for a 1782-JDCx gateway?

DeviceNet Cable Connection:

1, 5-pin pluggable header (male, Phoenix Contact MSTBA 2.5/5-G-5.08/AU or equivalent)

Serial Cable Connection: For RS-232 & RS-485

1, 3-pin pluggable header (male, Phoenix Contact MSTBA 2.5/3-G-5.08/AU or equivalent)

Serial Cable Connection: For RS-422

1, 5-pin pluggable header (male, Phoenix Contact MSTBA 2.5/5-G-5.08/AU or equivalent)

5. How do I begin to use a 1782-JDCx gateway?

You can begin to use a 1782-JDCx gateway by following the User’s Manual Quick Start

instructions.

6. What are the LEDs on the 1782-JDCx indicating?

There are two sets of LEDs on the unit. The two green LEDs next to the serial connector

are used as indicators for activity on the serial communication receive and transmit ports.

The other two bi-color LEDs are used to indicate the DeviceNet module (MS) and network

(NS) status. For troubleshooting or further information on status definitions corresponding to

LED actions see LED Operation in the 1782-JDCx User’s Manual.

7. On what DIN rail can I mount the 1782-JDCx?

The 1782-JDCx can be mounted on DIN rail mount EN50022 (WRC50022).

8. What are some common applications for the 1782-JDCx gateway?

A 1782-JDCx gateway provides DeviceNet communications for weigh scales, bar code

readers and scanners, display panels, robots, drives, operator stations / HMI, magnetic

code readers and other ASCII serial devices.

9. Are the 1782-JDCx gateways designed to “plug-n-play”?

Yes, the 1782-JDCx gateways are designed to “plug-n-play” using our factory default

settings: serial framing of 7N2, serial baudrate of 9600, max number of receive and transmit
