ADAM 4100 Series User’s Manual
The ADAM-4100 Modbus version modules may come from the factory
set for which ADAM ASCII protocol are set as the default protocol.
If the module is connected to a Modbus network, the Modbus network
may not recognize the module. This may be caused by the incorrect
settings. ADAM-4100 module should be set-up for Modbus protocol
instead of ADAM ASCII protocol.
Please follow the steps as below for configuring an ADAM-4100 module
to Modbus protocol.
1. Configure the ADAM-4100 Module with the ADAM-4000-5000
utility (latest utility can be found at www.advantech.com
service &
support.)
2. Initialize the ADAM-4100 on a RS-485 network (the preferred
method is one module at a time on the RS-485 network).
3. With the module powered off, turn the switch in the “Init” position.
4. Power up the module
5. Wait 10 seconds for the module to initialize.
6. Using the ADAM-4000 utility, search (scan) for the module to
change the protocol. (Initial COM settings: 9600 baud, N-8-1)
7. The utility will identify the module from the search function.
8. The ADAM-4000 utility will now permit the serial data protocol to
be changed to the Modbus protocol.
9. The address and COM port settings can also be changed at this time.
10. To access the module, click on the module icon in the utility.
11. Update the settings by pressing the “Update” button.
12. Power off the module.
13. Turn the switch back to NORMAL* position.
14. The module is now ready to be placed in the Modbus network.
