ADAM 4000 Series User’s Manual
The ADAM-4000 Modbus version m odules may come fro m the
factory set for which ADAM ASCII protocol are set as the default
protocol.
If the m odule is connected to a Mo dbus network, the Mod bus
network may not recognize the module. This may be caused b y
the incorrect settings. ADAM-4000 m odule should be set-up f or
Modbus protocol instead of ADAM ASCII protocol.
Please follow the steps as below for configuring an ADAM-4000
module to Modbus protocol.
1. Configure the ADAM-40 00 Mo dule with the ADAM-400 0 u tility
(latest AD AM-4000 u tility can be found at www.advantech.com
service & support.)
2. Initialize th e ADAM-4000 on a RS -485 n etwork (t he 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.
(For some older Adam models, use a n external wire to c onnect the
INIT* terminal to the GND terminal)
4. Power up the module
5. Wait 10 seconds for the module to initialize.
6. Using th e ADAM-4000 u tility, search (scan) for th e mo dule 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 d ata 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. (For th e older Adam
models, remove the wire between the INIT* and GND terminals)
14. The module is now ready to be placed in the Modbus network.
