Manufacturer: Suntest Co.,Ltd
Model: IRDM-EIT
This is an Ethernet communication adapter of IRD series and all data in IRD system are transferred to the Ethernet master device.
As the protocol is Modbus/TCP, it is possible to exchange data or the parameters through VC# and VB.NET application with LAN port of Windows PC with using IRD Ethernet communication library (DLL).
Special communication board isn’t necessary.

Calculation of maximum available modules
If you would use more than one slave module, the calculation of the connection possible number is needed beforehand. The following condition gives the number of the possible module attached.
Condition 1
| Number of master module | = 1 |
| Number of slave modules | ≤ 9 |
| Occupied memory block | ≤ 64 |
Condition 2 (additional condition by the type of master module)
| Total input byte | ≤ 256 |
| Total output byte | ≤ 256 |
Occupied memory block and input /output bytes
| Module series | Memory block | Input byte | Output byte |
|---|
| IRDM-EIT | 0 | 0 | 0 |
