CIM 250 GSM/GPRS module<br />
Fig. 68 CIM 250 GSM/GPRS module<br />
The CIM 250 GSM/GPRS module (CIM = Communication<br />
Interface Module) enables data transmission<br />
between a GSM/GPRS network and a <strong>Grundfos</strong><br />
E-pump.<br />
The CIM 250 is fitted in the E-pump to be<br />
communicated with or in a CIU unit.<br />
The CIM 250 can communicate the following data<br />
points between the E-pump and a management<br />
system.<br />

CIM 300 BACnet module<br />
Fig. 69 CIM 300 BACnet module<br />
The CIM 300 BACnet module (CIM = Communication<br />
Interface Module), which is a BACnet master, enables<br />
data transmission between a BACnet MS/TP<br />
(Master-Slave/Token Passing) network and a <strong>Grundfos</strong><br />
E-pump.<br />
The CIM 300 is fitted in the E-pump to be<br />
communicated with or in a CIU unit.<br />
The CIM 300 can communicate the following data<br />
