The iRZ Collector dispatching application
– the iRZ Collector dispatching software which operates to-
gether with the iRZ Collector server application and enables remote monitoring and control of the system mo-
dems. It can be used in the dispatching center or data collection server as well as in any computer with the op-
erating system supporting the application.
External devices polling software
is used in the dispatching center to poll external devices and is provided
by their manufacturer. Generally, it operates in the client mode, and therefore the following two main methods
are used to interact with the modem: First
– the modem operates in the client mode, and a special-purpose
"layer" (for example, the iRZ Collector server application) is used to interact with it. Second
– the modem oper-
ates in the server mode that enables a third-party software to connect it directly. However in the second case
each modem requires an external

static IP address.

If your company rents an access point (APN) from a mobile network carrier, the modem will use an internal static ad-
dress.
