4 Home Station Hardware Setup

IP Modems

When using a CDMA or GSM digital cellular modem, Ethernet modem or satellite modem for remote communication, an Internet connection with a static IP address is required at the Home Station computer (Remote Stations can have a dynamic IP address). You may have to request a static IP (hard IP) to be allocated to the Home Station from your IT department.

Network considerations:

In some situations when using a CDMA or GSM modem, the Home Station computer may be connected to a network, which is protected by firewalls. In these instances the static IP address may be connected into a router, which splits the Internet connection between all networked computers. Under these circumstances, you may require the assistance of your IT department with the installation and network configuration aspects.

If the static IP is first connected to a router, the router must be accessed to allow for "port forwarding" at port number: 49152. This function is largely available on most makes and models of commercial routers.

In the even that your network has strict firewalls, the security software may need to be accessed to allow for STS communication permissions.

Radio

When a radio modem is used for remote communication, a second radio modem and antenna are connected to the Home Station computer through the RS-232 serial port. Solinst supplies a DB9 cable and an AC/DC Adaptor to connect a power source to the Home Station radio. The radio must have the same settings programmed as the radio used at the Remote Station (See Section 5.7). See Figure 3-4 for Home Station Radio Com Port Configuration.
