Global Water 800-876-1172 • globalw.com I. Client Server Radio Network Basics A radio network for Global Water data loggers has one or more loggers in the field connected to client radio modems, and a single server radio modem connected to a PC running the Global Access software. In the following diagram, when the PC is running Global Access, it controls the Server Radio which establishes communication with all client radios in range.
Global Water 800-876-1172 • globalw.com higher. Older versions of Global Logger II do not support a “Fixed Baud Rate” mode which is required for radio communication.
