Water treatment plants, lift stations, and tank levels are often spread across miles. The 221930x link provides a cost-effective alternative to wired fiber or leased phone lines. It can send alarm conditions (high level, pump failure) with sub-second latency. Configuration and Operation of the 221930x Link Module
Based on the architecture of similar professional link systems, the 221930x likely boasts the following features:
Proper setup of the 221930x Link Module requires careful attention to the rotary switches and jumper settings located on the PCB. Incorrect settings are the primary cause of communication faults in these systems.
