Some users of the LI-7000 CO₂/H₂O Analyzer use modems to transfer data over large distances (e.g. the Short Range Modem SRM-3A, which can transfer signals up to a distance of approximately 2.5 miles). When using modems of this type with the LI-7000, data does not travel through the modem to the computer. This is due to two different conditions that are occurring simultaneously.
