SRM-5A

RAD Short Haul Modem

Add to Quick Quote

RAD's SRM-5A asynchronous between Campbell Scientific dataloggers and a computer with an RS-232 serial port. The RAD modem uses unconditioned 4-wire telephone lines for transmission; data rates up to 9,600 bps are possible. The low voltage transmission levels minimize cross-talk between adjacent lines within the same cable. Data are transmitted and received at a balanced impedance, providing excellent immunity to circuit noise.

LoggerNet Datalogger Support Software, installed on an IBM-PC® or compatible computer, provides software support for data retrieval, datalogger program upload/download, and remote monitoring.
