SRM-5A

Short Haul Modem

The SRM-5A is an asynchronous modem used for local communication between a datalogger and a computer. Two SRM-5A Short Haul Modems are required; one at the "datalogger end" and one at the "computer end." Each short haul modem transmits over an unconditioned 4-wire telephone line and operate at data rates up to 9,600 bps.

SRM-5A Benefits

  • Provides the easiest link for communicating with one datalogger over longer distances
  • Low voltage transmission levels minimize crosstalk between adjacent lines within the same cable.
  • Data are transmitted and received at a balanced impedance, providing excellent immunity to circuit noise.
  • Transmits up to 6.2 miles using 19 gauge cable at 9600 bps
  • Transmits up to 7.6 miles at 1200 bps
