Merck Animal Health Introduces BIOMARK® IS1001 MUX Multiplexing Transceiver

The updated stationary reader platform connects up to six antennas for improved performance to evaluate fish passage and movement

RAHWAY, N.J., March 18, 2024 – Merck Animal Health, known as MSD Animal Health outside of the United States and Canada, a division of Merck & Co., Inc., Rahway, N.J., USA (NYSE:MRK), today announced the introduction of the BIOMARK® IS1001 MUX multiplexing transceiver. This updated stationary reader platform connects up to six separate antennas to deliver superior performance for the assessment of fish movement and passage in riverine environments.

            The IS1001 MUX is specifically designed for fisheries’ managers and biologists who are part of federal, state, university or tribal research programs in the U.S. and Canada. As an upgrade from its predecessor, the FS1001M, this device takes advantage of the improved performance of the IS1001 reader and the ability to decode FDX-B and HDX PIT tags. It can be used for instream or facility applications.

            “Merck Animal Health is committed to providing innovative solutions for the aquaculture industry, and our Biomark brand has specialized in building customized PIT tag detection systems for more than 30 years,” said Steve Anglea, senior project manager for BIOMARK with Merck Animal Health. “The IS1001 MUX delivers enhanced performance over earlier generations of multiplexers, and it streamlines system installations and reduces risk for our customers by centralizing electronics on the bank instead of relying on readers attached to antennas that could be lost in the river.”

            Key features of the IS1001 MUX include:

  • Multiplexes up to six separate antennas;
  • Decodes FDX-B and HDX PIT tags;
  • Ability to store more than 78,000 tag codes in the internal memory or real-time communication;
  • Compatible with BIOMARK’s remote data collection system;
  • Flexible and configurable to support a wide array of applications.
