Rack mounts are commonly used by cellular, timing, and test labs utilizing GPS. The IRMS28 is
available with more options than other competitive products.
Redundancy is built into the unit with dual antenna inputs. The IRMS28 has the ability to
automatically switch antennas, allowing all connected devices to remain fully functional in the
event of an antenna failure. An external rotary switch on the front panel allows the user to
manually select the desired antenna inputs.
A GNSS receiver within the IRMS28 monitors the antenna signal strength. There is also internal
monitoring of both antennas current draw. The IRMS28 will automatically choose the healthiest
antenna. The device has been designed so that antenna selection can optionally be controlled
externally via a rotary switch overriding the internal automatic switch mechanism.
The dual power supply option allows two internal power supply units to share the load. If one unit
is not available, the other will seamlessly take over without any loss of power. The power supply
LED fault indicator is clearly visible on the front panel, and can also transmit using the contacts
made available on the back panel.
For diagnostic purposes, the IRMS28 also features a DB9 female connector interface on the back
panel.
