Mounting Consideration
The OEM 200 Main board and Antenna board include 0.125 inch mounting holes that can be used to install the OEM 200
into the host device with standoffs, screws, or snap-in bracket (not supplied by Allegion). It is recommended to mount PCBs
to a non-conductive dry surface using non-metallic fasteners.
Antenna board placement:
To maximize the read range performance of the OEM 200 place the Antenna Board as close as possible to the location
where the credential will be presented. We recommend using non-metallic fasteners to mount the Antenna Board to the end
product.
NOTICE
When mounting the Antenna Board we recommend keeping it at least 1 cm
away from metal planes. A metal plane within 1 cm from the antenna board
can lead to a significant drop in read range performance.
