9: Installing the EUM
APCD-LM043-8.0 (DRAFT C) 151
4. If the best location produces a Fast Flash or ON Solid Radio LED, then the received
signal level is good to excellent, and this is a good location to install the antenna.
5. If the Radio LED is off or flashes slowly, then the antenna should be moved to a better
location. Keep in mind that the antenna and EUM do not have to be located in the
same room as the end-user’s PC since up to 100m (300ft.) of CAT5 data cable with a
ferrite bead can connect the EUM to the PC. To attain the best possible signal below
the Fast Flash LED level, turn on the Continuous RSSI through the command-line
interface, as follows:
60:ff:fe> rad rssi

6. Adjust the antenna location and pointing for maximum RSSI. You may need to adjust
the antenna and then step back each time to read the RSSI, so you do not obstruct
the signal from the CCU.
7. Once you have found a good location, you are ready to mount the antenna, as
described in
section 9.4.7, Mounting the Antenna.
9.4.7 Mounting the Antenna
The antenna bracket is designed to accommodate the RF cable and act as a strain relief.
Slow Flash ON/OFF 0.83 times per second. The signal strength is poor to
marginal.
Fast Flash ON/OFF 2.5 times per second. The signal strength is good.
Solid On The signal strength is very good.
