6.3 EUM Configuration Utility
The EUM can also be configured and monitored using the EUM Configuration Utility, a
Windows-based graphical user interface (GUI) running on a PC. The PC connects to the CCU
or EUM through the DB-9 console port, the unit Ethernet port, or from anywhere in the
LMS4000 900 MHz Radio Network. The Configuration Utility and Configuration Utility User
Guide can be downloaded from the WaveRider Web site at www.waverider.com

6.4 RSSI/Tx Quality/Antenna Pointing
The EUM Radio LED and the continuous Receive Signal Strength Indication (RSSI) reading
provide an indication of the level of the signal received from the CCU and an excellent tool for
locating and aligning the EUM antenna. Since the system is based on a polling MAC, there will
always be a signal to receive and monitor from the CCU.
The procedure for aligning the EUM antenna, which is discussed in more detail in Positioning
the Antenna on page 111, can be summarized as follows:
1. Connect the indoor antenna to the EUM and power up the EUM.
2. Once the EUM is fully booted, monitor the Radio LED while moving the antenna
around the room between suitable installation sites until you find the best signal. Use
Table 16 on page 75 as a guide.
3. 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.
4. If the best location produces a Slow Flash Radio LED, then the received signal is
marginal. To attain the best possible signal below the Fast Flash LED level, turn on
the Continuous RSSI through the command-line interface, as follows:
