1.0 Unpacking:
Remove the EkoMiniTM repeater and the external power supply from the box. If an
EkoMini repeater kit was purchased, donor and server antennas should have been
received in separate shipping containers.
2.0 Additional Parts Needed for Installation:
Since every installation is different, other parts may need to be provided by the
installer:
•Donor antenna, unless an EkoMiniTM kit was purchased.
•Server antenna(s), unless an EkoMiniTM kit was purchased.
•50 ohm Coaxial power splitter, if more than one server antenna is
needed.
•50 ohm ½” flexible coaxial cable, plenum rated if required by building
code.
•Type N male connectors (or DIN 7-16, depending on the antenna
connector option)
•Mounting hardware for the donor antenna
•Weatherproofing compound
•Other miscellaneous installation items
3.0 Pre-setting the Configuration Switches:
The EkoMiniTM is shown in Figure 1. It has a set of eight configuration “DIP” switches
located under a small removable panel. See Figure 2. For many installations, these
switches are set properly at the factory. However, they can be verified or changed
using this procedure:
•Remove the small switch panel with a Phillips head screwdriver.
•The switches are numbered 1 through 8, as shown in Figure 2
below. They can be turned “on” or “off” using a small screwdriver or
a bent paper clip. Note that each switch is “off” when it is pushed
“up” toward the repeater mounting flange.
•Position each of the eight switches as described below.

This completes the configuration switch settings. Leave the cover off so adjustments
can be made later if needed.
4.0 Installing the EkoMiniTM:
Only qualified technicians should perform the installation. The user is cautioned that
modification or changes to this device not expressly approved by EMS Wireless
could void the user’s authority to operate this equipment.
The EkoMiniTM is designed for indoor use only. It should not be mounted outside.
•Determine the donor and server antenna(s) locations. Choose a
location for the EkoMiniTM that will minimize coaxial cable lengths to
these antennas, while maintaining adequate isolation. Also choose
a protected area such as an electrical or telephone room so the
EkoMiniTM will not be physically damaged. The location must also
be near a 100 -240 VAC, 47 –63 Hz outlet. See Figures 3 and 4
below –do not apply AC power without the coaxial cables and
antennas installed! If this is done, disconnect and then
reconnect the DC power cable after the antennas are
connected. This will initiate a software reset.

Figure 3: Do not apply power with the coaxial connectors disconnected!
Figure 4: AC power OK –coaxial cables are connected
•Four mounting holes are provided to mount the EkoMiniTM to a wall
or ceiling. Allow access clearance to the small removable panel on
the side of the repeater near the model number sticker (for access
to the configuration switches), the reset button, the telephone
connector jack (if remote alarming will be used), and both coaxial

connectors. Also, make sure you can see the front panel LED
indictors, as shown in Figure 1.
•Select a location for the external power supply, such as a protected
shelf, etc. Plug the power supply into the AC outlet, but do not plug
the power supply into the EkoMiniTM at this time. Only apply power
to the repeater after the donor and server antennas are installed
and connected.
5.0 Installing the Donor and Server antennas:
•Choose a donor antenna location that gives line-of-sight coverage
back to the donor base station, and install it according to the
manufacturer’s installation procedure.
•Install ½” flexible coaxial cable from the donor antenna to the
“Donor” port of the EkoMiniTM repeater.
•Install the server antenna per the antenna manufacturer’s
installation procedure.
•Install ½” flexible coaxial cable from the server antenna pigtail to the
“Rerad” port of the EkoMiniTM repeater.
•Most common installations will provide enough electrical isolation
between the donor and server antennas. In general, keep the donor
and server antennas separated by more than 75 feet. If there is any
question whether the isolation is adequate in a particular
installation, contact EMS Wireless Technical Support for
assistance.
6.0 Installing the Remote Alarming Telephone Cable (optional):
If the optional remote alarming is installed in the repeater, install a standard
telephone cable to the EkoMiniTM repeater using an RJ-11 connector. This should be
a dedicated telephone line. Remote alarming details are detailed in Appendix C.
7.0 Initial Power-up:
•Be sure the donor and server antennas and coax cables are
connected to the EkoMiniTM.Then, plug the power supply into the
AC outlet, and the DC power cord into the EkoMiniTM.
