CAUTION
EMB-S2 controllers must be installed in accordance
with national, state, and local electrical codes and
requirements
DESIGN CONSIDERATIONS
Below are some recommendations for successful
dimming using the EMB-S2. The dimming control wires
are referenced as Dim+ and Dim-. The dimming
signals have a Maximum voltage of 10V DC.
•Use multi-strand 18 Gauge Wire for noise
immunity and current capability
•Do not ground the dimming wire; this is a
return signal and is critical for dimming
•Route dimming wires away from AC lines if
possible
•Use connections with properly sized
connectors
•Eliminate excess wire between fixtures; Line
length will cause voltage drop
•Maximum of 4 LED Drivers per controller,
consult Synapse Support if a greater ratio is
needed.

INSTALLATION INSTRUCTIONS
WARNING: TO AVOID FIRE, SHOCK, OR DEATH:
TURN OFF POWER AT CIRCUIT BREAKER OR FUSE
AND VERIFY THAT POWER IS OFF BEFORE WIRING!
MOUNTING
Secure with 1 #4 screw (max diameter of .312
inches) and standoff.
1. Mounting Options: Mount in an LED Fixture or a
Troffer. For the EMB-S2, an external antenna
utilizing a u.FL connector must be used to provide
RF connectivity to the SNAP mesh network.
2. Place the EMB-S2 in desired location and secure it
using #4 sized screw and stand-off using the
mounting hole located in the center of the board.
Prior to permanently mounting the EMB-S2, make
sure the antenna is free of any objects within 3 in.
of the internal or external antenna.
Note: When installing the EMB-S2 into an enclosure,
consideration of the internal or external antenna
position and interference is required in order to provide
the most optimum wireless signal strength.
•When installing the EMB-S2 into an enclosure,
consideration of the external antenna position and
interference is required in order to provide the
most optimum wireless signal strength. Prior to
permanently mounting it, make sure the antenna
points directly upward or downward and is free of
any metal objects within 12 in. of the antenna
(Figure 1).

WARNING AND CAUTIONS:
•TO AVOID FIRE, SHOCK, OR DEATH; TURN OFF POWER AT CIRCUIT BREAKER
OR FUSE AND TEST THAT POWER IS OFF BEFORE INSTALLING!
•PROPER GROUNDING REQUIRED TO AVOID STATIC DISCHARGE WHICH
CAN DAMAGE CONTROLLERS DURING INSTALLATION.

INSTALLATION GUIDE

21-EMBS2-INS A-1
INSTALLING THE ANTENNA
To install the antenna:
3. Make sure the power is off.
4. Attach the u.FL cable (Figure 5) to the u.FL
terminal (Figure 4).
5. Use the insertion tool, PN U.FL-LP-IN, to mate the
connectors. The mating axis of both connectors
must be aligned so that the connectors can be
mated. The “click” will confirm a fully mated
connection. Do not attempt to insert on an
extreme angle.
6. Route the antenna cable such that there is no
upward tension between the cable and the u.FL
connector.
7. To disconnect the connectors, insert the end
portion of the Extraction Tool, U.FL-LP-N-2, under
the connector flanges and pull off vertically, in the
direction of the connector mating axis.
Figure 4- u.FL Terminal
CONNECTING THE u.FL CABLE
An u.FL antenna may be connected to the EMB-S2 in
order to get maximum RF connectivity. The
recommended antenna kits are:
•KIT-ANTUFL18-01
18” u.FL cable with right angle antenna
•KIT-ANTUFL18-02
18” u.FL cable with straight antenna
•KIT-ANTUFL18-03
18” u.FL cable with right angle stubby antenna
•KIT-ANTUFL18-04
18” u.FL cable with straight stubby antenna
Please see the EMB-S2 cut sheet or contact Synapse
sales for more information.
ATTACHING THE ANTENNA
8. Make sure the power is off. When handling the
antenna cable, the technician must be grounded
with a proper ground strap.
9. Remove red rubber dust cover, the washer, and
nut from the antenna connector.
10. Determine best location for external antenna
position and create an opening to mount the
antenna and bulkhead (See Figure 6 for
measurements).
11. Feed the bulkhead through the opening in the
fixture. (Note: Recommended max thickness of
fixture wall is 6mm or 0.25 inches. This allows
enough threads on the outside of the fixture for a
good antenna connection.)
12. Place the washer and the nut back on the antenna
connector and secure to fixture.
13. Screw on the antenna hand tight. Tighten a 1/4
turn with a pair of needle nose pliers. Do not over
tighten or the RF pin in the bulkhead will crack,
creating poor RF link quality.

CONNECTING SENSORS
Note: Steps 14-18 are for adding sensors to the
EMB-S2 controller; if you are not connecting
sensors skip this section.
There are two sensor inputs on the EMB-S2 designed
for low powered (24v DC) type sensors.
•The Input A is used to connect sensor A.
•The Input B is used to connect sensor B.
14. Connect the sensor power wire to the AUX out on
the LED driver (the LED driver powers the sensor).
15. Connect the sensor common to the
COMMON/DALI- or COMMON/DIM- based on the
LED driver you have.
16. Connect the sensor CTRL/Control wire to the Input
A+ or Input B+ of the EMB-S2 controller.
17. If you are using more than one sensor then
duplicate the installation as described above.
18. Sensors must be configured in software before
they are functional in a SimplySnap system.
(See Figures 2 and 3)
WIRING THE EMB-S2 CONTROLLER
Note: Unless specified, the connections to a
standard Dim to Off LED driver and the DALI 2
LED driver are the same.
19. Connect the 12-24VDC Aux output from LED driver
to the EMB-S2.
20. Connect the Aux ground from the LED driver to the
EMB-S2.

CONNECTING THE DIMMING CIRCUIT
Note: Steps 21-22 are for connecting up to a
Standard Dim to Off LED driver; if you are using a
DALI 2 LED driver skip to steps 23-24.
21. Connect the DIM- wire on the LED driver to the
DIM- output on the EMB-S2.
22. Connect the DIM+ wire on the LED driver to the
DIM+ output on the EMB-S2. (See Figure 2)
Note: Steps 23-24 are for connecting up to a
DALI 2 LED driver.
23. Connect the DALI- from the EMB-S2 to the DALI-
/COMMON wire on the LED driver.
24. Connect the DALI+ from the EMB-S2 to the LED
driver DALI+. (See Figure 3)
POWERING UP THE FIXTURE AND
CONTROLLER
After connecting the Controller to the LED Driver and
any sensors, make sure to cap any unused wires.
Switch power on to the fixture. The light should turn
on.
Note: When switched on, lamps should turn on to
full brightness with approximately 10 VDC signal
on the DIM+ wire using the DIM- wire as
reference.
STATUS LED
Note: When the controller is powered the
following colors indicate the current status.
•Red = No Network Found (Communication Lost)
•Blinking Green = Network Found, Controller Not
Configured (Device not yet added to SimplySnap)
•Green = Network Found, Controller Configured
(Normal Operation)
NOTE: Refer to the SimplySnap User’s Manual for
information on provisioning the EMB-S2.

WARNING:
· If a single Synapse controller is used to drive the DIM+
input of multiple LED drivers, then all of the DIM- lines
from all drivers MUST be directly tied/shorted together to
provide a common return/ground to the controller.
· Synapse will not warranty or be liable for designs with
any other electronic means of coupling DIM- lines from
multiple drivers.
