SL-2-DC-002 Operating Manual
Product Overview
SL-2-DC-002 controllers remotely monitor, control and schedule devices through an independent cellular-based
management system. It has two independently controlled inputs and outputs so two devices can be managed
from one controller and operate at different voltages. The SL-2-DC-002 controller is useful in a variety of
applications including:
•Digital Advertising and Real-time Displays
•IT and Networking
•Lighting Systems
•Solar Systems
SmartLink controllers are hardwired to devices in the field and communicate through an independent Machine
to Machine cellular connection. From there, data passes through Outdoorlink’s AWS server and is available to
users in the SmartLink portal through cellular or internet access.
Every SmartLink controller can be accessed from a desktop or mobile device, enabling users to remotely react
to issues before customers are aware and resolve downtime without making a site visit.

Installation Guidelines
OutdoorLink technical support can be reached at [phone] ext. 1 or [e-mail].
Tools & Materials Needed (not provided)
•Wire crimpers
•Mini standard screwdriver to secure terminal connections
•3M two-sided adhesive tape or two-sided Velcro for mounting
Installation Tips
1. Avoid placing the SL-2-DC in fully enclosed indoor spaces unless necessary. An external antenna is
recommended when the device must be placed in an enclosed area such as a hardware cabinet.
2. When mounting external antennas, orientation and plane are important factors to consider. Verify with
Outdoorlink on the ideal mounting position per each installation.
3. Place the SL-2-DC with as much free space as possible from other electronic devices for optimal connectivity
4. Do not allow water to directly enter the controller, as it is rated for damp conditions but is not waterproof.
Installation Steps
1. Choose installation placement and confirm cable lengths are sufficient for making all device connections. The
SmartLink should be facing outward and upward for optimal cellular connectivity. Locate the SL-2-DC controller
away from direct sunlight.
2. Place the SmartLink on the chosen location and use double-sided tape or Velcro to secure the unit.
3. The SL-2-DC controller requires 18 AWG wiring for both input and output connections. For devices with barrel jack
connectors, OutdoorLink can provide a Connector Kit with female and male barrel connectors for 12V and 19V DC
devices, upon request.
4. The SL-2-DC-002 operates between 5-30Vdc input voltage at 4A per port. A supply line within this range is needed
for the input power.
5. Wiring
a. Connect the POS and NEG power supply lines to the IN1 terminal block with 18AWG wire.
b. If using an AC power supply, then a wiring harness should be supplied to connect the female and male
barrel connectors of the adapter.
c. If using a split DC supply, install one POS and NEG power supply to the IN2 POS and NEG and the
second power supply to the POS and NEG for IN2 (see Figure 4, page 5).
d. If using a single DC supply, install the POS and NEG supply to the IN1 POS and NEG, and add a jumper
wire from the IN1 POS to the IN2 POS to supply power to both outputs (see Figure 5, page 6).
6. Cellular Connection
a. Once power is connected to the controller, a green light should start flashing quickly. If the light is
flashing slowly, then the SIM card is still reconnecting to its cellular carrier.

b. The SL-2-DC includes an integrated cellular modem to enable communication between the device and
Outdoorlink’s servers and uses LTE CAT M1 cellular technology, which is designed for IoT devices. The
SL-2-DC has two antenna modes –internal and external –and is configured to internal mode when
shipped.
It is critical that the SL-2-DC is configured for the proper antenna mode. A user may change antenna
mode by pressing the “ON/OFF 2” or “ON/OFF 1” push buttons for 5 seconds. The Status LED provides
visual confirmation of what antenna mode the SL-2-DC is set to.

STATUS LED
1. Slow Blink: One blink per second continuously indicates that the device is searching for the cellular network
while in internal antenna mode.
2. Slow Blink with Two Second Pause: One blink per second for two seconds followed by two second pause
indicates that the device is searching for the cellular network while in external antenna mode.
3. Rapid Blink: Multiple blinks per second confirms the device is connected to the cellular network AND configured
for internal antenna mode.
4. Rapid Blink with One Second Pause: Rapid blink for five seconds followed by a one second pause confirms that
the device is connected to the cellular network AND configured for external antenna mode.
PORT 1 and 2 LED
1. A solid LED indicates Port 1,2 is powered with a load connected.
2. A rapid blink LED light Port 1,2 is powered without a load connected.
3. No LED indicates Port 1,2 is not powered.

7. Device Outputs
a. Connect the chosen devices to OUT 1 and OUT 2. Do this by either directly hardwiring the devices with
18AWG POS and NEG wire or use an OutdoorLink supplied wiring harness with barrel connectors.
8. Device Activation
a. Devices will not turn on unless the schedules are assigned to be ON at the time of installation in the
SmartLink portal. To do this, login to the portal: https://portal.outdoorlinkinc.com/login, search for the
last 4 digits of the ICCID number on the SmartLink controller and go to the unit’s Dashboard.
b. If the schedule is set for Always On, or the Relay is scheduled to be on at the time, the device should
power up once the controller receives power and connects to its cellular carrier. If the schedule is not
set to be on at the time, then push the Power Button located on the blue header of each Relay.
9. Confirm System Health
a. Confirm incoming voltage and each Relays load by clicking on the three vertical dots on the header of
the OutdoorLink Control Box and select “Get Unit Status.” Then check the Power Readings for battery
voltage and output loads.
SL-2-DC-002 Special Features
Variable Dimming
This feature allows a user to remotely set and schedule the intensity of lighting. A user can set the dimming percentage
along with the scheduled on –off period. This is especially important for solar applications where reduced light intensity
equates to reduced power consumption.

SL-2-DC-002 Operating Manual
Voltage Threshold Actions (VTA)
The VTA monitors the input voltage and as a function of its level invokes certain actions. There are two thresholds
provided, each with six selectable actions that can be assigned and executed once the threshold is met.
The thresholds are setup as high and low levels. This allows an action to be taken when the input voltage exceeds the
high level and an action to be taken when the input voltage is less than the low level. Combining the associated actions
allows for optimal control of batteries and overall power management.
The input voltage threshold levels are common between the two outputs. However, the output actions are independent
of one another. For example, once a threshold has been met, output 1’s action may be to remain idle and do nothing
while output 2’s action may be to open / turn off.
The six action selections for each of the voltage thresholds are outlined the table below. Only one action may be
assigned to a relay threshold at a time. VTA is configurable by users with administrative access.
VTA Settings
