2.0 About LYNK LITE
2.1 Overview
LYNK LITE Communication Gateway unlocks the full potential of a Discover
lithium battery by enabling the internal Battery Management System (BMS)
to communicate closed-loop and in real-time State-of-Charge, voltage,
temperature and status to compatible devices, such as solar or mobile
inverter-chargers, on and off-board industrial chargers, displays, load centers,
motor controls, PLCs and telematics. CANopen Interface and Discover
Generic Serial CAN Guides are also available for developers.
2.2 Compatible Batteries and Devices
A battery or device must have a compatible port such as a LYNK Port to
communicate with a LYNK LITE device.
LYNK Port
• LITHIUM PROFESSIONAL batteries: DLP-GC2-12V, DLP-GC2-24V, DLP-
GC2-36V, DLP-GC2-48V, DLP-GC12-12V, DLP-GC12-24V
2.3 Compatible Communication Protocols
LYNK ACCESS software for 64-bit Windows 10 is required to congure LYNK
LITE devices for communication with compatible external devices such as
inverters, chargers and motor controllers. Download the current version
of LYNK ACCESS software from the Discover Battery website to obtain the
most up-to-date suite of available device congurations. Interface guides for
CAN open and Discover Generic Serial CAN are available from the Discover
Battery website.
2.4 Firmware Revision
This User Manual is valid for LYNK rmware version 1.4.0 and above. Use
LYNK ACCESS software to view the rmware version of your LYNK LITE
device.

4.5 Power Sources for LYNK LITE
LYNK LITE can utilize two power sources. Both power sources can be used
alone or simultaneously. LYNK LITE will automatically use the highest priority
source.
Priority Source
1LYNK Port of enabled batteries
2USB device
NOTE
LITHIUM PROFESSIONAL batteries must be set to ON to supply power and
communicate data with LYNK LITE devices.
LITHIUM PROFESSIONAL Batteries
LITHIUM PROFESSIONAL batteries will supply power to LYNK LITE using the
network cable connected to the LYNK Port.
5.0 Installation
Choose a clean, dry, easily accessible indoor location. All the communication
ports on the LYNK LITE are accessible when mounted. Clearance of at least
100 mm (4 inches) from the connection points on the device is needed to
allow for the bend radius of connected cables.
5.1 Mounting LYNK LITE
Screws or bolts can be threaded through the integrated Mounting Slots to
afx LYNK LITE to a at surface. Mounting screws, bolts and nuts are not
included.Threading straps through the integrated Hold Down Points can be
used to secure LYNK LITE to an object. Secure all cables to prevent them from
working loose or becoming damaged.
5.2 Installing the External Power Source
LYNK LITE can utilize two power sources. Both power sources can be used
alone or simultaneously. LYNK will automatically use the highest priority
source.

Connect LYNK LITE to one or more of the following:
• The LYNK Port of a Discover LITHIUM PROFESSIONAL battery.
• A USB device
5.3 LYNK Network Communication Cables
CAUTION
HAZARD OF EQUIPMENT DAMAGE
• Turn OFF all devices before connecting cables.
• Mixing the LYNK Network with other networks may result in
equipment malfunction and damage.
Failure to follow these instructions can damage equipment.
Networking Guidelines:
• Separate data and power cables and allow for separation between data
and power cables. Avoid interference and data corruption caused by
running network cables bundled with power cables.
• Allow for LYNK Network cable slack. Ensure that LYNK Network cables
are slack and not in tension.
• Isolate the LYNK Network. Do not mix other networks with the LYNK
Network.
NOTE
The LYNK LITE Communication Gateway is internally terminated. A termination
resistor is not required.
LYNK Network Installation and Layout for LITHIUM PROFESSIONAL batteries:
1. Mount the devices according to their installation instructions before
beginning network installations.
2. Attach the 950-0038 DLP T Connector to the LYNK Port on each battery
(Figure 5). Ensure that the mating connectors are securely fastened.
3. Insert the male end of the cable into the female end of the
950-0038 DLP T Connector and vice versa.
4. Repeat until all batteries have been attached in a series network (Figure 6).
5. Attach one end of the series network to the LYNK Port on LYNK LITE.
Termination of the other end is not required.
