CAN Hardware Termination and CAN Out PIN Configurations
Jumpers are used to configure termination for AEbus and CANbus, and the CAN Out PIN assignments.

NOTICE HAZARD OF EQUIPMENT DAMAGE
Disconnect power and all connections to LYNK II before attempting to configure header jumpers.
Failure to follow these instructions may result in damage to the equipment.

Access to Configuration Header Boards and Jumpers
To access the configuration header boards and jumpers:

1. Disconnect power and all connected cables and wires from LYNK II.
2. Loosen the keeper nut on the threaded barrel LYNK Port.
3. Unscrew the four case screws using a Phillips screwdriver.
4. Carefully separate the top from the bottom casing – Ensure the keeper nut, LYNK Port barrel, and four case screws do not become lost or drop onto exposed battery cables or terminals. Save all items to reseal the unit later.
5. Place the jumpers on the correct headers noted below to configure CAN Termination and CAN Out PINs.
6. Reinstall the LYNK Port barrel with keeper nut on the outside, mate the top and bottom casing together and replace the four screws.

Installation

Choose a clean, dry, easily accessible indoor location. All the communication ports on the LYNK II are accessible when mounted on a wall. 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.

Mounting LYNK II
Screws or bolts can be threaded through the integrated Mounting Slots (Figure 1 – 12) to affix LYNK II to a flat surface. Mounting screws, bolts and nuts are not included. Threading straps through the integrated Hold Down Points (Figure 1 – 11) can be used to secure LYNK II to an object. Secure all cables to prevent them from working loose or becoming damaged.

Installing the External Power Source
LYNK II can utilize one of three power sources. LYNK II will automatically use the highest priority source if all three power sources are connected.

Connect LYNK II to one or more of the following:

• A 13-92 VDC power supply (or battery) is connected to the Phoenix connector pin 7 (GND) and pin 9 (Vin).
• The AEbus Port or LYNK Port of a Discover lithium battery.
• A USB device (Relays will not function with USB as the only power supply)

LYNK Network Communication Cables

• HAZARD OF EQUIPMENT DAMAGE
• Do not connect a CAT5 cable from an AEbus Port or LYNK Port to a WAN or MODEM Ethernet port.
• 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 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 II Communication Gateway is internally terminated. A termination resistor is not required.

LYNK (AEbus) Network Installation and Layout for AES LiFePO4 batteries: 42-48-6650, 44-24-2800

Using a CAT5 or better cable, insert one end into the LYNK Port (RJ45) on the LYNK II. Insert the other end of the CAT5 cable into the AEbus Port located on the AES LiFePO4 battery. If there are multiple AES LiFePO4 batteries, series network (daisy-chain) them together and insert the end of the CAT5 from LYNK II into the AEbus Y-Connector at the end of the network, as shown below. The LYNK II Communication Gateway is terminated internally. Termination at the opposite end of the LYNK (AEbus) network is also required.

LYNK (AEbus) Network Installation and Layout for AES LiFePO4 batteries: 14-36-3000, 14-48-3000, 44-48-3000

Using a CAT5 or better cable, insert one end into the LYNK Port (RJ45) on the LYNK II. Insert the other end of the CAT5 cable into the AEbus Port located on the AES LiFePO4 battery. If there are multiple AES LiFePO4 batteries, network them together in a daisy chain. Connect the CAT5 cable from LYNK II to the AES Port of the battery at the end of the network, as shown in figure x. The LYNK II Communication Gateway is terminated internally. Termination at the opposite end of the LYNK (AEbus) network is also required.

LYNK Network Installation and Layout for LITHIUM PROFESSIONAL and DISCOVER HELIOS batteries:

• Mount the devices according to their installation instructions before beginning network installations.
• Attach the 950-0038 DLP T Connector to the LYNK Port on each battery (Figure 13). Ensure that the mating connectors are securely fastened.
