If another BMPRO product also
needs the CAN port on the
BatteryPlus35/J35/ASPower,
both the other product and the
CommLink can be daisy-chained
by connecting to any other spare
CAN ports.
4. Connecting the BC300 and CommLink
The BMPRO BC300 External Shunt and CommLink provides additional battery monitoring for your BatteryPlus35 and J35
battery management systems, connecting directly to battery via the BC300 External Shunt. This enhances system behaviour
with temperature monitoring of the battery for greater protection.
The addition of the BC300 to the BatteryPlus35 and J35 battery management systems allows monitoring high current loads
and external charge sources.

9. CommLink LED Satus Indicator
When connecting to a parallel battery installation, the
earth strap linking the batteries must remain on the
battery terminals and must be located on the negative
battery connection side of the BC300.
When the BC300 is connected to the battery it will enter pairing
mode for two minutes, shown with a flashing blue LED. It must be
paired to the CommLink during this time.
With a pen or similar, press the CommLink pair button.
The CommLink status indicator will flash blue. It may take up to one
minute for pairing to complete.
CommLink flashes red
If the CommLink flashes red, it is not receiving data.
1. Hold down the CommLink pair button with a pen or similar
until the status indicator changes from red to orange.
This should take 5 seconds.
2. Pair the CommLink with the BC300 again.
CommLink not pairing to BC300
If the CommLink flashes orange, it has not paired to the BC300.
1. Disconnect and reconnecr the BC300’s positive flying lead from
the battery positive terminal.
2. Repeat the pairing process. If there are continued failures,
install the CommLink closer to the BC300 or identify possible
interference sources.
