Offgridtec BMS-LINK for IC-Series
 Thanks for selecting the BMS protocol converter. Please read this
manual carefully before using the product.
 Please keep this manual for future reference.
BMS Protocol Converter
1 Overview
BMS-LINK is an external BMS protocol converter with an independent MCU.
Setting the "PRO" parameter through the remote meter or PC software after
connecting the BMS-LINK to IC* and lithium battery. Different
manufacturers' protocols can be converted into our standard protocol, which
improves the actual application's flexibility. Compared with the traditional
built-in BMS protocol conversion module, this converter has stronger
application flexibility and expansibility. It is more suitable for our all-in-one
products and other products to communicate with the lithium battery BMS.
*Except the IC-12
Features:
 Independent MCU
 Dual RS485 com. port
 Support multi BMS protocols conversion
 Freely setting the protocol number
 Reliable protocol conversion and communication
 Optional remote meter or PC software to set the protocol number
 Simple installation and friendly operation
 The port connected to the lithium battery is an isolated RS485 communication
port, and the port connected to the all-in-one products is a non-isolated RS485
communication port.

Step3: Modify the "PRO" parameter into the BMS protocol number through
the remote meter or PC software(Take the remote meter as an example):
① In the real-time interface, press the UP+DOWN button and hold on for
2s to enter the engineer's operation interface.
② Press the UP/DOWN button to select the "PRO" parameter(item 40).
③ Press the SET/ENTER button and hold on 2s to enter the parameter
modifying interface.
④ Press the UP/DOWN button to modify the "PRO" parameter.
⑤ Press the SET/ENTER button to confirm the modification.
⑥ Press the ESC button to exit.
⑦ Restart the all-in-one product to make sure the BMS protocol number is
modified successfully.
1) Please refer to the "BMS Lithium Battery Protocols & Fixed ID Table" or
contact our technical support department for the supported BMS
manufacturers and protocols.
2) Please make sure the lithium battery's default ID has been modified into
the fixed ID before setting.
