The fuse monitors in Lynx Distributor modules with older firmware (before serial number HQ1909) cannot
detect a blown fuse when batteries are connected. It can only detect a blown fuse if loads are connected.
3.3. The RJ10 cable
The RJ10 cable provides power to the Lynx Distributor originating from a Lynx Smart BMS or Lynx Shunt VE.Can and transfers
data between the Lynx Distributor and the Lynx Smart BMS.
The Lynx Distributor does not have an in-build power supply to supply its fuse detection circuit, it relies on this power to be
supplied from a Lynx Shunt VE.Can or a Lynx Smart BMS via the RJ10 cable. If the Lynx Distributor is used without a Lynx Shunt
VE.Can or a Lynx Smart BMS, it needs to be powered in an alternative way, so that the fuse detection circuit is operational.
To power the RJ10 cable for standalone use do the following:
• Connect pin 1 of the RJ10 connector to 5V (4.5V-5.5V).
• Connect pin 4 to GND.
The RJ10 connection is not protected against reverse polarity. A wrong RJ10 connection can irreversibly
damage the Lynx Distributor’s electronic circuits.

The Lynx Distributor communicates operational status and the status of each fuse via the RJ10 cable to a Lynx Smart BMS. The
data can then be accessed via the VictronConnect App, GX device and to the VRM portal.
The communication feature has been implemented in the Lynx Distributor from serial number HQ1909 or
above.
Communication is not possible in combination with the Lynx Shunt VE.Can.
