When viewed into the RJ11 socket, tab to the bottom, pins are ordered:
1:NC 2:GND 3:BMS_Tx 4:BMS_Rx 5:GND 6:NC
Either a direct serial interface from your hardware, a USB to serial, or a network connected TCP server device will work. Note the voltage levels are normal RS232 (and not TTL / 5V or something else).
