Dyness BX51100 & Mecer SOL-I-AX-8M2

Good Morning / Evening,

I recently installed the inverter/battery setup Dyness BX51100 & Mecer SOL-I-AX-8M2, this is my first time experiencing Lithium Batteries with BMS and Com Ports, The inverter keeps complaining about a communication issue, to be more specific Error 61, I made a custom RJ45 Cable that does the crossover between the Inverter and Batttery per Manuals. I have set the DIP switch to 0100 as per the manual of the battery, but still getting a communication error with Inverter Battery Type on LIB, If anyone can help that would be great, I have contacted both Mecer ZA and Dyness ZA with no answer. Please see attached Battery Manual and Linked Inverter Manual.
