Cause:
Informational

Solution:
SMT Smart Connected UPS with firmware 4.1 or above will communicate via Modbus over Serial and USB.
SMTL Rack Mount Smart Connected UPS models 750 and 1000 will communicate via Modbus over Serial and USB SMTL750RM2UC requires firmware 01.3 SMTL1000RM2UC requires firmware 01.5.
SMTL Rack Mount Smart Connected UPS model 1500 will communicate via Modbus over Serial only. 
SMC Smart Connected UPS do not support Modbus communication. 
SCL UPS models with an integrated Network Management Card (ie: SCL500RM1UNC, SCL500RMI1UNC) support Modbus over TCP via the Network Management Card.

SCL Smart Connected UPS models (ie: SCL500RM1UC, SCL500RMI1UC) do not support Modbus TCP.

NOTE: The SMT and SMTL Smart-UPS with a Network Management Card AP9630, AP9631, AP9635 with firmware 6.4.6 or above supports Modbus over TCP. Smart-UPS with AP9640 and AP9641 support Modbus over TCP.
