Hi Denis,

Modbus is not natively supported on a SURTD model UPS. You would need to purchase a smart-slot accessory, the AP9630/31/35 network management card. The AP9630/31 have support for Modbus TCP (as of firmware rev v6.4), and the AP9635 supports Modbus TCP and RTU (also as of firmware rev v6.4).

Here's the register map for the SURTD: http://www.apc.com/salestools/LFLG-A32FWS/LFLG-A32FWS_R1_EN.pdf
