Identifying registers on a Mitsubishi Modbus Gateway

I am designing a building management system that uses a Honeywell Hawk integration controller. I am trying to integrate a Mitsubishi air conditioning system into the controls; for this l have to use a device to convert from the close M-Net system to the open Modbus protocol so l can read and write to the registers as required.

Has anyone ever used one of these MOD-IP/50 units before, the information provided by Mitsubishi is not very help full at all; l have been told that the M-Net addresses will be the same as the Modbus device addresses, however this does not seem to be the case in practice, l need to read and write information to 40 devices addressed on the M-Net 1-40 if anyone has experience with this device l would be grateful for any help.
