Lochinvar cascade to Modbus changeover

I have a project where I've been hired to change 3 Lochinvar Amour boilers from cascade control to Modbus through a Tridium Jace. I've installed the Modbus cards and changed the setup in the boilers as per Lochinvar's MODB-I-O manual. Double checked addresses and baud rates. I have another Modbus device on the network that is communicating, but I can't get any response from the boilers. Even through a direct connect to a boiler my Modbus network analyzer software can't get a response.

Any help would be appreciated.

Thanks!
