LinkSprite RS-485 Shield Help

Controller: Domino
Shield: LinkSprite RS-485 Shield ([url][/url])

I’m working on RS-485 communications and have successfully been able to communicate over the Arduino IO Shield V.5 and over a USB RS-485 converter connected to the USB host port.

However, I’m not having any success using the LinkSprite RS-485 Shield. The data I receive looks like garbage and is less bytes than what I’m expecting.

Does anyone have experience with the LinkSprite RS-485 shield? Is there anything special to know about using it?

Thanks for any help.
