Watlow EZ-Zone PM ENET RS-485

I am having trouble talking to Watlow EZ-Zone PM controllers with labview.

I cannot get the ENET to RS-485 to show up in Max. I discovered that this is due to 64 bit windows? However I can talk to the ENET to RS-485 using VISA Resource Name: ASRL::xxx.xxx.xxx.xx::1::INSTR where xxx.xxx.xxx.xx is the IP of the ENET to RS-485.

I also tried using the Watlow driver however if I put the above resource name in for the PC Comms Port in the example included with the driver and try to initialize the port, I get the following error:

Error 1 occurred at an unidentified location

Possible reason(s):

LabVIEW:  An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.
=========================
NI-488:  Command requires GPIB Controller to be Controller-In-Charge.

I assume this is beacuse the  ASRL::xxx.xxx.xxx.xx::1::INSTR is not a valid input to the Watlow driver.

Please let me know if you have any solutions. Thanks!

System:

Windows 7 64bit

labview 2011 32bit

Max 5.5.0f0
