AERCO XPC GATEWAY Communications - Manual (Page 75)

GF-122 AERCO XPC GATEWAY
75
• Because any two pieces of building automation equipment can vary with application, so can their
communications protocol
• To facilitate the communications between the various applications in a robust and efficient manner,
protocols are designed with those specific applications in mind
7.3 WHY BUILD INTHE MOST WIDELY USED PROTOCOLS?
• Manufacturers can now provide a translator with their units that can be seamlessly integrated into a
BAS
• For the building owner, it means upgrade and expansion costs will be competitive
• Expensive Gateways are eliminated
• Field selection of the protocol requires less up-front coordination, thus reducing manufacturing costs
• Flexibility and simple configuration allows the customer to make future additions and changes
without additional costs
• More opportunities for sales
7.4 WHAT DOES THE SITE INTEGRATOR NEED?
The building owner must supply the following information to the site integrator:
• Protocol Conformance Statement (Refer to SECTION 16)
• Unit-specific object listing (for LonWorks, an XIF file may be required.) See Application Note for file
generation
The site integrator then supplies the building owner with the:
• Device address
• Network baud rate
• Network numbers (BACnet only)
The specific site settings are then applied to the translator using this information. Each protocol setting
has a unique configuration. Refer to the section on Configuring Protocols.
