SECTION 19 CONFORMANCE STATEMENT FOR JOHNSON N2
IMPLEMENTATION
Date: 11/22/05
Vendor Name:
OEM
Product Names: Extended Protocol Converter
Product Model Number: XPC
Applications Software Version:
HW_Exec_B
Firmware Revision:
2.03
Product Description:
The XPC is a general purpose building automation translator with custom programmable functionality,
designed for communicating through multiple protocols. N2 network points are spawned within the device
as a result of downloading graphical control programs. The XPC translator speaks the Johnson Controls
N2 Open Protocol as described in the Metasys N2 System Protocol Specification (for Vendors)
document, revision 6/13/96, and acts as an N2 Master or Slave. Further details on the N2 supported
implementation are described below.
