10-00 Page 2 2008-02-18 (1) OVERVIEW (1) The NHTC Nortec LINKS 2 Option allows for the integration of a NHTC Series humidifier within a BACnet, Johnson N2 or LonWorks network and allows those units to concurrently be monitored via the Nortec OnLine interface.
10-10 Page 1 2008-02-18 10-10 INSTALLATION.
10-10 Page 2 2008-02-18 (1) NETWORKING (1) It is possible to network up to a maximum of 8 units to a single LINKS 2. Since each unit is separately addressed, it is possible to monitor and control each unit individually. Different networking configurations may be achieved and are mostly dependant on the type of network present at the site.
10-10 Page 3 2008-02-18 (2) WIRING (A) BACNET/MSTP, JOHNSON N2, AND LONWORKS (1) The necessary internal wiring for the Gateway is already present except for the BMS network connection that can be made via twisted-pair at terminals A and B.
10-10 Page 4 2008-02-18 (3) GATEWAY CONFIGURATION (1) Protocol configuration is made at the factory, prior to final testing. Baud rates are also adjusted to the following values: Table 2. Baud Rates Protocol Default Baud Rates BACnet MS/TP 38.4 kbps BACnet / IP 10BaseT Johnson N2 9.
10-10 Page 5 2008-02-18 (5) VARIABLE DEFINITION IMPORTANT: In the variable name, “_ x ” denotes the humidifier number. If there is only one GSTC humidifier, all variable names will end in “_1”. If two units are networked together (see Figure 4), the second unit’s variable names will end in “_2”.
10-10 Page 6 2008-02-18 Table 3. Variable Definitions Variable Name R=Read W=Write Description LonWorks SNVT nvoHourOpt_x R Analogue Value Indicates the number of hours the humidifier cylinder has bee n in operation. SNVT_count_inc nvoCapLimit R Analogue Value Reads to capacity limitation applied to the unit output.
10-10 Page 7 2008-02-18 Variable Name R=Read W=Write Description LonWorks SNVT nvoFault_ x R Binary Value Indicates unit fault status. 0=no fault, 1=fault. SNVT_switch nvoHWSensor_ x R Binary Value Indicates if a high-water level condition exists in the humidifier cylinder.
