BACNET INTEGRATION MANUAL FOR TB7200 & TB7300 SERIES THERMOSTATS Cable Type Honeywell recommends the use of balanced 22-24 AWG twisted pair with a characteristic impedance of 100-130 ohms, capacitance of 30 pF/ft or lower. A braided shield is also recommended. Impedance A value based on the inherent conductance, resistance, capacitance and inductance that represent the impedance of an infinitely long cable. The nominal impedance of the cable should be between 100 Ωand 120 Ω. However using120

BACNET INTEGRATION MANUAL FOR TB7200 & TB7300 SERIES THERMOSTATS NETWORK CONFIGURATION EIA-485 networks use a daisy chain configuration. A daisy chain means that there is only one main cable and every network device is connected directly along its path. Figure 1 illustrates two improper network configurations and the proper daisy chain configuration. Other methods of wiring an EIA-485 network may give unreliable and unpredictable results. There are no troubleshooting methods for these type

BACNET INTEGRATION MANUAL FOR TB7200 & TB7300 SERIES THERMOSTATS Maximum Cable Length The maximum length of a chain is related to its transmission speed. The longer the chain, the slower the speed. Using proper cable, the maximum length of an EIA-485 daisy chain is 4000-ft (1200 m). This will only work reliably for data rates up to 100,000 bps. The maximum data rate is 76,800 bps for TB7200 and TB7300 Series thermostats. If you require a maximum network length of more than 4000 feet, then re

For daisy chain configurations, you must install an EOL resistor at each end of the daisy chain. Depending on your MS/TP network configuration, the resistance value of the EOL resistor may change: • TB7200, TB7300, or TB7600 Series devices are installed at both ends of the MS/TP network: • 120 Ohms resistor should be installed at each end. • A TB7200, TB7300, o

BACNET INTEGRATION MANUAL FOR TB7200 & TB7300 SERIES THERMOSTATS NETWORK ADAPTER The polarity of the connection to the cable is important. From one module to the other it is important that the same colored wire be connected to “plus” or “+” and the other colored wire be connected to the “minus” or ”-“. Figure 5 shows the proper MS/TP connections and the location of the Status LED. This Status LED may help to troubleshoot network problems. Fig. 5. Correct MS/TP connections and location of a St

If the 3 party device does not support COV, the graphic interface then relies on a pre-configured polling interval, which is usually in hundredths of milliseconds. Any device containing a monitored object could be subject to network traffic congestion if such a polling interval is used. Honeywell strongly
