BACNET INTEGRATION MANUAL FOR TB7600 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. Fig. 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 types of networ

BACNET INTEGRATION MANUAL FOR TB7600 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. TB7600 themostats' maximum data rate is 76,800 bps. If you require a maximum network length of more than 4000 feet, then repeaters are required to extend the

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: • TB7600, TB7300, and/or TB7200 thermostats are installed at both ends of the MS/TP network: 120 Ohms resistor should be installed at each end. • A TB7600, TB7300, or TB7200 d

If your BAS allows you to remove objects from your database, Honeywell recommends removing all configuration objects once your setup is complete. This will prevent unnecessary polling of unused objects and will help speed up the network. • General Options 1 Group GRP 46 and its complete list of objects; • General

Otherwise, any read or write request will occur at the Supervisory Controller’s program scan rate, which might as well be in hundredths of milliseconds. This can easily bog down a network as si
