BACNET INTEGRATION MANUAL FOR TB7200 & TB7300 SERIES THERMOSTATS
End Of Line (EOL) Resistors
MS/TP network must be properly terminated. 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, or TB7600 device is installed at one end of the MS/TP network and another device is installed at the other
end:
• Install an End-Of-Line resistor value that matches the other device's instructions regarding its EOL resistor value;
• Other devices are installed at both ends of the MS/TP network:
• Follow the other device's instructions regarding its EOL resistor value.
