4.3.3 GTC116‐SettingTransmitterAddress
The GTC116 is factory set to an address of 2. Each transmitter must be assigned a unique address between 0
and 127 for BACnet or 1 and 247 for Modbus prior to connecting it to the network. Set the address in the
NETWORK submenu (Appendix A).
4.3.4 GTC116‐SettingBaudRate
The GTC116 transmitter default baud rate for MS/TP is 76,800 and for MODBUS is 19,200. Baud rate can be
configured in the NETWORK sub menu (Appendix A).
4.3.5 GTC116‐Se ttingMo dbusParity
When using Modbus communications protocol, Parity can be changed in the NETWORK submenu. Parity can

4.3.6 GTC116‐Se ttingBACnetDeviceInstanceNumber
When using BACnet communications protocol, the factory default Device Instance Number is 2. Device
Instance Number can be set as shown in the NETWORK submenu. Device Instance Number can also be
changed to any number between 0 and 4,194,302 by writing to the Device Object's Object Identifier Property
over the network.
