Page 5: Introduction
The CEG uses BACnet MS/TP open protocol to monitor chiller operation. The gateway can communicate either through hardwired RS-485 or wirelessly, using mesh network technology with self-healing capabilities. The CEG then aggregates, packages, and transmits the data to the Johnson CEG and TMR Technical Bulletin Johnson Controls... - Page 6 CEP web UI. The CEG follows the same guidance for MS/TP rules as other Johnson Controls devices, including a limitation of number of devices on a Field Controller (FC) bus when third-party devices are present.

• The TMR connects directly to the MS/TP bus of the controller with the controller running in MS/TP mode. • The TMR can support any Johnson Controls or third-party BACnet MS/TP controller. The ZFR18xx radios only work with select Johnson Controls field controllers. -
Page 9: Connected Equipment Gateway
The CEG is a supervisory device that monitors BACnet MS/TP equipment and sends data to cloud- based services. The CEG supports Johnson Controls and third-party chillers. When you use the CEG with a TMR, you can connect the wireless enabled BACnet MS/TP controllers over the TMR wireless mesh network. -

Page 17: Connecting Multiple Tmr Coordinators To A Ceg
The standard CEG Panel provides space to install a second TMR coordinator. You can also mount an additional TMR coordinator external to the CEG Panel, if the equipment is located in separate areas where it is not recommended to extend the mesh, for example, floors, wings, buildings.

Page 18: Connecting The Tmr Wireless Router To A Bacnet Device
You can connect multiple MS/TP controllers to the same TMR router. This is useful if you install the controllers in the same control panel, or in close proximity, so that it is more economical to hard wire the controllers together, rather than to connect a separate TMR to each controller.
