DTS 307 AC Revenue Grade Meter

DTS 307 is a Revenue Grade Meter (RGM) that can connect to Tigo's Cloud Connect (CC) or Cloud Connect Advanced (CCA). Other DTS meters from Measurlogic can connect to the CC/CCA as long as they are equipped with Modbus RTU RS-485 communication protocol. Those models include:

  • DTS 307
  • DTS 310
  • And others, click here to view list

This article is going to focus on model DTS 307 that is sold as a kit along with the CCA. Instructions will mention CCA, but are applicable for CC as well.

Wire the DTS 307 RGM to Tigo CCA

Measurlogic DTS 307 meters have their Modbus RTU RS-485 connection at the bottom of the device, port name "RS-485", see figure 1.


Figure 1: Left 3 connections of the RS-485 port on the bottom of the DTS 307 meter needs to be connected to the CC or CCA 

Connect CCA RS-485 port (either RS485-1 or RS485-2) to RS-485 port of the DTS307 meter(s) as described in figure 2.

Note: old versions of CC may refer to the RS485 port as "optional", nevertheless notation remains the same as in figure 2.

Configure the DTS 307 RGM

DTS 307 comes with the following factory settings:

  • Modbus Address: 100
  • Baud Rate: 9600
  • Parity: None
  • Stop Bits: 1

Up to 1 DTS 307 device per Tigo's CCA RS-485 ports can be installed without configuration (i.e., without changing those factory settings). For example, 1x DTS on RS-485 (1) and 1x DTS on RS-485 (2). However, in case there are 2 or more DTS meters on the same port, for example: 2x DTS on RS-485 (1) (as illustrated above in figure 2), device configuration is needed for the DTS.

Configure a DTS 307 (required when more than 1 device is installed per RS-485 port):
