Circutor ReadWatt - Optical impulses reading using Readwatt 

There are many meters that have an optical pulse emitter, such as GAS meters or DLMS electrical meters. These optical pulse emitters are frequently used to check the correct operation of counters, but can also be used to obtain meter consumption information, with the advantage that it's not necessary to modify the installation.

In order to take advantage of this functionality, it is necessary to have an Optical Pulse probe, which is placed in front of the pulse emitting LED and captures the consumption information that the meter emits with the same precision as the counter itself.

#Note. This system should not be confused with a communication with the counter database using an optical probe, but only the optical pulse reading.

Necessary hardware:
- Optical pulse probe (CIRCUTOR Readwatt)
- DEXGate2 (compatible with Readwatt) or an electrical pulse counter.

Readwatt optical pulse probe:
The Readwatt converts optical pulses from the meter to Modbus RTU or to electrical impulses. This probe, therefore, supports both DEXGate2 (Modbus) and any equipment capable of reading electrical impulses.

The Readwatt has an RJ45 connector and is supplied with a cable that facilitates the connection of the RS485, power supply or the pulse output. The relationship between signals and colours is as follows:

1: GND	Brown
2: Rx, RS-232	Blue
3: Tx, RS-232	Yellow
4: A(+), RS-485	Green
5: B(-), RS-485	Grey
6: GND	Orange
7: Pulses output	Black
8: Vcc, Auxiliary power supply	Red

DEXGate2 connection:
Connect the cables corresponding to the RS485 of the Readwatt (Green and Grey cables) to the RS485 input of the DEXGate2, and the power cables of the Readwatt (Brown and Red cables) to the power supply.

Connection to an electrical pulse counter:
Connect the electrical pulse output of the Readwatt (Orange and Black cables) to the input of the electric pulse counter.
