EWA1xxC-PO Configuration and Setup Instructions
1 Introduction
EWA1xxC-PO are a range of clip on modules for EW110 and EW171 Series water meters. Meters fitted with this module have two configurable pulse outputs for remote readout. Per meter one module is required.The module is retrofittable at any time, also when the meter is in operation. When the module is in place no other module can be fitted as EW110 and EW171 Series only provide space for one module. Other available modules are M-Bus (EWA1xxC-MBUS) and RF wireless (EWA1xxC-RF). However, this document only includes instructions for configuration of the pulse out module.

GB 2.2 Wiring to PC
Wiring between PC and module is done by a USB cable and programming interface EWA3001797.
Figure 1. Connection of programming interface
The cables are connected as follows:

To wire the module into the programmer normal strip terminals can be used. If a number of modules have to be programmed consider reusable socket terminals, for example Wago type 222 as in above example.

GB 2.3 Installation of Programming Interface
When the programming interface is connected with the PC the driver is automatically installed and displayed as "Silicon Labs CP210x USB to UART Bridge". The COM port used can be checked in the device manager of the PC. In below example it is COM6.
Figure 2. Device manager When the software EWASET-PO has been installed and the module connected it can be parametrised. Parametrisation is not mandatory, if the module is not parametrised standard values are applied (see Chapter 1.5 Standard Values above). The parametrisation software is available for free download in the download area of the RESIDEO metering website under https://homecomfort.resideo.com/sites/Europe/en-gb/Solutions/Metering/Pages/Metering.aspx.

3 Programming
3.1 Wake up
NOTE: This chapter applies only to modules produced before August 2015. After production the module is put into sleep mode to save battery life. Before programming or installation briefly place a magnet near the reed switch of the module. By this the module is woken up from sleep mode.

WP � Forward flow impulse
Only forward flow pulses are sent.
WS � Backward flow impulse
Only backward flow pulses are sent.
PR � Flow impulse
Any flow pulse is sent, regardless of direction.
PT � Forward and backward flow impulse
Only backward flow pulses are sent. Forward flow pulses are compensated by suspending backward flow pulses of same value.
SK � direction state

3.2.2.5 Read configuration Current configuration of the pulse out module is read and shown on the display in a separate window.
Figure 8. Window with configuration information It may take several retries until the configuration window appears. The reason is that the module only checks once per minute if it is connected to a programming interface. Retries are done automatically, standard value is 20 retries, with 5 000 ms time between each retry. 3.2.2.6 COM Port Allows to select the COM port to which the programmer is connected. (Also see chapter 0 above.) Press "Refresh COM" button in case COM port used is not shown in drop down list. 3.2.2.7 Perform When all inputs have been done the data is written onto the module by pressing the "Perform" button.
