DAVE II is a compact system designed to collect readings from meters with impulse output. The
system is comprised of one main controller integrated 4 impulse converters and 4 analog con-
verter with the possibility of connecting other several three-channel pulse converters. The con-
troller is connected to the pulse converters by a two-wire RS485 bus. Readings from the convert-
ers are periodically collected by the controller and saved in an archive. The content of the archive,
current values and configuration settings are accessible through a web interface. Data can be
presented in a graphical or tabular format.

Addition of an IP address (1):
1. Click the area (1)
2. Enter the IP address (the format is ip_address/mask, e.g. 192.168.0.113/24)
3. Click Add
It is possible to add several IP addresses; the device will listen on each of them.
Addition of a network gate (2): analogous to the addition of an IP address
Addition of a DNS server address (3): analogous to the addition of an IP address
Click Save to save your changes or Revert to return to the original settings.
3.3 Modem tab (for devices having a GSM modem)
Enabled: Yes/No, allow/forbid modem connection
PIN: enter the PIN code of the SIM card (uncheck the check box if there is no PIN)
APN: enter the APN name for data connection
Number: Dial-up phone number
Registration status: Registration status: displays the modem registration status
It is possible to use DHCP together with statically configured IP addresses. In such a case the
device listens on both the statically configured IP addresses and the address obtained from the
DHCP server.

Provider: the provider where your DDNS service is registered
Login: account login for the account at the provider
Password: password for the account
Retype password: password for the account, again
Hostname: the dynamic domain name
Update period [m]: the time period for updating the IP address on DDNS servers

4. Configuration setup
After clicking “Configuration”, login is required (only users with administrative privileges will be
granted access, see Section 3.1).
The Configuration setup allows to configure converters and related parameters. A Dave II module
integrates 4 impulse converters (PDImp; used with meters with impulse output) and 4 analog
converters (PDLoop; used with meters with 4 to 20 mA current loop output). It is possible to con-
nect additional external PDImp and PDLoop converters over an RS-485 bus.
The configuration dialog allows addition and removal of PDxxxx modules and changes of their
parameters.

14
4.1 Adding a new PDImp module
1. Click on the folder icon
2. Click “Add”
3. Click on name
5. A configuration dialog opens
6. Enter description, say, “TestImp”
7. Enter the converter modbus address, see Section 1.2.
8. Click “OK”
9. The module we have added is displayed in the list of modules
10. Click “Save”
11. After adding all the modules you have to click “Reconfigure”
PDImp485 (system) - external PDImp converter (3 impulse channels)
PDImpInternal (system)- integrated PDImp converter (4 impulse channels)
4. Choose an external or internal converter

15
4.1.1 Adding a new channel to a PDImp module (pulse meter converter)
1. Click on the name of the module for which you would like to add a channel.
2. Click on the item in the list
3. Channel configuration dialog opens
Description: the description of the channel, say, “impulzný výstup”
Channel index [0 - 2]: the number of the input connected to the ouput of the pulse
meter
Engineering unit: the measuring unit, for instance, kWh
Number of impulses per one engineering unit [0 - 1000000] (imp/eu): determines
how many pulses count as one engineering unit
Archivation period [1 - 3600] (seconds): how often the data are archived
4. Click “OK”
5. Add more channels (up to three) or continue by clicking “Save”
6. After you changes are finished, click “Reconfigure”
7. The added channel shows up in a list. After clicking on inputs it is possible to set display
parameters

4.1.2 Adding a plot of measured values to a PDImp channel
The collected meter readings can be represented graphically. There are two types of plots to
choose from: consumption plot and current value plot. The consumption plot reflects the number
of pulses measured. The current value plot is obtained as a derivative of the number of pulses
measured.
1. Click on the name of the channel for which you want to add a plot
2. Click “Add”
3. Select the type of plot
4. A configuration dialog opens
Fill in the description and the number of decimal places to display.
Description:
Number of decimal places to display [0 - 20]:
5. Click “OK”
6. Click “Save”
Adding a plot Current value plot is almost the same as adding a plot Consumption value.
Dierence is in configuration of a plots.

17
Fill in the description of the plot and the number of decimal places to display. For a
current value plot, you also have to fill in the engineering unit and the corresponding
conversion factor. If unsure about this, click “Help”
Let the engineering unit for consumption be cubic meter [m3]. The derived unit for cur-
rent value would be cubic meter per second [m3/s], but we want to display it in liters
per minute [l/min]. Since 1 [m3/s] = 1000 [l/s] and 1[ l/s] = 60 [l/min], we have 1 [m3/s]
= 60000 [l/m]. Our conversion factor is 60 000.

the top of the range
Example: 4 mA at the output of the meter corresponds to flow of 0 [l/s], 20 mA cor-
responds to flow of 150 [l/s]
Archivation period (seconds): how often the data are archived
