Communication via radio
The integrated radio function is an interface for communication of predefined protocols with
Hydrometer radio receivers. The communication protocol is preset, but can be defined to a customer-
specific protocol using the IZAR@SET software. By default, the internal radio is disabled. When the
meter detects a flow, the integrated radio is enabled. If the meter detects a flow without an interruption
at least 3 hours, the radio stays on, otherwise it is switched off again.
RS-232 module
The RS-232 communication module is a serial interface for communication with external devices, e.g.
a PC. The transmission speed is 300 or 2400 baud. A special data cable is required for connecting this
module to the PC. (Order no.: 087H0121)
RS-485 module
The RS-485 communication module is a serial interface for communication with external devices, e.g.
a PC. It can only communicate at a transmission speed of 2400 baud.
L-Bus module
The L-Bus communication module is a serial interface for communication with an external radio
module, in which the M-Bus protocol is transmitted. It can be used for example if the radio range of the
internal radio is not enough.
3.6.2 Function modules
Pulse output module
This module contains connections for two pulse outputs, which can be programmed as desired using
the IZAR@SET software. The energy pulse output is marked as standard as “01 -
┴
” on the module
and “Out1” in the display. The volume output is marked as “02 -
┴
” on the module and “Out2” in the
display.
Pulse input module
This module has 2 pulse inputs for connecting 2 additional pulse meters, such as water meters, gas
meters or electricity meters. The possibility of programming the pulse value using the IZAR@SET
software enables volume or energy values to be displayed and transmitted remotely over a suitable
communication module. Initial meter counts can also be parametrized for these two pulse inputs.
Module IN-OUT
The Module IN-OUT is equipped with two pulse inputs and a pulse output, which can be programmed
as desired using the IZAR@SET software. Pulse input 1 is marked “I1 -
┴
” on the module and “IN1” in
the display, pulse input 2 “I2 -
┴
” on the module and “IN2” in the display. The pulse output is marked
“01 -
┴
” on the module and “Out1” in the display. The pulse output on this module is not galvanic
isolated.
Analogue module
The analogue module has the size of 2 standard modules and has two 4-20 mA outputs. If an
analogue module is mounted in the meter, no other module can be installed. The internal radio is still
working. The connection cable between the main pcb board and the module has to be installed on port
1 (left slot). By default, the two analogue outputs are not programmed, the values can be programmed
with the IZAR@SET software (standard version).
