output signal). Manual operation is available for the analog output of the meter and is programmed using
parameters 9: outA , chapter 10, Table 10. Also, the output can be configured for quick (unconditional) manual
mode controlled by the BIN binary input, by programming parameter 15: Func for the value hAnA (chapter 9).
The preset value of the manual mode (parameter
12: HSEt ) can be set directly using the [UP] or [DOWN] button or
using the quick menu (chapter 11), or alternatively, in the parameter configuration mode (from the film keypad of
the meter or remotely using the RS485 or PRG serial port, chapters 10, 14 ÷ 16 ).

14. CONNECTING THE CONTROLLER TO A COMPUTER AND AVAILABLE SOFTWARE
It may be useful (or necessary) to connect the meter to a computer in the following situations:
- remote monitoring and recording of current measurement data and control of the status of the analog output
- quick configuration of parameters, to include copying of settings to other meters of the same type
In order to establish communication over long distances, it is necessary to establish a connection in the RS485
standard with an available port in the computer (directly or using an RS485 converter), as described in chapter 15.
Moreover, as a standard, the meters are equipped with a PRG port which enables connecting to a computer using
an AR955 programmer (without galvanic separation, cable length approx. 1.2 m). Both the programmer and the
RS485 converter require installation of the supplied serial port drivers on the computer.
Communication with devices is effected using a protocol compatible with MODBUS-RTU (chapter 16).
The following applications are available (on a CD supplied with the AR955 programmer or to be downloaded from
the Internet at www.apar.pl, Download section, for operating systems Windows 2000/XP/Vista/7/8):

display of current measurement data from the connected device
- configuration of the type of measurement input, the indication range, the alarm options
display communication, and access options, etc. (chapter 10)
- creation of a disk with a "cfg" extension, containing the current configuration
of the parameters to be used again (duplication of configuration)
- the program requires communication with the meter via the RS485 or PRG (AR955) port
