4.4.1 Reading out and parameterising the volume corrector
This is the standard operating mode for the local interface in which a volume corrector
connected to the FE260 can be read out and parameterised.
In this respect the switches S1 and S2 on the local interface board must be set to
"normal".
In contrast to the optical interface on the volume corrector itself, the FE260 local interfaces
can only be used under the following conditions:
•
For reading out and parameterising the volume corrector with an AS-200 Readout
Device, it needs at least the version 8.41. In the AS-200 set the parameters "alternative
baud rate" and "alternative data format" precisely as with the volume corrector for the
parameters "Bd.S2" or "DF.S2".
•
For reading out or parameterisation with a PC or laptop the "WinPADS"
parameterisation program must operate without baud rate changeover. In this respect
the so-called "local connection" must be set. (
→
"Setup" / "Interface..." / "Establishing a
connection" / "Local connection").
If WinPADS does not offer you this setting, you need a later version of the program.
(Update available, for example from http://www.elster-instromet.com).
4.4.2 Parameterisation of the modem integrated into the FE260
When the switch S2 is set to "Modem par.", the modem integrated into the FE260 can be
parameterised with the aid of a PC or laptop. The serial interface of the PC or laptop is in
this respect connected to the optical interface or to the DSUB-9 connector. The modem
parameterisation can then be carried out, for example, with the aid of the program
"Modemini".
The modem parameterisation should only be carried out by experienced specialist
personnel. In cases of doubt obtain the help of a service technician from Elster-
Instromet.
4.4.3 Test mode
Switch S1 in the "Test" position activates the test mode: The data sent by the modem and
the volume corrector is output simultaneously on the transmitted data line of the optical
interface and the RS-232 (DSUB-9 connector).
In this operating mode the communication between the integral modem and the connected
volume corrector can be observed with the aid of a so-called "terminal program". This
function can be used by experienced specialist personnel for putting the FE260 into
operation.
The test mode is signalled by a red indicating light (LED) on the interface board.
