4.3.1 CL modem
On connecting a CL modem, in principle all details for standard modems in Chapter 4.3
(from page 20 onwards) apply. Furthermore however, there are other points to be noted.
For setting the parameters in the volume corrector send the appropriate parameter file
("wpp" file) with a PC or laptop and the "WinPADS" parameterisation software to the
volume corrector via the optical interface. The parameter files are included with
"WinPADS".
The following restrictions apply depending on the connected volume corrector:
1. EK260 with software version from 2.40 and other volume correctors from year of
manufacture 2006 onwards:
These volume correctors can be operated without restriction.
If other bus devices are connected to the CL modem as well as the FE260, you must
assign an unambiguous bus address to the volume corrector. This address is used by the
calling software to select a device.
You can set the bus address of the volume corrector with the "WinPADS" parameterisation
software. Interfaces > Modem > Connection formation > Device address
The address may consist of up to 32 characters (numbers or letters).
2. EK260 with software version from 2.02 to 2.22 and other volume correctors from year
of manufacture 2005 onwards:
If other bus devices are connected to the CL modem as well as the FE260, you must
suitably set the call acceptance time window of the volume corrector. A data call of the
other bus devices is only possible outside of this time window.
3. EK260 with software version up to 2.01.
These volume correctors cannot be called via a CL modem.
4.3.2 Problems during data transfer and solutions
If, after connecting the cables and setting the parameters, the data transmission via the
modem does not work, check the following points:
1. Does the signal "Power" light on the housing cover of the FE260 ?
→
If not, make sure that the FE260 power supply is connected correctly and switched
on.
2. Does the volume corrector indicate the status message "Bat. operat.". (With older
versions message "15" in the status "St.Sy")
→
Connect the terminals "U+/-" of the FE260 correctly to the terminals "Uext+/-" on the
volume corrector.
In addition you can also measure the voltage on the terminals "U+/-" of the volume
corrector with a multimeter. It should be approx. 8.5 V.
3. Does the FE260 have the option "CL interface" ?
→
If so, follow all the instructions in Chapter 4.3.1, page 21.
