Nr. Parameter Name
20 Next parameter
(21st) uses EEPROM.
21 ..channel 1 (offset/
(22nd) gain)
22 ..channel 2 (offset/
(23rd) gain)
23 ..channel 3 (offset/
(24th) gain)
24 ..channel 4 (offset/
(25th) gain)
*1 To RESET the special function block, set both parameters (6&7) to "reset module".
While processing a RESET command, no other parameter will be accepted by the
special function block.
As mentioned in the FX
not possible to RESET the special function block to defaults and set the BFMs 0 to 24 to
a value different to the default value with the same parameter data block.
However, it is possible to send a parameter block to RESET any special function block
that supports the RESET function and afterwards to send a second parameter block to
set the module/s to the desired parameter values.
*2 In this case the default value of the GSD file (high speed) differs from the hardware
default value (normal speed).
*3 The changes of BFM # 0 are written to EEPROM memory. Keep a delay of 300ms
between setting the input range and other write accesses to the EEPROM.
