1 = read Eprom
2 = write Eprom data into Ram (1Byte = 7 Bit)
3 = read Eprom data (1 Byte = 8 Bit)
4 = erase Eprom data
5 = program Eprom
0x2A 42 6..0 Eprom Data 512 k must be written. Data is sliced to 7 Bit, which are
reconciled in the sensor to 8 Bit
0x7F 127 Dummy Register No operation
* each access to the register triggers the function. It is not required, and it makes no sense to write any value to the
register. Simply calling the register address makes the necessary function work.
The register 0x11 selects the content of the status register. The status register has the parameters temperature of
sensor head, register contents, version of electronic system and camera, operating hours counter, on counter, digital
inputs, version of EPROM Firmware and 32 Bytes EPROM data, serial umber, scan range geometry. This method is
valid for Ethernet Scanners, ISA board and i-Control.
Special register 0x18 (24)
The special register 0x18 allows to query sensor data direct. When a value smaller than 127 is written to the register,
the read out of the FiFO is stopped and the register is put to the data bus. The number of the register is the content of
the special register. Data will remain on the bus as long as the special register is written again with 127. Then normal
image transfer is possible again.

Control register
NC Shows the content of all control registers. Except
Registers which act as „impulse switch“ like „Reset
Sensor“ - unused Registers and Bits give back a “0”
