An EPROM of the type 27C512 is used to store the firmware for the SCAMAX 2600/4000. The firmware
can be exchanged or updated by changing the EPROM. Firmware is downward compatible, which means
newer firmware will be fully functional with older hardware versions.
The EPROM label shows the firmware version as well as the camera and controller type.
Example:

An EEPROM stores parameter values by busing the service program. As well, it stores the corrections
values after a white calibration has been executed for both scanner modules.
The RS232 (10-strand ribbon cable) of the external interface to the PC, is connected to X8 as shown.
In case of a SCSI scanner, the cable from the SCSI board is connected to X9.
X7 is only used in the SCAMAX 4000 and older SCAMAX 5000 scanners.
