SAM4s ER-900 Series Operator's & Programming Manual v.1.28 S-Mode Programming • 109
Flash ROM Updates
The ER-900 register software is loaded in Flash ROM. This program may occasionally be
updated by the manufacturer. Your SAM4s dealer can update the software if necessary.
The Flash ROM can be loaded through by SD card or by using a PC Update Program
(NEWNET_DOWN.exe.)
NOTE: The flash ROM program file name was changed to from NEWNET.bin to
ER900.bin beginning at version 1.030.
CAUTION: Flash ROM update by either method must be done by a qualified, trained
technician. DO NOT POWER OFF OR ABORT any program loading once it has
started. Failure to follow the procedures exactly may cause the register to fail
completely.
Flash ROM Update by SD
The ER-900 Flash ROM program is contained in a file named ER900.bin. This file will be
provided to the authorized dealer by CRS, Inc. and contains both the Boot program area and
the Application program area.
1. At your PC, format the SD Card for FAT32. (See the “Note: If you are Using an
SD Card for the First Time . . . " on page 104.)
2. Create a folder named update in the root of the SD card.
3. Copy ER900.bin to: SD:/update/.
4. Insert the SD card into the register. (The SD slot is located inside the printer
compartment. Remove the security screw and open the flap securing the SD slot.
Insert the SD card until you hear a click and the SD card is locked in.)
Boot Area Update
1. Insert the key marked “C” and turn the control lock to the S position (the
unmarked position clockwise from “P”.)
2. Power off the ER-900.
3. Press and hold the Numeral 1 key on the keyboard. While continuing to hold the
Numeral 1 key, turn on the power switch. Immediately, a beep-beep-beep is
heard.
4. Release the Numeral 1 Key.
5. The display will flash, slowly at first. After a few seconds a rapid beep-beep-
beep will be heard again, and the display will flash rapidly (after version 1.022
the display will stop flashing to indicate the update is complete.) The boot
update is now complete.
6. Turn the ECR power switch OFF and proceed directly to the next step:
Application Update.
