ER-5200M/5240M Electronic Cash Register S-Mode Programming • 89
Updating Firmware Program
The ER-5200M/5240M firmware program is loaded in flash EPROM. Occasionally, CRS/SAM4s may
provide updates to the firmware in order to fix bugs and/or update the register feature set. The
firmware program can be transferred from a PC to an ER-5200M/5240M through the register’s RS-
232C ports.
Note: There are two parts to the firmware program: Boot area and Program area. In most
cases, you will only need to update the program area. You will be notified where updates are
required.
