ER-5215M Electronic Cash Register v2.4 S-Mode Programming • 85
Updating Firmware Program
The ER-5215M 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-5215M 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.
