MC3 FLASHLOADER PROGRAMMING (APPLICATION UPGRADE)
This instruction details the procedure to use when loading (new or revised) application firmware
into the Flash EPROM of an MC³ Controller. It is recommended you use a Merrick Programming
Kit (S60234-1), which consists of a serial cable, memory SIMM, application and firmware. A
straight
serial DB9-P to DB9-S cable between the serial port on the PC and COM 2 serial port on
the MC³ Controller must be used. See Figure 1 on next page.
FLASHLDR.EXE is a DOS application, running on your PC, used to load the MC³ application
(HEX file) into the MC³ Flash EPROM. It must be started from the directory that contains the HEX
file you want to load. FLASHLDR.EXE cannot be used from a network drive.
The PC serial port must be native to the PC. USB serial adapters will not work.
The usable baudrate depends on the CPU speed and operating system. For DOS, Windows 95,
98 and ME, use 38400 or 57600 baud. For Windows 2000 and XP, you may have to go as low as
4800 baud.
A
1 to 16 Mbyte 72 pin SIMM must be connected into the SIMM socket on the CPU board before
installation of application software. After programming the MC³ controller the SIMM memory must
be removed.
NOTE: There are 2 procedures; choose the procedure that matches your CPU Board revision.
NOTE: Do not erase other programs in flash memory unless specified to do so by the factory.
CAUTION: It is recommended to turn off power and remove the power cord from the controller
before setting or removing the JP1 jumper, changing position of SW1 and inserting and extracting
the SIMM.
