6.2 Firmware Programming
The internal firmware is field programmable in the RCP redundant controller. This
section details the procedure required to load new firmware into the RCP controller.
6.2.1 Hardware Interface
A connection from J6 of the controller and the parallel (LPT1, LPT2 or LPT3) port of a
host PC must be established. This port must be configured for EPP/ECP or bidirection-
al mode. Connect using an IEEE-1284 Compliant cable (DB25 Female – DB25 Male
straight through. This cable is available for purchase in most electronic supply stores).
The PC should be running Windows OS (98, NT, 2000 or XP are supported).
6.2.2 RCP Flash Upgrade
Use RCP Flash Upgrade only if a new official copy of firmware is released. Contact the
Paradise Datacom U.S. office if you need to upgrade your unit's firmware.
The RCP firmware can be easily updated from the user's PC. A valid copy of the
firmware HEX file must be obtained from Paradise Datacom’s U.S. office.
The following files will be provided for the firmware upgrade:
• _code.zip: this zip file contains the programmer software (avreal32.exe); firmware
hex file (~code.hex); executable batch files (prg_LPTx.bat). prg_LPT1.bat for LPT1
prg_LPT2 for LPT2 and prg_LPT3 for LPT3
• dlportio.zip: this zip file contains the parallel port drivers required by Windows OS.
• DisableWarmBoot.reg and EnableWarmBoot.reg - Parallel port behavior manage-
ment utilities.
Step 1: Unpack dlportio.zip onto the target PC. Run the file, Setup.exe.
Step 2: Run DisableWarmBoot.reg. Select OK to add Windows registry key. The key
will forbid the Windows parallel port driver from scanning parallel port after system re-
boot. Reboot the computer.
Step 3: Unpack _code.zip into a temporary folder on the PC (for example, C:\temp).
After the files are unpacked, locate the \_code subfolder.
Step 4: Turn off the RCP unit. Connect the PC’s LPT port to the Program Port (J6) at
the rear of the unit using an IEEE1284 compliant cable (a “straight-through” DB25 fe-
male to DB25 male parallel cable). Turn on the unit’s power.
