Printer Port Not Found Message
Specified the wrong port address
The software could not find a printer port at the specified address. Try another address. The command line
programs use a /Pxxx parameter to select the port address. Quickloader uses pull-down selections. The
most common addresses are 378, 278 and 3BC. Also verify that the attached emulators are powered up.
Un-powered emulators could prevent the software from seeing the port itself.
Using the wrong software
Under NT and Windows 2000 Professional, you MUST use the 32bit software. These include Quickloader
and all command line programs that end in ‘32’. These programs all use our ring-0 drivers to access the
printer port hardware. Win95, Win98 and ME users may user either the 16bit or 32bit versions of these
programs. Win3.1 and DOS users must use the 16bit versions. We do not provide a 16bit GUI application
for DOS or Win3.1.
No Emulator(s) Found
Specified an existing but incorrect printer port.
This error message indicates that the specified port was found, but no emulators were found at that port.
The emulators might be plugged into a different port. Change the port selection to specify the correct port
or move the download cable to the specified port. The most common printer port addresses are 378, 278
and 3BC. If you are using the command-line loaders, use the /Pxxx parameter to specify the port.
Using wrong download cable or backshell
The FlexROM III download cable is compatible with the EconoROM III and the older FLexROM II
product but is NOT compatible with EconoROM II or earlier FlexROMs. Use the cable provided with
FlexROM III.
Transfer speed set too high for this port (16bit loaders only).
The 16bit software is capable of over-running some printer ports. You may need to reduce the speed to
achieve reliable operation in these situations. The RTTEST16 program verifies transfer reliability. Test the
desired transfer speed reliability with “RTTEST16 /dx” (where x is 0,1,2,3 or 4). /d0 is the fastest
setting.
If you are daisy-chaining several emulators, their combined load can slow down the printer port rise times,
resulting in a need to slow down the transfer speed to avoid over-running the port signals. Run the
RTTEST16 program with the emulators daisy-chained together to properly reproduce the eventual working
environment.
One or more Emulators not powered up.
FlexROM III draws its operating power from the target’s EPROM socket or an optional external power
supply. The target must be powered up or the external power supply connected during all load or verify
operations. If multiple emulators are daisy-chained, they must ALL be powered up to talk to ANY of them.
