Getting Started
To begin development with the Flashlite, you will need a PC compatible computer with a
telecommunications program and a free serial port. Connect the Flashlite’s Debug/Console Port
to the PC’s serial port with a 9-pin serial cable (straight through wiring). Run the
telecommunications program and configure the serial port for 9600 baud, 8 data bits, 1 stop bit
and no parity. Apply power to the Flashlite, using our A/C adapter PN 88-0006 or a source of
unregulated DC between 7 and 34 Volts, capable of supplying 2 Watts. Observe the polarity
indicated on the board silkscreen.
The Flashlite should respond with a welcome message and a B: prompt. Enter
DIR
to look at the
directory of drive B:. If you do not get a welcome message or echo of the characters that you
type, you need to check your serial port setup. To test everything but the Flashlite, remove the
serial cable from J6 and jumper pins 3 and 5. If characters typed on the keyboard are not echoed
on the screen, the problem is with your setup. You must resolve the problem before you can
continue.
If you were able to do a
DIR
, take a few minutes to explore the contents of the Flashlite’s file
system. You will find all of the essential utilities on drive A: and some optional programs on
drive B:. Drive A: is write-protected and cannot be altered. Drive B: is read/write and can be
changed or reformatted.
After you have looked at the programs on the Flashlite, the next step is to try to upload a file.
This is the procedure for getting a file from your PC to the Flashlite. On the Flashlite, type the
command
UP
followed by the name of the file you wish to upload. The Flashlite will begin
sending characters to your PC polling it for the file.
On your PC, start the transfer, usually by pressing the PgUp key. The telecomm program should
respond by requesting the file name and protocol. Enter the file name and select X-Modem for
the protocol. The transfer should start and when it is complete, you should get a new B: prompt
on the screen. If the transfer does not work, the problem is most likely the Carrier Detect signal
(pin 1 on the DB-9 connector) into the PC being sensed as low or false. Make sure that the signal
is at least +3 volts into your PC if you are not able to transfer files.
