Getting Started
To begin development with the µFlashTCP-EP, you will need a PC compatible computer with a
telecommunications program and a free serial port. Connect the µFlashTCP-EP’s 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 µFlashTCP-EP, using our A/C adapter PN
70-0005 or a source of unregulated DC between 7 and 34 Volts,
capable of supplying 2 Watts. Observe the polarity indicated on
the panel silkscreen.
The µFlashTCP-EP 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 µFlashTCP-EP,
remove the serial cable from J2 and jumper pins 2 and 3. 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 µFlashTCP-EP’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 µFlashTCP-EP, the next step is to try to upload a
file. This is the procedure for getting a file from your PC to the µFlashTCP-EP. On the
µFlashTCP-EP, type the command
UP
followed by the name of the file you wish to upload. The
µFlashTCP-EP 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.
If the transfer terminated without problems, you have a working development environment for
the µFlashTCP-EP controller. At this point, you may wish to download the files
EDIT.COM
and
BASIC.COM
from the µFlashTCP-EP to your PC. Start the download on the µFlashTCP-EP by
typing
DOWN BASIC.COM
and pressing Enter. On your PC, begin the transfer, usually by
pressing PgDn. After the file is transferred, repeat the process with
EDIT.COM
. These files are
also found on the JK microsystems web site.
The µFlashTCP-EP does not have a hardware clock calendar. The time and date will be
maintained by DOS until the power is cycled. If the correct time and date are required after a
