1 GETTING STARTED
Thank you for buying the NMIN-0803-Mini. We hope you will find the NMIN-0803-
Mini to be the incredibly useful small controller board we intended it to be, and easy to
use as possible. If you are new to the NMIN-0803-Mini, we know you will be in a hurry
to see it working. That’s okay. We understand.
Figure 1 – NMIN-0803-Mini
Let’s skip the features and get right to the operation. Once we’ve got communications,
then we can make some lights blink and know for sure that we’re in business. Let’s make
this “Mini board” talk to us!
We’ll need PC running a terminal program. Then we’ll need a serial cable to connect
from the PC to the NMIN-0803-Mini (which, hopefully, you’ve already gotten from us).
Then we need power, such as from a 6VDC wall transformer (which, hopefully, you’ve
NMIN-0803-Mini User Manual 5

already gotten from us. If we have those connections correct, we will be able to talk to
the NMIN-0803-Mini interactively.
The wall transformer can supply the power to the NMIN-0803-Mini board, but do not
connect it to the board yet. The board can be seen in the figure below, showing the
connections of VIN and GND. Connect the serial cable between the J7 connector and the
PC. The J7 upper row pinout can also be seen in the figure.
Figure 2 – Power and Serial Connections
Once you have your serial cable and connectors, and wall transformer and connectors
ready, follow these steps.
Start with the PC. Install (if not already installed) and run the terminal communications
program - MaxTerm or NMITerm or HyperTerminal. Set the program for the desired
communications channel (COM1, COM2, etc.), and set the communications parameters
to 9600, 8N1. Operate the program to get past the opening setups and to the terminal
screen, so it is ready to communicate. (If necessary, visit the section on PC
Communication if you have trouble understanding how to accomplish any of this.)
Hook the computer end of the serial cable (usually a DB-9 connector, but may be a DB-
25, or other, on older PC’s) to the PC’s communication channel selected in the terminal
program. A simple serial cable can be made with Digikey part CFP09T-ND (a female D
sub 9), CSC10T-ND (a 10 pin female connector), and a short length of 10 circuit ribbon
cable.

Figure 3 – The Serial Cable
Plug the wall transformer into the wall, but do not plug it into the board yet.
Figure 4 – The Power Cable
1.1 Instructions for IsoMax Users
Now, while watching the LED’s plug in the wall transformer connector to the power pins
on the NMIN-0803-Mini board. Be very careful not to plug it in reverse polarity here,
even though the regulator, LM2937 has the reverse voltage protection.
Both the Red and Green LED’s should come on. If the LED’s do not light, unplug the
power to the NMIN-0803-Mini quickly.
NMIN-0803-Mini User Manual 7

Figure 5 – The LEDs
If the LED glows, then check the screen on the computer. When the power is applied,
before any user program installed, the PC terminal program should show,
“IsoMax™V0.5”
(or whatever the version currently is, see upgrade policy later at the end of this chapter),
or “© 2000-2001 Motorola Inc. S-Record loader. Version 1.3” .
If the LED’s don’t light, and the screen doesn’t show the message, unplug the power to
the NMIN-0803-Mini. Check the power connections, particularly for polarity. (This is the
most dangerous error to your board.) If the LED’s come on but there is no
communication, check the terminal program. Check the serial connections, particularly
for a reversal or rotation. Try once more. If you have no success, see the trouble shooting
section of this manual and then contact technical support for help, before going further.
Do not leave power on the board for more than a few seconds if it does not appear to be
operational.
Normally at this point you will see the prompt on the computer screen “IsoMax™ V0.5”,
or “© 2000-2001 Motorola Inc. S-Record loader. Version 1.3”. Odds are you’re there.
Congratulations! Now let’s do something interactive with the NMIN-0803-Mini.
To start with IsoMax programming, in the terminal program on the PC, type in, “WORDS”
(all in “caps” as the language is case sensitive), and then hit “Enter”. A stream of words
in the language should now scroll up the screen. Good, we’re making progress. You are
now talking interactively with the language in the NMIN-0803-Mini.
Now let’s blink the LED’s. Port lines control the LED’s. Type:
REDLED OFF

To turn it back on type:

Now let’s use the Green LED. Type:
GRNLED OFF

Now you should have a good feeling because you can tell your NMIN-0803-Mini is
working. It’s time for an overview of what your NMIN-0803-Mini has for features.
First though, a few comments on IsoMax™ revision level. The first port of IsoMax™ to
the NMIN-0803-Mini occurred on May 27, 2002. We called this version V0.1, but it
never shipped. While the core language was functional as it then was, we really wanted to
add many I/O support words. We added a small number of words to identify the port
lines and turn them on and off and shipped the first public release on June 3, 2002. This
version was V0.2. Currently we are shipping V0.5 . As we approach a more complete
