ICOM-manual

First steps

Power supply

The ICOM-200/201 uses a power supply with 8-12 VDC, 1A. Minus is placed
on the pin of the power supply connector. The current consumption is,
depending on the application, up to 400mA.

PC mode

After a reset or power-down the Tiny-Tiger® inside the ICOM-200/201 is
testing if the PC mode pin is „low“. In this case, the ICOM switches to PC
mode/Debug mode. Is the pin „high“, the ICOM starts in run mode. The time
between power-on and first activity on the I/O pins is approx. 230 msec.

To set the ICOM-200/201 to PC mode, a reset or power-down is needed.
Setting the DIP switch to PC mode while in run mode is not sufficient.

Wilke Technology GmbH • 0241/918900 • http://www.wilke.de/ • [e-mail]

2-2

ICOM-200 / 201

RUN mode

If the DIP-switch “PC/Run” is in position “Run”, the program in the ICOM­200/201 is executed immediately after a reset. Debugging is not possible in
this mode.

Program download

A program created with the Tiger software is downloaded into ICOM-200/201
through the 9-pin Sub-D connector. To download the following has to be done:

Connect a power supply 8-12 V DC (Polarity: Inner contact = minus,

outer contact = plus)

Connect ICOM-200/201 and PC with 9-pin D-Sub cable
Set DIP switch of ICOM-200/201 to PC mode
Set the reset DIP switch to „Reset“ and back to original position
Start download at the PC.

ICOM-manual

SLEEP mode

The ICOM-200/201 can be put into sleep mode if the Tiny-Tiger® inside has a
real time clock. In sleep mode the power consumption of the ICOM-200/201 is
descreased significantly to just approx. 25mA. While in sleep mode, no BASIC
program is executed by the ICOM-200/201.

Sleep circuit

®

The internal clock and SRAM of the Tiny-Tiger
Goldcap. The power consumption of clock and SRAM is approx. 70µA, with a
fully loaded Goldcap this is enough for about 3 hours.

To use the SLEEP mode of the ICOM-200/201 Jumper J9, which is located
under the LC display, has to be drawn. On delivery the jumper is inserted, so
SLEEP mode is disabled.

are buffered through a

ICOM-200 / 201

To put the ICOM-200/201 into sleep mode, the alarm time for the Tiny-Tiger
clock has to be set. Following that the ICOM-200/201 falls into sleep mode
and wakes up again at alarm time. More detailled information on how to set
the alarm time can be found in the BASIC-Tiger

If jumper J9 has been drawn and the Goldcap is unloaded, it takes about
30 seconds from connecting the power supply before the ICOM-200/201
switches on.

Keyboard

The ICOM-200 has a 20 key matrix keyboard. The keyboard is devided into
two blocks. The first block has four vertically arranged keys placed directly on
the right side of the LC display. Those keys can e.g. be assigned to a menu
on the LC display. The second block consists of 16 labeled keys.

Reading the keyboard is done with the device driver „LCD1.TDD“. The
following example scans the keyboard and gives back a numeric code for the
pressed key. Additionally a character can be assigned to the numeric code.
Read the „Device driver“ manual of the BASIC-Tiger

®

on how it is done.

With a physical offset of –10h the keyboard culumns are at the addresses 19h
to 27h. In order to scan the keyboard, the following settings have to be
implemented into the program.

LC display

The ICOM-200 has a graphic LC display with a resolution of 128 x 64 pixel.
There’s a special device driver to control this display. By using this device
driver it is possible to control the LC display with simple BASIC commands.

2

Detailled information about usage of this device driver „LCD-6963.TDD“ is part
of the „Device driver“ manual of the BASIC-Tiger

®

.

The LC display has LED backlight. The backlight’s power consumption is
approx. 250mA. Power supply is 5V. To save energy backlight can be turned
off by software. For this Tiger pin P86 is used. Setting the pin to „1“ activates
the backlight, when set to „0“ backlight is off.

ICOM-200 / 201

Serial Interface

As a standard the ICOM-200 and ICOM-201 have two serial interfaces. From
these the port Ser0 can by choice be configured as RS232 or RS485
interface. The port Ser1 always is a RS232 interface. In PC mode this port is
used for downloading the program into the ICOM 200/201. In Run mode it can
be used as a usual RS232 interface.

Detailled information about the serial interfaces can be read after in the
BASIC-Tiger

RS232

Serial port 0 can be configured as RS232 interface with three easy steps:

Remove IC12 from its socket
Please IC3 (MAX232) into the appropriate socket
Set the 4-channel DIP switch S1 to RS232.

®

„Device driver“ manual.

2

Attention: Never place IC3 and IC12 at the same time, as this could

lead to destruction of port 0 !!!

The pins of serial port 0 are located on the DB-37 connector:

RS232 DB-37

TXD0 (Output) 16
RXD0 (Input) 17
RTS0 36
CTS0 35

RS485

The configuration of port 0 as RS485 interface is done by removing the IC3
(MAX232) and placing the IC12 (SN75176) into the 8-channel DIL socket. The
DIP switch on the left side plate of the ICOM-200/201 has to be set to RS485.

Removing or placing the ICs is only allowed without power supply.
Never place both ICs at the same time, this could lead to the destruction
of the ICOM-200/201.

ICOM-200 / 201

Opto inputs

The ICOM-200/201 has eight optocoupler inputs suited for an input voltage
range of 5...12 VDC. To use higher input voltages, as 24V for example, an
additional serial resistor in the input line is used. The resistor value is selected
in accordance to 4...50mA input current needed for the logical “1” level.

The internal resistance is 680 Ohm / 0,25 W. If now another input voltage is
needed, the totally required resistance can be calculated with the following
formula:

2

= (UE-1,3V)/I

R

ges

I
R

Example:
Is e.g. an input voltage of 24 V with a current of 10 mA wanted, you get

from the above formula R
680 Ohm resistor has be replaced with a 2200 Ohm resistor (rounded to
norm value), or a resistor of 1500 Ohm has to be connected in series.

The optocoupled inputs are realized as extended inputs of the Tiny Tiger.
They can be accessed under logical port address 11h (physical 1).

Both USER_EPORT instructions in the sample program are urgent.

ICOM-200 / 201

Power outputs

The power outputs of the ICOM-200/201 are extended outputs of the Tiny-

®

, which are equiped with a driver IC type TD62083 or compatible. The

Tiger
outputs have the physical address 00h and can be (with an offset of –10h)
accessed with the port address 10h by the software.

The power outputs are lead to the 37-ch. Sub-D connector. The pin OVCC is
connected to a internal protector diode, so the outputs are secured against
overvoltage. This pin normally should have the same voltage potential as the
voltage to be switched.

First steps

Power supply

The ICOM-200/201 uses a power supply with 8-12 VDC, 1A. Minus is placed
on the pin of the power supply connector. The current consumption is,
depending on the application, up to 400mA.

PC-Mode

After a reset or power-down the Tiny-Tiger® Economy inside the ICOM-241 is
testing if the PC mode pin is „low“. In this case, the ICOM switches to PC
mode/Debug mode. Is the pin „high“, the ICOM starts in run mode. The time
between power-on and first activity on the I/O pins is approx. 230 msec.

To set the ICOM-241 to PC mode, a reset or power-down is needed. Setting
the DIP switch to PC mode while in run mode is not sufficient.

ICOM-241

RUN mode

If the DIP-switch “PC/Run” is in position “Run”, the program in the ICOM-241
is executed immediately after a reset. Debugging is not possible in this mode.

Program download

A program created with the Tiger software is downloaded into ICOM-241
through the 9-pin Sub-D connector. To download the following has to be done:

Connect a power supply 8-12 V DC (Polarity: Inner contact = minus,

outer contact = plus)

Connect ICOM-241 and PC with 9-pin D-Sub cable
Set DIP switch of ICOM-241 to PC mode
Set the reset DIP switch to „Reset“ and back to original position
Start download at the PC.

ICOM-manual

Opto inputs

The ICOM-241 has eight optocoupler inputs suited for an input voltage range
of 5...12 VDC. To use higher input voltages, as 24V for example, an additional
serial resistor in the input line is used. The resistor value is selected in
accordance to 4...50mA input current needed for the logical “1” level.

The internal resistance is 680 Ohm / 0,25 W. If now another input voltage is
needed, the totally required resistance can be calculated with the following
formula:

3

= (UE-1,3V)/I

R

ges

I
R

Example:

Is e.g. an input voltage of 24 V with a current of 10 mA wanted, you get from
the above formula Rges = 2270 Ohm. This means either the internal 680 Ohm
resistor has be replaced with a 2200 Ohm resistor (rounded to norm value), or
a resistor of 1590 Ohm has to be connected in series.

Attention:

When calculating the protective resistance the maximum dissipation of the
resistor has to be considered!

Power outputs

The power outputs of the ICOM-241 are extended outputs of the Tiny-Tiger®
Economy, which are equiped with a driver IC type TD62083 or compatible.
This IC has got eight open collector outputs.

The power outputs are lead to the 25-ch. Sub-D connector. The pin OVCC is
connected to a internal protector diode, so the outputs are secured against
overvoltage. This pin normally should have the same voltage potential as the
voltage to be switched.

ICOM-241

Serial interface

As a standard the ICOM-241 has two serial interfaces. From these the port
Ser0 can by choice be configured as RSR232 or RS485 interface. The port
Ser1 always is a RS232 interface. In PC mode this port is used for
downloading the program into the ICOM 241. In Run mode it can be used as a
usual RS232 interface.

Detailled information about the serial interfaces can be read after in the
BASIC-Tiger

®

„Device driver“ manual.

RS232

To configure port Ser0 as RS232 interface, the IC3 (MAX232) must be placed
into the appropriate socket and IC6 ( SN75176) has to removed from its
socket. After that the DIP switch at the left side of the chassis has to be
switched to RS232. It is recommended to place the IC 6 (SN75176) into the
dummy socket, so it’s always available when needed again.
