For Loading and Operation of HCS02 you need a IBM-PC compatible Computer running at least Windows 95 OSR2.
Further supported configuration is Windows 2000 SP1
From the HCS02-Compact-Disc Media, the KEA!-420 terminal emulation software has
to be installed. The usual location for installing KEA! will be
C:\PROGRAMM\KEA\
The contents of the Directory KEA-MBSCOM2 must be copied to the USER
subdirectory of the directory where KEA! is installed
Copy the contents of the directory HCS02 on the
HCS02-Compact-Disc-Media
to the directory C:\projects\HCS02\ on the PC.

How to load and operate HCS02 Software
If a validly built HCS02-Firware-EPROM is installed, the Software in this EPROM starts automatically.
However, as long there is no EPROM, HCS02 boots up as any default MCS-BASIC-52 computer in direct command mode.
To interact with the BASIC-Interpreter, a terminal needs to be connected to HCS02's serial port. The Terminal should be set to 19200 bit/sec, 8 bit, no parity.
After connecting power or in uncertainty, press the RESET button and hit the SPACE-bar on the terminal. This should allow HCS02 to auto-baudrate-detect the speed of the terminal.
Upon successful detection of the terminal speed, HCS02 should print a message similar to this one:
*MCS-51(tm) BASIC V1.1* READY > |
Repeat pressing SPACE until the message appears.
If the message does not appear when pressing SPACE, try resetting HCS02 by pushing the RESET-Button again.

C:\projects\HCS02\hcs02r03.hex
There are 64 possible timeouts in HCS02. They are numbered from 0 thru 63.
Timeouts are divided amongst 4 classes. Classes are distinguished by the granularity in which timeouts are running. This granularity is measured by the time a "tick" lasts. Timeouts can be started by specifying the number of "ticks" until expiry of the timeout.
| Timeout Class number | Timeout number range | time for one tick |
| 0 | 0..15 | 100 milliseconds |
| 1 | 16..31 | 1 second |
| 2 | 32..47 | 10 seconds |
| 3 | 48..63 | 100 seconds |
Controlling PULSER in sequence steps
%SEQ_PULS(<pulser_command>,<pulser_parameter>)
| Symbolic command | numeric value | Description | Meaning of Parameter |
| pev_bron | 1 | turn BI-relay on | number of BI-relay |
| pev_broff | 2 | turn BI-relay off | number of BI-relay |
| pev_brtog | 3 | toggle state of BI-relay | number of BI-relay |
| pev_mron | 4 | turn MO-relay on | number of MO-relay |
| pev_mroff | 5 | turn MO-relay off | number of MO-relay |
| pev_mrtog | 6 | toggle state of MO-relay | number of MO-relay |
| pev_mbon | 7 | memorize BI-relay as ON | number of BI-relay |
| pev_mboff | 8 | memorize BI-relay as OFF | number of BI-relay |
| pev_mmon | 9 | memorize MO-relay as ON | number of MO-relay |
| pev_mmoff | 10 | memorize MO-relay as OFF | number of MO-relay |
The HCS02 sequencer provides steps for starting
and stopping timeouts.
Starting timeouts in sequences
A sequence step starting a timeout looks like:
%SEQ_TOSTART(<slot_number>,<tick_count>)
A sequence step stopping a timeout looks like:
%SEQ_TOSTOP(<slot_number>)
