RS232IO module
(Item No. #C01)
|
 RS232IO
is a general-purpose input and output module. It is connected to RS232 port
of a computer. It features 24 digital programmable input/output lines and 5
analogue input lines (2.5V fully range and 8 bit A/D resolution). The I/O
lines are organised into three 8-bit port, B, C and D. Each port can be
configured as input (all lines are input) or output (all lines are output).
The system uses 3 wires of RS232 port to communicate with host PC (TX, RX
and Ground). |
The system accepts various commands from the
host through its RS232 port:
These commands include:
(1) to configure 24 input and output lines and to read back the
configuration
(2) to output
data or to read data into the computer
(3) to read analogue voltages into
the host computer

Centronic 24-line programmable I/O card ---- CIO
(Item No. #C02)
|
 The
CIO-1 Centronic
24-line programmable I/O card is a general-purpose I/O card. It is connected
to a computer via a Centronic port. It offers 24 TTL input/output lines, organised into 4 groups: Port A, Port B,
upper four bits of Port C and lower four bits
of Port C. Each group can be configured as an input or output port. The 24 I/O lines are
available from a 26-way male DIL PCB header for easy connection. It requires
an 7-15V DC (1A) power supply. |
A DOS-based program "CIODos" and
a Windows95/98 program "CIOWin" are supplied with the I/O card. The programs
allow users to check functionality of the card. A Turbo Pascal 6 unit and
16-bit Windows Dynamic Link Libraries (DLLs) are also supplied with the
card. They contain basic I/O procedures. After declaring them in user’s
programs, users can call them anywhere in their TP6 or Windows’ programs.

RS232 16-line I/O card - SIO (Item No. #C03)
|
 This I/O card is
connected to a computer via a serial port (RS232 port). The card provides 8 output lines
and 8 input lines. Each line is TTL compatible. The 16 I/O lines are available from a
20-way male DIL PCB header for easy connection. The I/O card is connected to a PC via only
three wires of the RS232 port (namely TX, RX and Ground). The Baud rate is programmable
(1200, 2400, 4800 and 9600). There is no parity check bit. Data bit length is 8 and the
number of stop bit is 1. A byte transmitted from the host computer appears at the output
lines of the card. After each successful transmission, the card sends a byte, which
appears at the inputs, back to the computer. The card requires a 7-15V DC (1A) power
supply. An on-board 1A fuse is on the card.

A DOS-based program
"SIODos" and a Windows95/98 program "SIOWin" are supplied with the I/O
card. They allow users to check functionality of the card. A Turbo Pascal 6 unit is
supplied with the card, which contains basic I/O functions for controlling the I/O card.
After declaring the unit in a TP6 programs, users can call the functions anywhere in the
TP6 programs. The "SIOWin" is written in Visual Basic 5. Since VB5 has a serial
port control "MSCOMM", you can use this to control the I/O card directly without
using any external DLLs.
