Multidrop link
|
32 station RS485 multi-drop link via 5 or 6 wire
connections. |
Easy connection to computer's serial
|
Inexpensive RS232/RS485 converter allows for
easy connection to the computer's serial port. (Available as
a separate item.) |
Reach of link
|
Link can be up to 4000' or 1200m long. For longer
distances, a digital repeater can be used. |
Station independence
|
Each station is optically isolated to 2500 volts. |
Three powering modes supported
|
Two individual power supplies to each station.
Full optoisolation. |
One external power supply per station via the
computer link. Full optoisolation. |
Power provided via the computer link only. |
Broadcasting capability
|
Triple mode broadcasting capability. |
Optoisolation circuit voltage
|
2500 volts optoisolation circuit. |
Assistance
|
On-line Help command. |
Available lines
|
32 TTL compatible lines per station (42 if there
is only one station in the network) independently configurable
as inputs or outputs. |
Ease of connection to lines
|
Phone jacks (RJ11/12) and terminal strip pads
on board for easy hook up to a variety of link wire sizes. |
Line protection
|
All power lines are reverse polarity protected
by diodes in series. |
PWM
|
Two independent 10-10,000 Hz, 0-100% duty cycle
Pulse Width Modulation channels. |
Interrupt lines
|
High and Low interrupt lines (edge sensitive)
available when the station is active. |
Baud rate
|
Baud rate configurable, via software, from 300
baud up to 115200 baud. |
Resistance, conductance & capacitance reading
|
Eight channels for reading relative resistance,
fluid conductance or capacitance. |
Stepper motors
|
Four stepper motor ports with all the necessary
logic embedded to facilitate monophasic, biphasic and half-step
modes. |
Repeat ease
|
Single "Again" command allows repeat of previous
command at a fast rate. |
Easy access to active configuration
|
A configurable status feature which sends the
active configuration of any parallel port, stepper motor port,
or the PWM back to the terminal. |
Analog-to-digital channels
|
Eleven channel analog-to-digital converter with
either 8, 10 or 12 bit resolution is available. |
Hardware & software
|
Associated hardware and software development
is easy and cost effective. |
Ease of access to functions
|
All functions can be called by means of simple
ASCII commands. |
Low cost per station due to
|
Intrinsic low cost of the units. |
No need for "on-board" programming thus allowing for very low costs associated with software development. |
The set of functions embedded in the ITC232-A IC drastically reduces associated hardware. As an example, an excellent precision liquid level measurement system based on conductivity can be implemented with the addition of only two 4066 IC's, an inverter (4069 )or transistor and a capacitor. The use of the ITC232-A also brings in the well known simplicity advantage this chip offers. |
