Some benefits of the Control-it 5100 RS485
Co - Processor:
Saves Time:
- Allows Standard screwdriver connection to your wiring - no
soldering or crimping needed
- No communication protocols to handle. All remote units are
mapped into memory.
- Automatically finds boards connected to the network and identifies
whether they are a Control-it 5020, 5030, or a 5040.
High Performance:
- Can scan 4 Control-it 5020 or 5040 units per millisecond.
- Can scan 2 Control-it 5030 units per millisecond.
- Compact binary protocol used.
Versatile:
- Small size, lightweight unit
- 9 - 24 volt power supply
- Works with any terminal software
Easy to Install:
- Rear panel lights show transmit and receive lines.
- The first 6 boards each have a status light.
Safe:
- Fully floating circuitry protects your computer from power
spikes
Built -in Reliability:
- Designed to exceed international standards for noise immunity
- Complete isolation of all comms and I/O sections minimises
outside interference errors
- 9 LEDs and a comprehensive trouble-shooting guide for easy
diagnosis of suspected system faults

What makes the Control-it 5100 so good?
When there are relay and input boards to control on a remote serial
line the normal method is to use the COM1 or COM2 serial port. These ports
are limited in comms speed to a maximum of 115Kbaud. If you are working
under Windows then the limit may be as low as 19.2kbaud.
To communicate with a remote board a message is built up and sent out
the serial port. The response is received and has to be analysed. If there
has been a communication error (determined by a checksum or CRC) then
a second and perhaps third attempt must be made. If there is no response
from a board address then the routines must timeout and report an error.
All this can be avoided by letting the Control-it 5100 do the job. It
has an on board computer to handle all the communications and re-tries,
and can do all this at 690kbytes/second. Because of its compact binary
protocol, performance is 10 times greater than the equivalent system running
an ASCII based protocol at 115kbaud. The board does not need a free comms
channel, does not tie up any interrupt lines, and does not require DMA
(Direct Memory Access).
The Control-it 5100 is a win-win situation. Your PC does not
have to labour away getting data from remote boards, and the Control-it
5100 does it 10 times faster.
And it's so easy to switch or read remote inputs and outputs. If the
Control-it 5100 board is at I/O address 280 hex, and the remote
module (such as Control-it 5020) is set to address 0, then to turn
on relay 0 write a 1 to 280 hex. To turn on relay 1, write a 2 and so
on. To read inputs assume that there is a remote input board (such as
Control-it 5030) set to address 1. Inputs 0 to 7 will automatically
appear at address 282 hex in your computer.
