-->> RS232 to RS485 <<--
Currently available in the market RS232 to RS232 to
RS485 device, commonly known as RS485 converters are many brands and models,
priced from a few hundred dollars to tens of dollars or even thousand
dollars, of course, there is greater performance and reliability of the
difference. There are a number of common issues to consider:
1, can supply their own
2, load capacity
3, whether the protocol conversion chip
4, able to multi-output
If the product can not meet the requirements, our company can provide
the following solutions:
I HOST6 designed a multi-plate, the first dual-control
system for closed-loop control of the main equipment, the realization
of the function of a very large number of details, please refer to the
relevant page of the RS232 to RS485 products is more than natural, but
to achieve this types of conversion has the following characteristics:
1, using the structure of PCI card can be built into the chassis, the
system of higher integration, especially suitable for a number of self-contained
special equipment;
2, for some non-PC applications, do not use PCI slot, ATX power supply
can also 4PIN the access of small terminal or another terminal 3PINHead
power, power of strong and effective guarantee of the reliability of data
transmission and long transmission distance ;
3, more than the structure of multiple land can support two-way 4-way
full-duplex RS485 transceivers, on the one hand, the general standard
of RS485 chip load is only 32 points, more large-scale multi-channel system
will need to bring together, HOST6 itself provides 4-way expansion of
the use of standard chip can support 32 * 4 = 128 points, the use of 1
/ 2 load the chip can support 64 * 4 = 256 points, the use of 1 / 4 load
of chips can support 128 * 4 = 512 points and is a two-way; On the other
hand, many works in practice, it is difficult to strictly in accordance
with the provisions of RS485 points from start to finish all the series
together, but often a number of branches formed naturally (for example,
a building housing a branch of) , so that multi-channel transceiver is
to meet this requirement;
4, In addition, HOST6 can also provide a buffer zone of the encryption
algorithm can be designed according to customer's data flow structure,
so that the flow of data bus is not illegal analysis and theft, but also
enhanced the reliability of the system. |
