CS- 428 RS232 to RS485
Converter |
|
CS-428 converts RS232 signals to RS422 or 485. It is an
efficient solution for applying adva ntages
of RS422/485 to legacy RS232 devices. The converter
operates with no extra software installation. With
simple DIP switch toggling, RS422 or RS485 can be
selected. Also, the product is fully compatible with
serial COM port in PC.

Auto RTS Control (Auto Toggling)
|
 |
|
|
|
Under 1:N communication environment, it is undesirable
that multiple devices send data at once, causing
electrical collision that leads to an error. In order
to prevent this, only one device needs to send data at
a time, which means that data I/O control is necessary
at certain points. CS-428/9AT performs automatic
toggling by hardware, saving extra programming work. |

What
is RS485 Echo Mode?
The point which is different
from the method for RS485 Non-echo mode is that the
output signal line by itself is input again to the input
signal line. Therefore, it is possible to confirm whether
the data sent crashes with the data sent by an other
terminal or not by reading the echoed data.
This operating mode is scarcely used except
in some special purposes.
RTS control & Auto Toggling CS-428/9
: The RTS signal line must be kept as “ON” only
when a signal is sent from the application program at
terminal side, but must be kept as “OFF” otherwise.
CS-428/9AT : All operation is controlled
by hardware circuit so no operation is required by application
program.
