1. Introduction
This product is manufactured under strict quality control, and comes
with 5 years limited warranty. The warranty comes in effect from
the date of purchase. If there are any difficulties or questions during
the use, please contact our Technical Support Department. http://

2. Function
■
This is a serial communication interface converter which converts
RS232 signals to RS422 or RS485 signals and extends the
distance up to maximum 1.2km. It also allows to be connected to
maximum 10 devices by multi-drop mode as well as point to point
mode.
■
It is designed to operate without external power supply.
(When RS232 side is extended, use external power supply
shown in page 4, “6. Power Supply”.) However, there is a socket
for an adapter to supply power externally.
■
It includes highly-effective surge protector to protect itself
from the transient voltage(Max. 15KV) coming along the
communication line.
■
Especially, CS-428/9AT includes an automatic opening and
closing function for the output data so that the opening and closing
consent work in the multi-drop mode is automatically made by
the hardware, which makes you apply easily under any installing
environment without any software operation.

6. Power Supply
This unit operates by the power from TXD, RTS and DTR signal
generated from the computer or the RS232 port of the equipment when
no external power is supplied. When TXD, RTS and DTR signals
connected to the DE9 connector can not supply enough power, an
external power source is required. You can recognize whether the power
is being supplied or not, by cheking the power LED on the converter.
The power source part of the converter includes a high volume
condenser to supply stable power to the converter circuit by using TXD,
RTS and DTR signal. Therefore it may not work for a very short period
(within 0.1 second) until this condenser is filled with enough power.
Please wait for a second before starting to use converter after turning
on the TXD, RTS and DTR signal when TXD, RTS and DTR signal is
controlled directly in the application program.
The red LED light is turned on when power is supplied.
Supply an external power when power LED is off or dim.
7. Termination Resistor
When a communication error occurs due to high data rate or long cable
runs, enable the termination resistors to solve the problem.
■
Enabling Termination Resistor
* Termination resistor configuring are controlled by switches.
* Refer to '8. Operating Mode' to know how to set the switch.
8. Configuring Mode
This product allow user to select different operating modes to be
applied for various fields. Use the 4 dip switches on the bottom of
the product to set the desired operating modes before using.
■
Switch Configuration
After setting the switches, insert the line into the terminal block
and fix them with a screw driver. Connect the DE9 connector to
the RS232 port of the computer or serial device.
9. Configuration for RS422/485 4-wire
This connection is used for 1:1 (Point to Point) or 1:N (Multi-Drop)
full-duplex communication.(Max. 10 units)
■
Host and terminal configuring switch for the host and the terminal.
* When using RS422/485 4-wire interface, both point to
point and multi-drop mode are automatically supported.
* When using RS422 multi-drop mode, output signal line
does nothave to be opened and closed on the host side
since it is "dedicated" line. On the other hand for terminal
side, it always has to open and close the signal line when
it sends or receives communication data. This is done
automatically by hardware so the application program
does not have to control this.
