• Host
10. Configuration for RS485 4-wire
This connection is used for N:N half-duplex communication.(Max.
10 units)
■
Terminal Switch Configuration
* 4-wire RS485 is a bus connection. There is no classification
of host or terminal; all devices are considered terminal, so
output signal lines must be opened and closed when data
is sent or received. This is done automatically by hardware
so the application program does not have to control this.

11. Configuration for RS485 2-wire
This connection is used for N:N half-duplex communication.(Max.
10 units)
■
Terminal Switch Configuration
* 2-wire RS485 is a bus connection. There is no classification
of host or terminal; all devices are considered terminal, so

Non-Echo/Echo Setting (Set when using 2-wire RS485)

Echo
〉
Echo : Select 2-wire RS485 echo mode. Data from
RS232 TXD is sent to another device through
RS485 TRX+/TRX-and at the same time
received back through RS232 RXD like an echo.
So data sent through TXD can be checked with
data received by RXD.
Non Echo : Select 2-wire RS485 non-echo mode. Data sent
through TXD is sent to another device but is not
received by RXD. Data sent cannot be checked.
13. Termination Resistor Configuration
■
Setting RS422 or 4-wire RS485 Termination Resistor
* Set 2-wire RS485 termination resistor as well when using long
line or high speed.

Self-test (Loopback Test)
1) Set to RS422 mode.
2) Connect CS-428/9AT mini2 to RS232 port and wire
them as show below.
3) Download a test program, TestView from our technical
support website at http://www.solvline.com
4) Install test program.
If you need more information about TestView, please refer
TestView manual.
5) Open the serial port(RS232) in TestView and click, send
data "button".
6) If you see similar screen as below, your converter has no
problem.
■
You can perform loopback in RS422 mode
