Conguration via DIP switch
Select the operating mode using the two DIP switches SW1 and SW2:
SW1 SW2 Communication mode
OFF OFF RS422 mode, RS485 4-wire mode
OFF ON
ON OFF RS485 2-wire mode (non-echo)
ON ON RS485 2-wire mode (echo)
If the RS422 or RS485 4-wire mode is selected, the DIP switches SW3 and SW4 are used
to activate/deactivate the terminating resistor (activate at the beginning and at the end of the
wiring):
SW3 Activate/deactivate the terminating resistor for 4-wire mode at the
receiver side
OFF Terminating resistor deactivated
ON Terminating resistor activated
SW4 Activate/deactivate the terminating resistor for 4-wire mode at the
transmitter side
OFF Terminating resistor deactivated
ON Terminating resistor activated
If the RS485 2-wire mode is selected, the DIP switch SW4 is used to activate/deactivate the
terminating resistor:
SW4 Activate/deactivate the terminating resistor for 2-wire mode at the
receiver and the transmitter side
OFF Terminating resistor deactivated
ON Terminating resistor activated
Transmission speed/cable length
The achievable baud rate may differ from the following tables depending on the
cable, ambient conditions, etc. The use of shielded cables is recommended for EIA-
422 and EIA-485 (CAT5, EIA/TIA/ANSI-568).
The tables were created using a CAT5e UTP cable at room temperature.

Using the terminals
The wire of the connection cable is pushed straight into a connection terminal (stripping the
cable about 6 - 7 mm).
In order to remove the wire from the terminal, press the corresponding white release button by
using for example a at screwdriver while pulling the wire out of the terminal simultaneously. Do
not use force when pulling out the wire or pressing the release button.

RS232 to RS422/RS485 Converter
Item no. 1693714
Intended use
This product is used for the connection of a device with RS422/RS485 interface to a RS232
port.
The voltage/power is supplied either via RS232 or via the two “PWR” terminals.
For safety and compliance reasons, the product must not be converted or modied in any way.
If you use the product for other purposes than those described above, the product may be dam-
aged. Moreover, improper use involves risks such as short-circuits, re, electric shocks, etc.
Please read the operating instructions carefully and do not discard them. Please include these
operating instructions when you pass the product on to a third party.

Voltage/power supply
a) Via RS232
The converter can be powered via RS232 (TXD, RTS, DTR connection) (follow information
on the RS232 interface you are using). Power LED “ ” on the converter lights up, if voltage/
power properly supplied.
If a number of RS422 / RS485 devices are connected to the converter, voltage/
power should be supplied via the terminals, see b).
b) Via terminals
6 terminals are located on the back of the converter. An external voltage/power supply is con-
nected via the two “PWR” terminals (5 - 9 V/DC, polarity irrelevant). Power LED “
” on the
converter lights up, if voltage/power properly supplied.
Connection
Congure the DIP switches rst.
Next do the wiring.
Connect the converter to your RS232 interface. If used, connect the extension cable 1: 1. The
knurled-head screws on the side of the converter are used to fasten the converter securely
to the RS232 port.
LED “
” lights up when voltage/power supply is correct.
LED “T” is lit or ashes during data transmission (T = “Transmitting”).
LED “R” is lit or ashes when data is received (R = “Receiving”).
Care and cleaning
Disconnect the product from the mains supply before each cleaning procedure.
Use a dry, lint-free cloth to clean the product.
Never use abrasive cleaning agents, rubbing alcohol or other chemical solutions, since these
could damage the casing or even impair operation.
Disposal
Electronic devices are recyclable materials and do not belong in the household
waste. Dispose of an unserviceable product in accordance with the relevant statu-
tory regulations. That way you full your statutory obligations and contribute to the
protection of the environment.
