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
• Configure the DIP switches first.
• 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 flashes during data transmission (T = "Transmitting").
• LED "R" is lit or flashes 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 fulfil your statutory obligations and contribute to the
protection of the environment.
