Important Safety Instructions

The symbol with the exclamation mark in the triangle indicates important information in this operating manual. Always read this information carefully.

Installation/Mounting

The circuit board of the converter can be soldered in directly or via a socket strip. It is also possible to solder on a 9-pole SubD plug (e.g. Conrad order no. 742066) and attach a USB cable to the other end of the circuit board (+5V=, Data+, Data-, GND).
If you do not solder on a 9-pole SubD plug, it is possible to break off the corresponding part of the circuit board at a predetermined breaking point to save space on the own
application.

Software Installation

1. Install the supplied driver software first!
2. Only then may the converter be connected to the USB port.

Disposal

This product must be disposed of in accordance with local regulations.

Description of symbols

The following symbols are on the product/appliance or are used in the text:
The symbol with the exclamation mark in the triangle is used to indicate important information in these operating instructions. Always read this information carefully.

Safety instructions

Read the operating instructions carefully and especially observe the safety information. If you do not follow the safety instructions and information on proper handling in this manual, we assume no liability for any resulting personal injury or damage to property. Such cases will invalidate the warranty/guarantee.

• For safety reasons, any unauthorized conversion and/or modification to the product are not permitted.
• The product is not a toy and must be kept out of the reach of children.
• The product must not get damp or wet.
• Do not leave packaging material laying around carelessly. These may become dangerous playing mate-rial for children.

Pin assignment/name

• USB_Vcc = supply voltage via USB, +5V=
• Data- = Data line for USB
• Data+ = Data line for USB

Note

• Pins 1 to 8 carry RS232-conform levels
• Pin 10 is the mutual ground (GND)
• Supply voltage +5V from USB port (max. 100mA!)
• Pin 9 must be used for microcontrollers requiring a %v level on the RX input.
• Pin 15 to pin 20 are I/Os, the RXD detects voltages from 3.3V to 5V, TXD emits a level of 3.3V. If controllers with 5V are applied, you have to use the connection TXD_5V.
• If the RS232-conform level is required on pins 1 to 8, you have to make a connection between pin 14 (SUSPEND_3V) and pin 13 (ENABLE).
• Via pin 12/14 (SUSPEND_3V/SUSPEND_5V), you can tell the external hardware (e.g. microcontroller) whether a USB connection was established. These pins are on high level when the USB connection is detected!

Installation /assembly

• The converter can be equipped with a SubD plug and a 4-pole USB connection cable (+5V=, Data+, Data-, GND) as well as plugged into a corresponding socket on another circuit board via pin strips.
  When soldering on the 9-pole SubD plug, check the right alignment of the plug on the circuit board (4 resp. 5 contact strips on the circuit board and on the socket).
  When connecting a USB connection cable, make sure that the cable connections are established cor-rectly. In case of wrong polarity, not only the converter is destroyed but also the corresponding USB port. Loss of warranty/guarantee!

• If you do not need the small circuit board part for the 9-pole SubD plug, carefully snap it off at the predetermined breaking point.

• Solder in the enclosed pin strips for installation in a plug-type socket. Make sure that the soldering pro-cess is as short as possible to prevent overheating of the circuit board and the other elements. Observe all usual safety instructions when soldering.
  The pin strips must be soldered on at the bottom of the circuit board so that the elements are located on the other (top) side.

Software installation

1. First install the enclosed driver software!
2. Then connect the converter with the USB port.

Disposal

This symbol must appear on any electrical and electronic equipment placed on the EU market. This symbol indicates that this device should not be disposed of as unsorted municipal waste at the end of its service life.
Owners of WEEE (Waste from Electrical and Electronic Equipment) shall dispose of it separate-ly from unsorted municipal waste. Spent batteries and accumulators, which are not enclosed by the WEEE, as well as lamps that can be removed from the WEEE in a non-destructive manner, must be removed by end users from the WEEE in a non-destructive manner before it is handed over to a collection point.

Distributors of electrical and electronic equipment are legally obliged to provide free take-back of waste. Conrad provides the following return options free of charge (more details on our website):

• in our Conrad offices
• at the Conrad collection points
• at the collection points of public waste management authorities or the collection points set up by manu-facturers or distributors within the meaning of the ElektroG
  End users are responsible for deleting personal data from the WEEE to be disposed of.
  It should be noted that different obligations about the return or recycling of WEEE may apply in countries outside of Germany.
