Serial Converter

Converter

Function of equipment doubles when connected to other equipment, devices, computers and so on. Therefore, communication of equipment is an important factor of both users at industrial sites and end users. In order for the incoming and outgoing data to be transmitted without any problems, each device participating in the communication must be able to recognize the data sent by each other.

However, the communication is often impossible because different equipment uses different communication specifications and protocols. This is similar to what happens when two people who use different words. An interpreter that translates them between different words is required. Likewise, the communication of equipment requires something that transforms between different communication specifications and protocols: converter.

The converter allows both sides to communicate without any variation in existing communication specifications and protocols. Because there are so many different types of communication specifications and protocols, there are also many different types of converters.

Serial

RS232 is the most simple and common equipment communication standard established by the EIA(Electronic Industries Association). As it only supports 1:1 communication and is mainly used for communication within 100m(vary on the speed of communication), it has been used in many industrial sites up to now due to its simplicity and affordability.

RS422 and RS485 are complementary standards to RS232 shortcomings. As compared to RS232 with only 1:1 communication and limited to short distance communication, RS422 and RS485 uses four or two signal lines, supporting long distance communication up to 1.2km with a stronger response to noise. RS422/485 also supports multi-drop mode, enabling communication in a more complex and wider environment.

BASSO-1010DS

Product

LED

Power (Red): Illuminates at BASSO-1010DS power input (when Power LED switch is ON)

Connector

Serial Port(RS232, RS422/RS485): The serial port that can communicate. (Please refer to APPENDIX for pin specifications)

Function

BASSO-1010DS converts RS232 signal to RS422 or RS485 signal and performs the following functions:

Converts RS232 to RS422/485

Converts short distance communication RS232 to long distance communication RS422/RS485.

Port Powered

This product is designed to operate without external power supply when connected to RS232 connector(DB9) on a PC or any serial device(additional power connection is required when using RS232 for extended use). However, the external power input terminals are also ready for use in environments which require extra power.

[Tip]

This product uses the RTS, DTR signals that are output from the RS232 port of a PC or device as power source when power is not supplied externally(if the cable length is extended or RS232 power specification is insufficient, it is recommended to use external power).

The Power LED on the converter shows if the power is ON. The power supply part embeds a high capacity condenser to supply stable power to the converter circuit using RTS and DTR signals. This condenser may not operate for a shot time(within 0.1 seconds) until it is fully energized. The LED lights up when power is applied to the converter. If the LED does not illuminate or the color of the LED is not clear, blinks or changes in brightness periodically, please use an external power source.

Terminating Resistance

The built-in terminating resistance allows users to set the terminating resistance(120Ω) to solve the problem if noise on track causes a communication failure. (Please refer to 6. Settings for terminating resistance setting method)

Connection

Device – Device#1 Connection(RS422/485)

The device-to-device connection is performed by converting RS232 to RS422/485.

Wiring1. Device – Device#1 (RS422)

Wiring2. Device – Device#1 (RS485)

The RS232 port is as DCE(Data Communication Equipment) mode, connected to the DTE port such as a PC in direct connection.

Device – Device#2 Connection(RS422/485)

Connecting BASSO-1010DS to both sides of two RS232-communicating devices enables RS232 long distance communication.

Wiring1. Device – Device#2 (RS422)

Device – Device#3 Connection(RS422/RS485 Multi-Drop)

Wiring1. Device – Device#3 (RS422)

Wiring2. Device – Device#3 (RS485)

Settings

Set the setting switch on bottom of BASSO-1010DS to the desired mode.
