Troubleshooting

RS485 Communication

TESCOM™ Model # 82948 USB to RS485 Converter

Locate the four DIP switches on the back of the converter. The 
switches should be configured as follows:

• 

RS485

• 

Echo OFF

• 

2 Wire

• 

2 Wire

Third Party RS232 to RS485 Converters 

RS232 to RS485 converters range in modes of operation. If your 
application requires an RS232 to RS485 converter, it must be 
configured as follows: 

• 

Echo off. 

• 

Transmitted data, SD, is used for flow control. 

• 

No handshake control (RTS/CTS, DSR/DTR)

Additionally, for 4-wire RS422 converters (half duplex):

• 

Connect: +TD to +RD

• 

Connect: –TD to –RD

Acceptable Resistance Values 

The resistance values must be measured with all external wiring 
disconnected, including the power. Ensure converter screw 
terminals are tight. 
Resistance levels outside the acceptable ranges may indicate 
damaged RS485 components on the ER5000. Contact your 
TESCOM representative.

ER5000 RS485 Interface 

• 

+RS485 to GND = 10KΩ to 50KΩ 

• 

–RS485 to GND = 10KΩ to 50KΩ 

Converter RS485 Interface 

• 

+RS485 to GND = 3KΩ to 5KΩ 

• 

–RS485 to GND = 900Ω to 1.2KΩ
