DS485TM Frequently Asked Questions (FAQ)
-
The maximum cable length for DS485TM is dependent on the baud rate and cable characteristics. As a general guideline, TI recommends a maximum cable length of 4000 feet (1219 meters) at 9600 bps, 2000 feet (610 meters) at 19,200 bps, and 1000 feet (305 meters) at 38,400 bps.
-
The DS485TM bus should be terminated with a 120-ohm resistor at each end of the bus to prevent signal reflections and ensure reliable data transmission.
-
The maximum number of nodes that can be connected to a DS485TM bus is 32, assuming each node has a unit load (UL) of 1. A UL is a measure of the bus loading, with 1 UL being equivalent to 12 mA of current.
-
Yes, the DS485TM can be used in a multi-drop configuration, where multiple devices are connected to the same bus. However, the total bus loading should not exceed 32 unit loads (UL) to ensure reliable data transmission.
-
Error handling and retries should be implemented at the application layer. The DS485TM provides a receive error flag (RE) that can be used to detect errors. The application should implement a retry mechanism to retransmit data in case of errors.
