I-7514U CR - 4-port active RS-485 HUB

Industrial Isolated 4-Channel Active RS-485 Hub. Model I-7514U by ICP-DAS. 

RS-485 Active Hub

The I-7514U is an active RS-485 hub with 4 output channels and one input channel. Each output channel is equipped with an individual driver, ensuring independent operation. Data sent to the input channel is simultaneously forwarded to all four output channels. This allows the same information to be distributed simultaneously to multiple devices connected to the outputs. This solution makes the RS-485 network more flexible and efficient, enabling better data transmission management in industrial systems.

Splitter

Data from the master input is transmitted to all four RS-485 slave channels, allowing information to be distributed simultaneously to multiple devices connected to these channels. However, data from the slave channels is only sent back to the master input, meaning communication is unidirectional from the slave channels to the master. This design reduces the risk of interference between individual slave channels since each slave channel operates independently and does not affect the others. As a result, RS-485 networks become more resistant to interference and more reliable, which is crucial in industrial applications where stability and continuous communication are essential.

Baud Rate Configuration

The I-7514U offers two baud rate configuration modes: the Self-Tuner mode and the Fixed Baud Rate mode. The Self-Tuner mode supports various baud rates and data formats, operating similarly to the I-7513 and I-7510 models. The Fixed Baud Rate mode ensures better data transmission quality over long, degraded lines or in environments with electrical interference.

RS-485 Short Circuit Protection

The short circuit protection feature can automatically disable a faulty channel, protecting the communication system. If a connected RS-485 device fails, the faulty channel will be isolated to ensure the normal operation of the remaining devices.

Termination Resistors

In certain critical environments, termination resistors may be necessary to prevent serial signal reflections. The I-7514U includes a selectable 120-ohm termination resistor for each channel, adjustable via a jumper (disabled by default).

LED Indicators

The I-7514U has 6 LED indicators signaling power status and network traffic. The TxD/RxD LED will blink when the device is transmitting or receiving data.
