Product Description
The MHUBX8 is an 8-port automatic RS485 repeater Hub (non-isolated) with a Master RS232/RS485 Port.The unit can be used to expand RS485 serial communications networks by increasing the maximum distance and/or number of nodes. The unit features an automatic transmit enable circuit with fast turn-around time(25uSec) to receive data from target devices without the need to add delays to your software. Data received by the master port is transmitted to all eight distribution ports (CHA thru CHH). Data received into a distribution port is transmitted out the master port, but is NOT transmitted out any other distribution ports. Each distribution port has its own termination jumper and an RXEN (receive enable) jumper. Bias is fixed with 620 Ohms of pull-up and pull-down resistance to hold the data lines in a known state when the data lines are inactive. The Master Port has jumper selectable bias and termination jumpers. Each distribution bidirectional port on the MHUBX8 hub will support up to 32 full-load RS485 devices. Need something special?
