RS232 Splitter, DTECH 4 Port Serial Expansion Box 1x4 COM Port Expander with Power Adapter for Sharing PCs and Capture Data

4 way serial port divider is a cost effective solution when you need to manage and control multiple DB9 RS232 devices (monitor, printer, modem, scales, scanner) via computer.

Connection 1: Monitor and Control Multiple Terminal Device via 1 PC

1 PC connected to input port, and 4 devices to output ports via Straight Through serial cable separately (functioned as RS232 divider: 1 master controls 4 slave).

Serial port combiner splits 1 port in multi hardware COM ports that are used by several applications, so the applications can receive the same data from PC at once (duplicator).

Connection 2: Capture Data from 1 Terminal Device on Redundant PCs

4 PCs connected to output port, 1 data acquisition equipment to input port via Null Modem serial cable separately. (functioned as RS-232 switch: 4 masters control 1 slave)

Several PCs receive data from 1 device, sharing multiple PCs on a single peripheral; only 1 terminal device can send data to a laptop at a time.

RS232 hub splitter auto-outputs the values as long as its wired and powered. DC 5V 1A power adapter provides stable power to transmit and receive data without any delay; ±8kV ESD electrostatic discharge protection:
