描述 Description

Model BB-232MSS2, RS-232 4-Port Mini-Smart Switch/Port Combiner, allows one RS-232 host device to connect to up to four RS-232 devices. Model BB-232MSS2 can function as a software and/or hardware controlled switch. There are four LEDs that indicate which port is connected to the master port. The master port can be configured as a DTE or DCE port by an internal switch setting (see datasheet). If the master port is configured as a DTE port, the four slave ports automatically become DCE ports. Handshake lines DSR and DTR are connected together and are not passed through to the master port. There is no delay through the device and data is not buffered. The communication format is set via dipswitch 1 (SW1 - see datasheet).NOTE: The data format and rates mentioned are used to switch Model BB-232MSS2. Communication between the devices can use any format or data rate.NOTE: Power supply required, not included, sold separately.
