Advantech BB-232MSS2

The RS-232 Four Port Mini Smart Switch/Port Combiner, Model 232MSS2, allows one RS-232 host device to connect to as many as four RS-232 devices. The 232MSS2 can function as a software and/or hardware controlled switch. As a software controlled switch, referred to as smart switch mode, the device connected to the master port of the 232MSS2 has control over which one of the four ports it is connected to. As a hardware controlled switch, referred to as port combiner mode, the handshake lines of the devices connected to the four ports are used to gain access to the master port.

The 232MSS2 has an enhanced mode, which offers special timer features. The timer features can be used to prevent slave devices from receiving preamble commands, inadvertent switching from binary/graphic file transfers, and inactive slave devices from holding control of the master port. The timer has two different modes: an inactivity mode and an inadvertent switch mode. When in inactivity mode, the 232MSS2 will monitor the data lines. If there is no activity for the specified time, the selected slave port will be disconnected from the master port. When in inadvertent switch mode, the 232MSS2 will ignore switching commands for the specified time. After this time has expired, the selected slave port will be disconnected from the master port.
