Cascading Multiple Switches
If you have more than four devices that are sending data, more
than one 232BSS4 can be cascaded, allowing more ports to be
added. The 232BSS4 buffers data from all ports at once, making it
well suited for devices that will send a fixed amount of data at
sporadic intervals, such as measurement instruments, security
access card readers, barcode scanners, or time clocks. Below is an
explanation of how best to utilize the 232BSS4 to connect these
devices to your PC.
