RS-232 two pairs of an intelligent sharing 
 First, use 
 RS232 two pairs of an intelligence-sharing (Model: HUB2232Z) for two RS232 host computer to control a RS232 next bit machine communication connection. HUB2232Z the traditional RS232 port to achieve the two pairs of more than one machine communication. HUB2232Z have two host computer socket (DB9 pin holder) and a lower machine socket (DB9 female head), without modifying the software, no power supply. HUB2232Z the RS232 serial port TXD (send), RXD (receive) and GND (signal ground) signal. HUB2232Z for two PC's RS232 port and RS232 port to drive an audience-bit machine. 

 Second, the installation and performance 
 The appearance HUB2232Z DB25 (pin) / DB9 (hole) size of the adapter box and to DB9 hole can be plugged directly into 
 On the PC DB9 pin RS232 serial port. HUB2232Z no external power supply! HUB2232Z also supporting with two DB9 pin holder braids, can directly to plug HUB2232Z DB25 end. 
 Boston HUB2232Z intelligent RS-232 hubs can identify two host computer RS-232 to send the order, to avoid at the same time send a result of system failures. In other words, even if the two host computer are sent simultaneously, HUB2232Z will select the host computer to send the start time leading right to send data until a host computer to send data after a host computer before they can begin sending data. HUB2232Z with two-way communications capabilities, the current bit machine to send the two host computer receives the same data does not distinguish between the address. 
 Buy three or more HUB2232Z can receive a Windows 95/NT environment of VB, the C + +, DELPHI 
 Language RS232 serial port communications development software (a 3-inch CD-ROM).
