 2-way RS-232 RS-485/232 shared 1 

 First, use 

 2-way RS-232 connection 1 RS-485/232 intelligence-sharing (Model: HUB2215Z) for the two RS-232 host computer common control an RS-485 or RS-232 machine communication. HUB2215Z make traditional RS-232 port and two pairs of more than one machine communication. HUB2215Z has two upper drive connector (DB-9 pin holder and the DB-9 socket) and a lower machine outlet (DB-9 needle, with terminals), without modifying the software, 5V supply. HUB2215Z the RS-232 serial port, only TXD (transmit), RXD (receive) and GND (signal ground) three signals. 

 HUB2215Z two host computer DB-9 pin and a bit under the machine DB-9 pin can be directly extrapolated Boshi electronic various converter constitute RS-232/485/422 share. Then HUB2215Z RS-232/485/422 port on the two PC's to drive the machine of an audience RS-232/485/422 port. 

 Second, the installation and performance 

 HUB2215Z appearance for the DB-25 (pin) / DB-9 (pin) adapter box the size of the DB-9 pin RS-232 pin assignments with the PC DB-9 pin holder and RS-232. HUB2215Z requires an external 5V power supply. HUB2215Z supporting with two DB-9 needles and two DB-9 wiring board of the hole head (pictured), directly into HUB2215Z DB-25 end. 

 Boston HUB2215Z 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, HUB2215Z 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. HUB2215Z 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. 

 DB-9 pin and a bit under the machine DB-9 pin HUB2215Z two host computer can be directly extrapolated Boshi electronic converters of all kinds RS-232/RS-485/422 constitute a common RS-232/RS-485 / RS-422 intelligence-sharing.
