What is the different application for interface TCP/IP, RS-232/422/485 for Pongee Access Controller?
(a). TCP/IP : No distance limitation between the Access Controller and PC (running Pegasus PGAccess), anywhere there is RJ-45 interface of Ethernet HUB or Router in the worldwide, connects to numerous Pongee Access Controllers at the same time. (b). RS- 232 : Distance limitation is 15 meters between the Access Controller and PC, connects up to 7~8 sets Pongee Access Controllers at the same time. (c). RS- 422 : Full-duplex communication, distance limitation is 1,200 meters between the Access Controller and PC, connects up to 160 sets Access Controllers thru Pongee Multi-channel converter PCP832-16 at the same time. (d). RS- 485 : Half-duplex communication, distance limitation is 1,200 meters between the Access Controller and PC, connects up to 32 sets Access Controllers thru Pongee RS485/232 Converter at the same time.
