15. - iPECS-MG System support 3 kinds of connection methods from PC to MPB for monitoring system 1. Serial Connection 2. Modem Connection 3. TCP/IP Connection - In case of TCP/IP Connection, max 5 Port can be connected at the same time. - TCP/IP Connection default TCP port number is 5003. ex) 10.10.10.1:5003 - iPECS-MG System support to connection from PC to each internal IPP boards through MPB IP. - Internal board IP Connection default TCP port number start from 5102~5118. - TCP Port is decided by slot number. Ex)VOIB is inserted slot 2 then TCP port is 5102 > 10.10.10.1:5102 Serial Connection TCP/IP Connection 10.10.10.1:5003 TCP/IP Connection for Internal Boards Slot02: 10.10.10.1:5102 Slot03: 10.10.10.1:5103 : Slot17: 10.10.10.1:5117 Slot18: 10.10.10.1:5118 Connection Type Overview Trace & Maintenance

17. 1 Serial Connection Be sure PC application port is not assigned to serial port that you want to connect. For trace, program print port to the proper serial port(PGM 231 - BTN 6). Connect using hyper terminal or other terminal program. 2 LAN Connection Be sure PC application port is not assigned to telnet. Program IP address of the system(PGM 108 – BTN 1, BTN 3). Reset the system with DIP Switch 1 at ON position. For trace, program print port to telnet(PGM 231 – BTN 6). Connect via telnet. 3 Modem Connection Be sure PC application port is not assigned to MODU. For trace, program print port to MODU(PGM 231 – BTN 6). Connect via modem.
