I/O Cable Data Sheets C GFK-0898F Appendix C – I/O Cable Data Sheets C-5 Expansion Port Pin Assignments The following table lists the expansion port pin assignments you will need when building remote cables. All connections between cables are point-to point, that is, pin 2 of one end to pin 2 of the opposite end, pin 3 to pin 3, etc. Table B-1. Expansion Port Pin Assignments Pin Number Sigl me Function 16 DIODT I/O Serial Data Positive 17 DIODT/ I/O Serial Data Negative 24 DIOCLK I/O Serial Clock Positive 25 DIOCLK/ I/O Serial Clock Negative 20 DRSEL Remote Select Positive 21 DRSEL/ Remote Select Negative 12 DRPERR Parity Error Positive 13 DRPERR/ Parity Error Negative 8 DRMRUN Remote Run Positive 9 DRMRUN/ Remote Run Negative 2 DFRAME Cycle Frame Positive 3 DFRAME/ Cycle Frame Negative 1 FGND Frame Ground for Cable Shield 7 0V Logic Ground I/O Expansion Bus Termition When two or more baseplates are cabled together in an expansion system, the I/O expansion bus must be properly termited. The I/O bus must be termited at the last baseplate in an expansion system. Each sigl is termited with 120 ohm, 1/4 watt resistors d between the appropriate pins, as follows (see the above table, also): pins 16 - 17; 24 - 25; 20 - 21; 12 - 13; 8 - 9; 2 - 3 The I/O bus termition can be done one of the following ways: By installing an I/O Bus Termitor Plug, catalog number IC693ACC307, on the last expansion baseplate (local expansion baseplate or remote baseplate) in the system. The Termitor Plug has a resistor pack physically mounted inside of a connector. The I/O Bus Termitor Plug is shipped with each baseplate; only the last baseplate in the expansion chain can have the I/O Bus Termitor Plug installed. Unused I/O Bus Termitor Plugs can be discarded or saved as spares. If an expansion system has only one expansion baseplate, the I/O bus can be termited by installing as the last cable, the 50 foot (15 meter) I/O Expansion cable, catalog number IC693CBL302 or IC693CBL314. These cables have the termition resistors installed in the end that connects to the expansion baseplate connector. You can also build a custom cable with termition resistors d to the appropriate pins for installation at the end of the bus. C C-6 Series 90-30 PLC I/O Module Specifications – 2000 GFK-0898F Shield Treatment All GE Fanuc factory de cables are de with a continuous, or 100% shield. This means that the braided cable shield is connected to the metal shell of the connector around the entire perimeter of the connector. This provides a low impedance path to frame ground for any ise energy that is coupled onto the cable shield. For custom length cables de per Figure 10-18, the best ise immunity is achieved when using a metalized connector cover that kes contact with the cable’s braided and foil shielding and with the connector shell on the termiting end. te It is t sufficient to only solder the drain to the connector shell.
