Wiring European connector
To remove the terminal block from the base, loosen the screw that secures the terminal block to the base, then firmly grasp the terminal block and pull. Do not pull the block out with wires as this may loosen or damage the wires or connectors. Refer to the 3301 Field Wiring Diagram Package for typical I/O modules for recommended wiring. Also, do not remove more than 6 mm (0.25 in) of insulation from the wire. 3301/20 Operation and Maintenance 4 I/O Module Description 25 4.1.4 Cable Pin Output Cable Number 02290860 Host (or Rack Interface Module) Cable number to external modem 130118 -- Host computer to 3301 rack RS-232 interface cable 4 I/O module description 3301/20 operation and maintenance 26 Cable number 132632 -- Host computer to 3301 rack cable RS-422 PVC cable number 132633 -- Host computer to 3301 rack cable RS-422 Teflon 3301/20 operation and maintenance 4 I/O module description 27 Cable number 130119-01 Host computer to RS-232/422 converter cable number 130120 -- RS-232/42 converter to 3301 rack cable (RS-422) -PVC insulated 4 I/O module description 3301/20 Operation and maintenance 28 Cable number 130121 -- RS-422 extension cable number 130122 -- RS-422 3301 rack to 3301 rack cable PVC insulated 3301/20 Operation and maintenance 4 I/O module description 29 Cable number 131106 -- RS-232/422 converter to 3301 rack cable (RS-422) -Teflon insulated cable No. 131107 -- RS-422 350 rack to 3301 rack cable - Teflon insulated 4 I/O module description 3301/20 Operation and maintenance 30 4.2 Data manager I/O module Data Manager I/O module must be installed behind the power supply between the power input module and the rack interface I/O module (in a rack mounted or panel mounted rack) or above the power supply between the power input module and the rack interface I/O module (in a bulkhead rack). The function of the data manager I/O module is to connect the 3301 rack to the TDI or DDI communication processor. Each port can connect up to 24 channels, from the 3301 rack to the communication processor. See the table on page 10 for the different options available. 1) Used to transfer static information from port 1 of the 3301 rack to the static connector on the communication processor. 2) Used to transmit dynamic information from port 1 of the 3301 rack to the dynamic connector on the communication processor. 3) Used to transfer information from port 2 of the 3301 rack to a static connector on the communication processor. 4) Used to transmit dynamic information from port 2 of the 3301 rack to the dynamic connector on the communication processor.
Note: 3301 monitoring system supports DDI and TDI communication processors.
Note: If you remove the Rack Interface Module, the Data Manager I/O will stop. 3301/20 Operation and maintenance 4 I/O module description 31 4.2.1 Cable pin output cable number 129,386-01 3301 Static to TDI cable cable number 12,937-01 3301 Static to DDI cable 4 I/O module description 3301/20 Operation and maintenance 32 Cable number 02,290,160 Dynamic data cable DDI/TDI 3301/40 Operation and maintenance 5 Maintenance 33 5 Maintenance This section describes how to verify that the Rack Interface Module and I/O Module are working properly. When performed correctly, the module can be installed in or removed from the rack when the rack is powered up. Refer to the Rack Installation and Maintenance Manual (part number 129766-01) for the correct procedure. 5.1 RIM Host Port Test Utility Use the RIM Host Interface Test Utility to verify that the host ports on the Rack Interface Module and the Rack Interface I/O Module are working properly. Before running the RIM host port test utility, connect cable 130118 -- (host to 3301 rack RS-232 interface cable) between the configuration port connector on the front of the Rack Interface Module or the host connector on the Rack Interface I/O Module and the computer where the utility is installed. For more information about this utility, refer to the 3301 Monitoring System Rack Configuration and Utilities Guide and Rack Configuration Software. 5.2 Performing a firmware upgrade may sometimes require replacing the original firmware that came with the 3301/20 Rack Interface Module (RIM). The following instructions describe how to delete existing firmware and replace it with upgraded firmware. After the firmware upgrade, RIM needs to be reconfigured using the 3301 Rack Configuration Software. The following items are required to perform the RIM firmware upgrade: large flat screwdriver. Grounding wrist strap * small flat screwdriver to upgrade firmware IC** Refer to Section 7 (Ordering Information) for part numbers. Users can use their own grounding wrist strap. 5.2.1 The installation procedure completes the following steps
