Introduction This document will provide instruction of how to create an EX90 console cable using a Nokia CA42 USB Data Cable and console into a unit. Core Issue There may be situations where consoling into an EX90 can solve an issue that is not related to hardware. A console cable for the EX90 is not provided by default or readily available for purchase, but, one can be assembled relatively easy. Resolution Gather the Necessary Tools and Equipment The following tools will be necessary to create the EX90 console cable: Nokia CA-42 USB Data Cable or compatible cable. If you're not using the OEM cable, ensure it contains the PL2303 chip. This example will be using the compatible found here. RJ45 Crimp Tool RJ45 End Optional Tools Soldering Iron Solder Wire Strippers Verify the Cable Pin-outs Before creating the cable, locate the TX, RX and GRD. Pin-out for the Nokia OEM cable: Pin-out for the compatible cable used in this example: Pin-out for the compatible cable used in this example: Note: All compatible cables may not have the same color wires. If you're not sure of the pin-outs of the cable you're using, cut off the connector end of the cable leaving a couple inches connected to it. Use a multimeter to locate the TX,RX and GND. Prep the Cable Strip the sheathing off the TX, RX and GND. It's a good idea to solder the ends of the wires to make them easier to work with. Create the Cable Crimp the RJ-45 on the end of the USB side of the cable. Ensure the TX, RX and GND are in the correct positions before crimping. Connecting to an EX90 Load the correct cable drivers OEM Cable Drivers. If you're using the CA-42 OEM cable, the drivers can be downloaded from here. Use guest/guest for the username/password. Click the link for PL2303 USB to Serial Drivers. For Windows, locate the file PL2303_Prolific_DriverInstaller_v1.7.0.zip. The file contains all of the windows drivers. For Mac, locate the appropriate driver based on your OS level Compatible Cable Drivers. For Windows, the Serial PS2303 driver from usbserialdrivers.com can be used. For Mac: OSX 10.5 and earlier usbserialdrivers.com OSX 10.6 osx-pl2303.sourceforge.net OSX 10.7 noelflash.com Connecting to the EX90 Console Locate The EX90 Console Port The EX90 console port is an 8P8C (RJ45) connection and is located on the bottom left corner of the unit. Connect to the Console Port Plug the 8P8C (RJ45) end into the console port. You'll have to lean the unit forward to plug the cable in. It might be a little awkward to do alone. If someone else is available, ask for their assistance. As a last resort, lay the unit down. Ensure you have something soft (like a towel) to lay the unit on. Connect the USB side to you laptop to PC or Mac. Connect using Windows Verify the COM Port In Windows, open Device Manager and verify the COM port of the USB-to-Serial Adapter. Configure a Terminal Emulator Session The following example uses Putty in Windows7. After connecting with the terminal emulator, you should have a connection to the EX90: Connect using a Mac This example will show connecting using the terminal application (Applications-->Utilities) using MacOSX 10.7. Verify the Value of the tty CD to the /dev directory and ls tty.* to list all the available tty. Start a Session Use the screen command along with the correct tty. Use the 38400 to set the baud rate (The baud rate of the ex90 console port is 38400). After connecting with the terminal emulator, you should have a connection to the EX90: This completes making an EX90 console using a CA42 USB data cable and connecting to the console port. ...

Core Issue There may be situations where consoling into an EX90 can solve an issue that is not related to hardware. A console cable for the EX90 is not provided by default or readily available for purchase, but, one can be assembled relatively easy. Resolution Gather the Necessary Tools and Equipment Soldering iron Solder RS232 to TTL/CMOS converter Alldav.com sells the one used here. Cisco does not recommend or endorse Alldav specifically. DB9 Enclosure Several options are available for the enclosure. This one is being used here. Cable w/RJ45 connector on one end Any type of cable with an 8P8C (RJ45) connector could used as long as pins 1,2,7 & 8 are connected. A standard RJ45 cable is being used here. You will also need wire strippers (not shown) and coudl need other ancillary tools such as a screwdriver. Prep the Cable Strip the sheathing from the wires that correspond to pins 1,2,7& 8. . Connect the RS232 to TTL/CMOS converter Connect the RS232 to TTL/CMOS converter to the cable and solder the connections. Wiring Diagram: Note: The colors used in the wiring diagram don't correspond to the color of the actual wires. Cable with RS232 to TTL/CMOS converter connected. . Install the Enclosure Cable with enclosure installed. The EX90 console cable is now complete. Make a Console Connection Locate the Console Port The EX90 console port is an 8P8C (RJ45) connection and is located on the bottom left corner of the unit. . Connect to the Console Port Plug the 8P8C (RJ45) end into the console port. You'll have to lean the unit forward to plug the cable in. It might be a little awkward to do alone. If someone else is available, ask for their assistance. As a last resort, lay the unit down. Ensure you have something soft (like a towel) to lay the unit on. Connect the DB9 to a USB serial adapter and connect to a laptop/PC. . Configure a Terminal Emulator Session Configure your terminal emulator with the following parameters. The example uses HyperTerminal forWindows; configuring your terminal emulator may vary slightly. .
