KB01247 - OmniStream Product Recovery

SKU: AT-OMNI-112, AT-OMNI-111, AT-OMN

Subject: OmniStream Product Recovery 

Steps:

  1. Introduction

This Guide is intended to provide you a recovery procedure for those rare cases where OmniStream Encoder / Decoder isn’t booting properly. You will be able to determine if the OmniStream device is requiring this recovery procedure or not by not able to reach the unit using IP, RS-232 and the front LED’s all being red.

In this recovery procedure, we will attempt to bring your device back to a normal operating state.

  1. Pre-Requisites

               1. Required Software

                      A. **A serial program such as H-Term 

                      B. OmniStream latest firmware

                          1. OMNI-111 - https://atlona.com/product/at-omni-111/#tab-firmware

                          2. OMNI-112 - https://atlona.com/product/at-omni-112/#tab-firmware

                          3. OMNI-121 - https://atlona.com/product/at-omni-121/#tab-firmware

                          4. OMNI-122 - https://atlona.com/product/at-omni-122/#tab-firmware

               2.  Required Hardware

                      A. PC / Laptop running Windows 7, 8.x, 10 with COM (RS232) port or USB to DB9 adapter

                      B. Connection to the same Network switch OmniStream Device is connected to RJ-45 cables

                      C. RJ-45 cables

                      D. RS-232 (DB9) to Phoenix captive screw cable –

                           1. Use wire strippers to remove a portion of the cable

                           2. Remove at least 3/16” (5 mm) from the insulation of the RX, TX, and GND

                           3. Insert the TX, RX, and GND wires into the correct terminal on the supplied Phoenix block. If using non-tinned stranded wire, press the orange tab, above the terminal, while inserting the exposed wire. Repeat this step for the TX, RX, and GND connections. Please use pins 2,3, and 5 respectively.

  1. Procedure    

          A. Open Terminal Emulator and break the boot sequence by entering this password "lYNaoS+G$0d". The default baud rate of the OmniStream device during the boot process is 115200(data 8, stop 1, parity none). Once the unit has been recovered successfully, it will default back to a baud rate of 9600(data 8, stop 1, parity none). It is recommended to verify the functionality of your DB9 to captive screw cable by sending commands on a working Omnistream device and monitoring proper feedback.

The “$0d” stands for carriage return. In H-term, you want to adjust the send on enter to CR 

With other programs please use the carriage return unique to the emulator. To interrupt the boot sequence, unplug the cat cable(if the unit is receiving power via POE) or the 48v captive screw(if using local power), plug power back into the unit and send the following command “lYNaoS+G” as many times as it takes to produce the following output. You will need to do this right after inserting power as you are trying to disrupt the boot-up process:

             B. Send the command “run nand_loaddevenv && run nand_choose_os”, expect the following feedback:

             C. Check which bank in Flash is active and set OS number to the other bank (1 or 2) by sending the “printenv osnbr” command. 

            D. If it's is 1, then next step change to 2. If its showing up as 2, then next step change to 1. Use the command “set osnbror 2” to accomplish this. You can verify with the “printenv osnbr” command:                      

           E. Run these commands to boot Linux “run nand_set_offs && run nand_loadbit && run                             nandboot_kernel”. You should see similar boot feedback:

           F. It’s now possible to log into the board via the serial interface and see which IP address has been assigned. Running the CLI interface will show the auto-IP address if the board is configured for DHCP and no DHCP server is present. You should be able to simply type into the command line of H-term and navigate the Omnistream CLI.

           G. Login into the unit using default admin Atlona credentials. (username: admin, password: Atlona)

           H. Verify the IP address by running the “IPCFG1” command for interface 1, or the “IPCFG2”         command for interface 2. If your Omnistream device does not have a DHCP assigned address, you can always assign the interface a static IP address. Simply choose an interface(if on a dual-stream     encoder/decoder), type “IPStatic1 or IPStatic2 192.XXX.XXX 255.XXX.XXX 192.XXX.XXX” See below:

          I. Make sure your PC / Laptop Network interface configured to the same IP range you configured the recovered OmniStream device to use.

          J. Login to the unit using the IP address and then upgrade the unit to the latest firmware using the appropriate firmware for your device.

 

         K. You can now reboot your device. It should be functioning as normal. You will see a mix of green and red LEDs on the front panel of the box.
