Give this a try...
After Hooking Up the Tech 2 to the Laptop... 'Exercise' the 4 Pair Twisted RJ-45 Connector that gets plugged into the Tan DB9 Adapter attached to the USB-Serial Port Adapter a few times... just to ensure that the (8)12kt Gold Wires are mating up correctly in between. Do the same action where the Silver Flat Ribbon (4 Pair Twisted) Cable RJ-45 Connector Plugs into your Tech 2.
Then after you first Click on the TIS2000 Desktop Icon and open TIS2000 Software to the Main Screen... Before you Click on this
Tech 2 View Icon...
.... Select the
Configuration Tab (Highlighted inside the Red Rectangle of the Attached Image) and look there for the
I/O Management (Input - Output). Then select either the
Tech 2 Option or the
Pass-Thru Option from the Menu. First High-Light the
Tech 2 Option (White Text on a Dark Blue Border) and then Select the
Properties Tab on the Right Side of the Menu. From there, you can Select your
COM1-4 Port and
Baud Rate.
Use the 115200 Setting :
If you then select the
Tech 2 View Option on the Laptop Screen, after turning on the Tech 2 Scanner, after it finishes its Boot Up Self-Diagnosis, you can use your Mouse to select any of the
Tech 2 View Keypad Buttons or Function Keys (F1-F4, etc.) BOTH screens for the
Tech 2 and the laptop
should simultaneously change. If these actions work either from the
Tech 2 itself or from the Laptop
Tech 2 View Mouse on Keys Selection actions, then you should have Good Hardware Connections and Good Bi-Directional COM Port Communications. The SPS Activities should work after following these steps.
