There are a few more things to check so you can Sort Out the COM Port Issues:
(1) Connect the Tech 2 to the AC 110 to 12 Volts DC 1.5 Amp Power Supply but do NOT Turn the "GYMKO" Tech2 ON just yet.
(2) Connect whatever USB to DB9 Adapter you presently have to the Laptop USB Port and then attach the TAN DB-9 Serial Port to RJ-45 Dongle.
(3) Connect the Silver Flat Ribbon Cable to the Tech 2 S/S RJ-45 Female Port on the Tech 2
(4) Connect the other end of the Silver Flat Ribbon Cable male RJ-45 to the TAN Dongle Female RJ-45 Port.
(5) Boot up the Laptop and open your TIS2000 Program from the Desktop Icon.
Then 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, once 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.
