Troubleshooting Guide

SA-NET To Smart Switch To 27SA or 28SA

1) Connect the PC directly to the Smart Switch using the C3 cable connection, on the "SK-SS SMART SWITCH PC/TERMINAL NETWORK" sheet provided with this guide. Do not connect the readers at this time.

Verify the Smart Switch DIP switches are set for the SA-NET software. This information is located on the instruction sheet provided with this guide.

2) Check the communications between the Smart Switch and the PC. When you power up the Smart Switch, the Port A LED should be on.

**If the port A LED is not on, verify the switch settings again.

Load SA-NET, and go to the Setup Menu (ALT-S).

Select Configure Location, and enter ALT-R (Readers), ALT-S search for readers. Select the number of tiers in the network (1,2,or 3).

The Port A LED will turn off, then turn back on again when SA-NET is searching path A.

Next the Port A LED will turn off, and the Port B LED will turn on when SA-NET is searching path B.

These steps will repeat for Ports C & D. When the searching is complete, the Port D LED will stay on.

If the ports change correctly, then go to step #4.

** If the LED’s do not change ports, go to step #3.

** If you have found all the readers, EXIT (ALT-X) and save the settings. Exit from the Location Configuration Menu (ALT-X), and then go to step #9

3) If the LED’s did not change ports:

Verify you are connected to the proper COM port on the PC.

Verify the wiring by using the C3 cable connection on the diagram provided with this guide.

Verify the switch setting for the proper Tier, on the diagram provided with this guide.

If all the above is correct, then the Smart Switch could be defective.

** Once the Smart Switch is working, go to step #4.

4) Now that the PC is communicating to the Smart Switch, we are going to verify that all the readers will communicate with the PC. Unplug the Smart Switch power supply and connect a reader into Port A. Plug the Smart Switch power supply back in, and notice that the Port A LED is on.

Now the prompt to Enter Password should appear.

Press 1,2,3,4 Enter (this is the default password), and the Main Menu should appear.

** If you do not see the Enter Password prompt, or if the Main Menu does not appear, go to step #5.

While you are in the Reader Menu, lets assign the reader a name. Select System Settings, then Reader ID, and enter a name for the reader.

Repeat step #4 for the rest of the readers in the system.

** After all the "Reader ID’s" have been assigned, go on to step # 8.

5) Use a DC volt meter to measure the voltages on the terminal block of the reader. Locate pins labeled Communications 1,2,3,4,5. Pin number 1 is ground. Connect the black lead of the meter to pin 1. Use the red lead to read the voltages on pins 2 through 5.

Pin 2 (Receive Data, RXD). The voltage should read between -5 VDC to -12 VDC. This voltage comes from the PC. If the voltage is wrong or missing, disconnect the reader from the port, and measure the voltages at the reader (should be 0.0 VDC), and at the Smart Switch (should be between -5 VDC to -12 VDC).

Pin 3 (Clear to Send, CTS). The voltage should read between +5 VDC to +12 VDC. This voltage comes from the PC. If the voltage is wrong or missing, disconnect the reader from the port, and measure the voltages at the reader (should be 0.0 VDC), and at the Smart Switch (should be between +5 VDC to +12 VDC).

Pin 4 (Request to Send, RTS). The voltage should read between -5 VDC to -12 VDC. This voltage comes from the Card Reader. If the voltage is wrong or missing, disconnect the reader from the port, and measure the voltages at the reader (should be -9.5 VDC) and at the Smart Switch (should be 0.0 VDC).

Pin 5 (Transmit Data, TXD). The voltage should read between -5 VDC to -12 VDC. This voltage comes from the Card Reader. If the voltage is wrong or missing, disconnect the reader from the port, and measure the voltages at the reader (should be -9.5 VDC) and at the Smart Switch (should be 0.0 VDC).

** If the voltages are wrong, then verify wiring the C1 cable connection on the diagram provided with this guide.

** If the voltages from the PC are too low, then try another COM port, or another PC.

** If there are any voltage on pins 2 or 3 without the Smart Switch connected, then the RS232 port on the reader might be defective.

** If the voltages on pins 4 or 5 from the reader (-9.5VDC) are bad, then the RS232 port on the reader might be defective.

** If the voltages are good, go on to step #6.

6) Depress the ESC key a couple of times, and the Enter Password prompt should appear. If it does not, then try another reader; that reader might be defective.

7) Repeat step #4 until you get all the readers working.

8) Now that you are communicating to all the readers, unplug the power supply from the Smart Switch and connect all the readers. Now plug the power supply back in and repeat step #2. ** This time you should see SA-NET find all the readers.

9) Now go to the ‘Link Menu’ (ALT-L) for SA-NET, and Select Reader. Highlight

the reader you wish to connect, and press Enter. Next, enter the password and you will see the Main Menu appear.

***** If you are still having problems, or think you might have a defective Card Reader or Smart Switch, call Secura Key Technical Support before sending anything to us for repair.
