5.1.10 Troubleshooting the Front Panel Serial Port
The front panel serial port can be used for SecureSync configuration or to obtain select data.
The serial port is a standard DB9 female port. Communication with this port is via a standard
DB9F to DB9M serial cable (minimum pinout is pin 2 to 2, pin 3 to 3 and pin 5 to 5) con-
nected to a PC running a terminal emulator program such as Tera Term or Microsoft Hyper-
Terminal. The port settings of the terminal emulator should be configured as 9600, N, 8, 1
(flow control setting does not matter).
If the terminal emulator program does not display any data when the keyboard <Enter> key is
pressed, either SecureSync is not powered up or there is a problem with the connection
between SecureSync and the PC.
Using a multimeter, ring out the pins from one end of the serial cable to the other. Verify the
cable is pinned as a straight-thru serial cable (pin 2 to 2, pin 3 to 3 and pin 5 to 5) and not as
a null-modem or other pin-out configuration.
Disconnect the serial cable from SecureSync. Then, jumper (using a wire, paperclip or car key,
etc.) pins 2 and 3 of the serial cable together while pressing any character on the PC’s key-
board. The character typed should be displayed on the monitor. If the typed character is not
displayed, there is a problem with either the serial cable or with the serial COM port of the
PC.
Refer to "Setting up a Terminal Emulator" on page512 for more information on using a ter-
minal emulator software to communicate with SecureSync via serial port.
5.1.11 Troubleshooting the Front Panel Cooling Fan
The cooling fan (located on the front panel, to the right of the LED time display) is a tem-
perature controlled cooling fan. Temperature sensor(s) determine when the cooling fan needs to
turn on and off. It is normal operation for the cooling fan to not operate the entire time
SecureSync is running. It may be turned off for long periods at a time, depending on the ambi-
ent and internal temperatures.
