Connecting the Diagnostic Cable

The Diagnostic cable lets you:

• Service-program GSP-1620 modems, using the Globalstar User Terminal Program Support Tool (UTPST). For more information about the UTPST, see UTPST Overview on page 3-2.

• Monitor or verify some modem functions, using the QUALCOMM Globalstar Modem Operation Monitor. For more information, see the QUALCOMM Globalstar Modem Operation Monitor User’s Guide, 80-99399-1.

 

The cable includes an optional AC adapter. If a DC power

 

supply is not available on your bench, you can power the

 

modem with the AC adapter on the Diagnostic cable.

 

The Diagnostic cable also includes a switch box that controls

 

whether the cable’s DTR (Data Terminal Ready) signal is

 

asserted (“POS 1 DTR to GND”) or de-asserted (“POS 2 DTR

 

Open” or “POS 3 Not Used”). When DTR is asserted, the

 

modem powers up immediately if power is provided. Before

 

powering down the modem with this cable attached, you must

 

set this switch to “POS 2” or “POS 3.”

Note

On the switch box, “POS 2 DTR Open” and “POS 3 Not Used” are

functionally equivalent. Some cables are equipped with a two-position

 

 

switch box and do not have “POS 3.” The switch positions for these

 

cables are “POS 1 DTR to GND” (DTR asserted) and “POS 2 DTR

 

Open” (DTR de-asserted).

Tip

When the Diagnostic cable is connected but you are not using the

 

UTPST to service-program the modem, leave the Diagnostic cable

 

switch in the “POS 2 DTR Open” (de-asserted) position.
