Integrating GSP-1620 Modems into OEM Products

Note

The modem signal naming convention assumes that the modem is the

DCE and that the user application is the DTE.

 

 

DTR/DSR Signal and Power On/Off

 

An active DTR on any of the three serial ports (Data, Control

 

or Diagnostic) turns on the GSP-1620 modem (if DC power is

 

applied first). The modem then boots up from the shut-down

 

state and asserts DSR to indicate that it is booted up and

 

ready to communicate.

 

The modem starts its power-down sequence only after the

 

DTR lines on all three serial ports connected to the modem

 

are de-asserted for a minimum of one second. Just before the

 

modem powers off, it de-asserts DSR to let the application

 

know that it is okay to remove DC power to the modem

 

without risk of losing volatile data.

 

This mode of operation is useful in cases where power to the

 

modem as well as the rest of the system might be turned off

 

periodically to conserve battery power.

 

In case the modem “hangs up” and the watchdog circuit does

 

not reset the modem, you can reset the modem by pulling the

 

MODULE_RESET_N low for a period of 5 seconds or more and

 

releasing it to allow it to float. Pulling the line low has the

 

effect of a power-on reset and not just a watchdog reset.

Caution

The watchdog circuit is internal to the modem and is a protection against

 

a possible crash of the modem software. The RESET line should be

 

used only as a last-resort method of resetting the modem when the

 

application is sure that the modem is not responding to any commands.

 

Asserting the RESET line can result in loss of non-volatile data,

 

including the current state of the modem.
