Pin Signal

Name IN/OUT

Type Description

1 –RI O RING (Active Low). Incoming ring signal from phone.

Ring Indicate. –RI output ON (low) indicates the presence of an ON segment of a ring

signal on the telephone line. The modem will not go off-hook when –RI is active; the

modem waits for –RI to go inactive before going off-hook.

2 –DCD O Data Carrier Detect (Active Low). –DCD output is ON (low) when a data connection is

established and the module is ready to send/receive data.

3 –DTR I Data Terminal Ready (Active Low). The –DTR input is turned ON (low) when the DTE is

ready to communicate. –DTR ON prepares the modem to be connected, and, once

connected, maintains the connection. –DTR OFF places the modem in the disconnect

state under control of the &Dn and &Qn commands.

4–RESET I Device Reset (with pull-up). The active low –RESET input resets the device logic and

returns the configuration of the device to the original factory default values or "stored

values" in the NVRAM. –RESET is tied to VCC through a time-constant circuit for “Power-

on-Reset” functionality. The module is ready to accept commands after a fixed amount of

time after power-on or reset.

5 VCC PWR

DC Input Power. 3.3 V or 5 V DC power, depending upon the build.

6 –CTS O Clear to Send (Active Low). –CTS is controlled by the module to indicate whether or not

the module is ready to transmit data. –CTS ON indicates to the DTE that signals on TXD

will be transmitted. –CTS OFF indicates to the DTE that it should not transfer data on TXD.

7 –RTS I Request to Sent (Active Low). –RTS signal is used for hardware flow control. –RTS

input ON (low) indicates that the DTE is ready to send data to the modem. In the

command state, the modem ignores –RTS.
