Factory Set Pin Configuration
The key features of the UART in the modem mode are as follows:
l
16C750 compatibility
l
Baud rate from 300 bits/s up to 115200 Kbits/s, autobaud
l
Configurable data format:
l
Data bit: 5, 6, 7, or 8 bits
l
Parity bit: even, odd, none
l
Stop bit: 1, 1.5, 2 bit(s)
l
Hardware flow control RTS/CTS
l
Software flow control using XON/XOFF characters
The Enabler IIIG module is designed to be used like a DTE device.
Default settings are 8 data, 1 stop, no parity, and auto-baud. DTR may be used to force the
modem into AT command mode from online data mode (See AT Command Document,
command AT&D). RTS and CTS may be used for hardware handshaking. DSR is always active
(connected to ground) while the modem is on. RING may be used to alert the host to a variety
of incoming calls.
The serial interface is 1.8V logic. By default, hardware handshaking (AT+IFC) is enabled. The
module will be expecting the RTS line to be low before it will transmit data. If the integrator
does not wish to use flow control, please see below for minimal serial implementations:.
For a minimal Serial implementation use one of the following two configurations:
Configuration 1:
l
Connect RxData (pin 15) and TxData (pin 21) to the COM port serial data lines.
l
DTR (pin 17) and RTS (pin 11) be pulled up through a 100K resistor if not used.
l
The user must set AT+IFC=0,0 to disable flow control to communicate with the modem.
Configuration 2:
