Telular SX5D - Manual (Page 35)

Baud Rate AT Commands
The SX5 will accept AT commands to setup the port speed. If you want to change the SX5 port
speed for a session or keep the change permanent, or if you just want to see the profile settings,
use the following AT commands from a terminal application (like HyperTerminal).
NOTE: Make sure DTE Fallback is OFF before making changes to the baud rate.
Digital Fax Setup
The SX5 is capable of receiving and sending faxes via a personal computer using a standard
RS232 serial port. The PC application and modem setup must be able to support software flow
control. To setup flow control properly, follow the instructions for setting up a standard modem
connection in Appendix A of this manual with the following changes.
HINT: Setup a separate modem for PC fax and a separate modem for PC circuit switched data
connections. This way you will not have to make changes to the modem settings every time you
want to use fax or data.
1. Change the flow control of the standard modem to enable software flow control.
2. Change Extra Settings from AT&D1 to AT+IFC=1,1 &d1. This enables software flow control
on the SX5.
3. On the SX5, select the serial port for your data connections by entering the MENU, then
select Settings, then Fax Port, then Data Port, and then Serial Port (DB9).
4. Run your PC fax application using this new modem connection for receiving and sending
faxes.
GPRS (Packet Data) Connections
The SX5 will allow GPRS connectivity if your network service provider has this feature
available. GPRS allows packet data connections at higher speeds than conventional circuit
switched (dial-up) connections. A GPRS Kit can be used when you are connecting with GPRS
service. This kit contains a serial cable and a setup CD for installation on a standard personal
computer. Contact your service provider or nearest dealer for more information.
Analog Modem Support
The SX5 FAX phone model supports connectivity with an analog modem. A PC with a modem or
other devices that use a modem, like a credit card swipe Point Of Sale (POS) machine, can be
connected to the RJ-11 jack (marked with a telephone icon) and used seamlessly.
Data Port Setup
The RJ-11 voice jack on the SX5 (the jack marked with a phone icon) can be configured for
voice (default setting) or analog modem data. If the jack is configured for analog data, the
bypass string for voice calls must be entered before a voice call can be made. In voice mode,
data transmissions are routed through the DB-9 port. To send data via an analog modem while in
voice mode, use the analog bypass string.
1. Press the MENU key.
2. Select Settings, then select Data Settings.
3. Select Data Port, then select Analog (RJ-11) or Serial Port
(DB9).
Using the Bypass String
A bypass string can be used when the default port is not set to analog data. This string needs to
be appended to the beginning of the phone number that the modem is dialing.
1. Go off-hook on the RJ11 analog modem jack (jack with phone icon).
2. Dial the bypass string and number: # * 19 * 2 # <number>.
Modulation
The analog modem interface supports the following standards and data rates. The SX5 also sup-
