Technical Manual
Receiving Digital Data
Once the SX4e is set up as a Standard 19,200 bps Modem, there are two command options for receiving
digital data through the SX4e. These options are programmed by going off-hook with a DTMF telephone
connected to the SX4e and entering the following commands:
1) Press
* *
9 6
to set "always on" receive digital data mode, wait for dial tone, and go on-hook.
This command routes all incoming calls to the DB-9 serial port, not the RJ-11 port, and prepares
the SX4e to receive digital data signals which are recognized by the PC or other data device
connected to the terminal. When done receiving digital data calls in "always on" mode, reset the
SX4e to default mode by entering the command
* *
9 3
. All incoming calls are then routed to
the RJ-11 port and received as voice calls.
2) Press
* *
9 9
to set "one time" receive digital data mode, wait for dial tone, and go on-hook.
This command routes only the next incoming call to the DB-9 serial port, not the RJ-11 port, and
prepares the SX4e to receive digital data signals which are recognized by the PC or other data
device connected to the terminal. After receiving the next call, the SX4e automatically resets to
default mode and incoming calls are routed to the RJ-11 port as voice calls.
NOTE:
Regardless of which receive mode the SX4e is in as described in this section, the terminal
will always be able to make an outbound voice call from a telephone connected to the RJ-11 port, or
send a data call from a PC connected to the DB-9 serial port.
ANALOG (GROUP 3) FAX SERVICE - OPTIONAL
If your SX4e was ordered with the analog fax option, you
may send and receive faxes with an analog fax machine.
Plug In a Fax Machine
1) Locate the modular line port of your fax machine
and plug in one end of a standard phone cord
- see Figure 10
.
2) Connect the other end of the phone cord to the fax
port on the side of the SX4e
- see Figure 10.

2) Pick up the handset or press the off-hook button
of the fax machine.
3)
Press:
*

<destination fax number>
The SX4e will make the call automatically.
Receiving a Fax
With an analog fax machine connected to the SX4e, there are two command options for receiving
an incoming fax. These options are programmed by going off-hook with the fax machine or a DTMF
telephone connected to the SX4e and entering the following commands:
1) Press
* *
9 2
to set "always on" receive analog fax mode, wait for dial tone, and go on-hook.
This command routes all calls to the RJ-11 port and prepares the SX4e to receive analog fax
signals which are recognized by the fax machine connected to the terminal. When done receiv-
ing analog fax calls in "always on" mode, reset the SX4e to default mode by entering the com-
mand
* *
9 3
. All incoming calls are then routed to the RJ-11 port and received as voice calls.
2) Press
* *
9 5
to set "one time" receive analog fax mode, wait for dial tone, and go on-hook.
This command routes the call to the RJ-11 port prepares the SX4e to receive only the next call
as analog fax signals which are recognized by the fax machine connected to the terminal. After
receiving the next call, the SX4e automatically resets to default mode and incoming calls are
routed to the RJ-11 port as voice calls.
NOTE:
Regardless of which receive mode the SX4e is in as described in this section, the terminal will
always be able to make an outbound voice call from a telephone connected to the RJ-11 port, or send
a data call from a PC connected to the DB-9 serial port.
