Functional Overview
The SEL-9192 is a 56 kbps dial-up modem built to withstand the extremely harsh conditions in a utility envi-
ronment. Connect RTUs, communications processors, and other equipment for dial-up or dial-out engineer-
ing access or data acquisition through the DB-9 serial or USB-B connectors. Power the SEL-9192 with the
optional power supply, or internally through connected USB-B or DB-9 serial ports. Configuration is simple
with the extended AT command set (listed in Table 1).

Applications
The SEL-9192 is ideally suited for point-to-point and point-to-multipoint dial-up access applications in harsh
environments and extreme temperatures. Use the SEL-3025 Serial Shield®in conjunction with the SEL-9192 to encrypt
all serial traffic across the dial-up link.
Dial-Up or Dial-Out
Figure 1 shows typical point-to-point dial-up access for data acquisition of a device. Connect the SEL-9192 to individual
IEDs or connect to a communications processor to retrieve data for several IEDs in a given location. Devices that support
dial-out communication can send events or other information to the host computer.
Figure 1 Dial-Up or Dial-Out Point-to-Point SCADA Communication
Figure 2 illustrates use of the SEL-9192 in a point-to-multipoint SCADA communications scheme. The host computer
can access any number of dial-up devices by serially dialing each SEL-9192 connected to those end devices.
Figure 2 Dial-Up Point-to-Multipoint SCADA Communication
Add an SEL-3025 to your dial-up network to create a secure dial-up environment, as shown in Figure 3.
Figure 3 Secure Dial-up Engineering Access Channel
Manage IED engineering access through a communications processor such as the SEL-2032, SEL-3530 RTAC, or the
SEL-3354 Embedded Automation Computing Platform, as shown in Figure 4. Connect the modem via USB-B or the
SEL-C431 cable to the communications processor.

Use an SEL-3610 Port Server to create a modem pool with as many as eight port-powered SEL-9192 modems and as
many as nine additional externally-powered SEL modems, as shown in Figure 5.
Figure 5 Modem Pool Application
Configuring
To configure the SEL-9192, install the SEL USB-to-
UART driver (contained on the CD and also available on
the SEL website), then connect a USB-B cable into the
USB port of the modem and into a USB-A port of your
PC.
Apply power to the modem in one of the following ways:
➤Connect a USB-B cable to the modem and to the
USB-A connector on your PC. The modem is auto-
matically powered through USB. Note that if your
PC runs on Windows®, you must first install the
SEL USB-to-UART driver.
➤Connect an external +5 Vdc power supply (SEL
part number 230-0600) by inserting the 2.5 mm
barrel connector of the supply into the mating jack
on the modem.
➤If the DTE device supports +5 Vdc power output
on serial Pin 1, connect an SEL-C431 cable to the
modem and DTE device. Locate the 5 V Pin 8
switch positioned between the Telco and DB-9
connectors. Slide the switch to the ON position to
use port power on Pin 8 or slide the switch to the
OFF position to use a straight-through serial cable
with no power on Pin 8.
Use the SEL-C431 cable to connect to an SEL DTE
device in a DNP dial-out scenario. The SEL-C431 cable
can be no more than three meters (10 ft) in length.

terminal emulation programs, to communicate with the
modem via USB or serial communications. Install the
modem driver by following the directions for your
version of Windows.
For Windows XP perform the following steps:
Step 1. Ensure that you have installed the SEL
USB-to-UART driver and downloaded the
Windows XP modem driver from the
SEL-9192 modem webpage on the SEL
website.
Step 2. Connect the SEL-9192 modem to the PC
using a USB-B cable. Wait until the
modem power LED is illuminated.
Step 3. If Windows presents a Welcome to the
Hardware Update Wizard dialogue, click
Cancel.
Step 4. From the Start menu, open the Control
Panel and double-click System.
Step 5. On the Hardware tab, click Device

location (Advanced).
Step 9. Click Browse and navigate to the
SEL-9192 Modem CD or the location
where you downloaded the Windows XP
modem driver from the SEL website, then
press Next.
Step 10. Wait for the driver installation to finish,
then click Finish.
For Windows 7, 64 bit perform the following steps:
Step 1. Ensure that you have installed the SEL
USB-to-UART and downloaded the
Windows 7 modem driver from the
SEL-9192 modem webpage on the SEL
website.
Step 2. Connect the SEL-9192 modem to the PC
using a USB-B cable. Wait until the
modem power LED is illuminated.
Step 3. From the Start menu, open Control
Panel > System > Device Manager.
Step 4. Under Other devices, right-click Analog
Modem and select Update driver.
Step 5. Select Browse my computer for driver
software.
Step 6. Select Let me pick from a list of device
drivers on my computer.
Step 7. Double-click Modems from the list. Your
PC will give a list of available standard
modem drivers.
Step 8. Scroll down the Manufacturer list to
Conexant. Under Models, select
Conexant Compatible Internal
V90,K56Flex,Voice,Speakerphone, then
click Next.
Step 9. Click Ye s on the warning about updating
drivers.
Step 10. Click Close to finish the installation.
Configure the modem using a terminal emulation
program or ACSELERATOR QuickSet®SEL-5030
Software’s terminal screen with AT commands. Enter
AT (ATtention) followed by the command, parameters, if
any, and a carriage return. The modem will reply with OK.
AT Command Example
This example uses the SO command to instruct the
modem to automatically answer after it detects two
consecutive rings.
ATSO=2 <Enter>
OK
Table 1 contains basic AT commands. Table 2 through
Table 6 contain extended AT commands. The general
format is ATXn, where Xis the command given in the table
and nis a parameter required for some of the commands.
Ensure that you save the settings into NVRAM when you
are finished with the AT&W0 command so that the
settings will remain through power outages.

STE Command
Use the -STE=ncommand to enable/disable Line-In-Use
and Extension Pickup options. Use Table 4 to determine the
value of nfor this command in your installation scenario.
If the line is in use and the modem issues an ATDT
command to dial out, the modem will not go off hook
and will display a LINE-IN-USE result code. If the
modem is off hook and the extension is picked up, the
modem will drop the connection.
AT+MS Select/Force Modulation
Command
This command is useful if you need to force the modem
to specific modulations or line speeds.
+MS Modulation Selection
This extended format compound parameter controls the
manner of operation of modulation capabilities in the
modem in one command. See Table 5 for valid entries.
Below is an example of how to read the current settings
using the AT +M S ? command.
=>AT+MS? <Enter>
+MS: V90,1,300,33600,300,5600
%Q Line signal quality
Reports line signal quality (DAA-dependent). Returns higher order byte of the EQM value. Based on EQM value,
retrain or fallback/fall forward may be initiated if enabled by %E1 or %E2.

Basic Modem Result Codes
There are over 300 different result codes that the modem
will return in response to processing various AT
commands. The codes may be displayed in word (V1) or
numeric (V0) format by using the Vncommand. The Qn
command controls if the result codes are issued (Q0) or
not issued (Q1). The Xnand Wncommands and register
S95 determines which result code format the modem will
display to indicate the type of established connection.
See Table 7 for the most common result codes.
