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 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.
