➤
Standard Input Voltage. Input voltage 5–30 Vdc. Power from an external source, through the USB-B
connector, or through the DB-9 connector.
➤
Easy Configuration. Uses standard and extended AT command set.
➤
Compression and Speed. Allows data speeds from 300 bps to 56 kbps. Supports V.44 and V.42bis
data compression.

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).

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.
- Page 2 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.
