Features
The DSP19.2 modem is specifically designed for harsh environments typically associated in
utility substations and industrial facilities. Though functionally similar to commercial modems,
the DSP19.2 provides the following unique features that make it well suited for utility and
industrial applications.
y
Packaged in a rugged, compact enclosure for industrial applications.
y
Leased-line interface protected with heavy-duty surge protection devices.
y
Built-in hardware watchdog timer for software lock-up prevention without
requiring human intervention, making it ideal for unmanned locations.
y
Works within an extended temperature range of -40ºC to +85ºC.
