  • Supports speeds up to 56K
  • Can be configured through the phone line from a distant location
  • Callback security prevents unauthorized access
  • Rated for -30° to +70°C operation
  • Tough enough for Class I, Div. 2 (Zone 2) hazardous locations
  • DIN Rail or flat panel mounting
  • DC powered - No more bulky AC adapters
  • Five year guaranteed availability for OEMs

 

Why an Industrial Modem - Industrial grade modems are designed for industrial environments. Their rugged packaging and protected circuitry keep them working under conditions that may cause cheap office-grade modems to fail. Industrial applications are demanding - it gets hot, it gets cold - the power browns out or spikes wildly - and you need a reliable industrial modem that can keep on going.

The Callback Remote Security feature allows you to password-protect a remote (answering) VT-MODEM-5 to restrict call-in access. The remote VT-MODEM-5 will only establish a connection with a local (dialing) modem after the password has been received from the local site. Refer to the VT-MODEM-5 Callback Security topic for more information on this feature.

This security feature can be enabled by clicking the Enable Remote Callback Security button.
