Use with a Variety of DTE Devices and Systems
The DTE port of the modem can be connected to a hot box detector, PLC, RTU, recorder, etc.
Expanded Operating Temperature Range
The modem will operate over a temperature range from -40C to +72C.
Line Speeds Up to 33.6K Baud
Auto-sensing allows the modem to operate at optimum line speeds. Line conditions are determined for each call.
Multiple DTE Speeds with Auto-Baud Detect
As controlled by the user-defined profile, the DTE port can be set to auto-baud detect or assigned a fixed speed.
Error Correction and Data Compression
All commonly used error detection and data compression schemes can be selectively deployed by establishing a preferred profile.
Auto-Answer and Originate Modes
The modem will auto-answer incoming calls after a predetermined number of rings. It can also be used to originate outgoing calls.
Includes ModemConfig Application Software
MICRO‑AIDE's ModemConfig Application can be downloaded and used without charge. It is used to define, install and review the modem's operating profile. Custom profiles can be easily created to suit a variety of rail signal products.
Proven Design Based Upon MICRO‑AIDE's LPM
The design details of the PIM are based upon those of the LPM. Thousands of LPMs have been used by DOTs throughout North America.
