Extended Temperature range - SEVERE ENVIRONMENT - DC Power
Now available with a power input option of 12, 24 or 48 VDC. The input floats so ground loops are eliminated. The input total power requirement is under 3.5 watts. Power input can be from solar cells or regular battery. Wide voltage swings can be tolerated - temperature range of -30 to +150 degrees Fahrenheit - power input option of 12, 24 or 48 VDC -

The VRL-1 Variable Speed CSU/DSU that allows users to connect to the Digital Network without making obsolete their existing equipment. The VRL-1 performs Bell compatible encoding and decoding, system timing, the proper interface and complete diagnostics in a small reliable package. The VRL-1connects to the digital network at speeds of 56K, 19.2K or 9.6 K. At the 19.2K and 9.6K speeds, the terminal speeds and the line speeds are the same. At 56K, the VRL-1 can operate at 56K terminal speeds or it can provide speed adaptation, allowing connected terminals to run at speeds less than 56K. Speeds of 1.2K through 38.4K are possible in this mode.

The table on the Specifications  illustrates the products flexibility.  

• Using Programmable Logic Technology the VRL-1 provides the interface buffering to convert your terminal speed to 56K line signaling. This means that you can install your high speed digital lines today at 56K without having to upgrade your terminal equipment. In fact, the VRL-1 provides the appropriate interface and conversions. The process is completely transparent to your system. As an added benefit, you can also connect asynchronous devices.

• Adaptive Distance Compensation Circuitry Automatically analyzes your link and compensates for distortions. This assures that the VRL-1is tuned to the optimum performance for your particular installation, and eliminates the need for user adjustments.

• Interface Flexibility Assured The VRL-1 provides speeds from 56K down to 1.2K. Both V.35 and RS-232 connectors are provided as well as the interface circuitry.

• DIAGNOSTICS THAT WORK FOR YOU and with you to provide the tools needed to manage your circuits. All the appropriate telco loopbacks are provided. The BAT VRL-1 can be used to assist you to trouble shoot every part of your link.

• The VRL-1 is covered by BAT Electronics' EZ Lifetime Warranty
