| The NMEA Buffer has ISO-Drive™ technology on the outputs and OPTO-isolation on the input which enables you to connect the NMEA 0183 Buffer with complete peace of mind. |
| The stainless steel housing makes the device rugged, sturdy and gives increased durability. The metal case also acts as an RF Shield making the device an ideal addition to commercial installations. |
| To make installation quick and simple the PRO-NBF-1 features 2-part pluggable connectors that allow use of screw terminals*, and a professional DIN Rail mounting system (DIN Rail not included). The device can also be mounted directly to the bulkhead. |
| The optional strain relief brackets can be provided to ensure reliable professional cable management. |
| Helpful LEDs indicate power, input, and output operation. |
| FEATURES |
| One Opto-Isolated Input |
| Six ISO-Drive™ outputs |
| Outputs automatically track the input baud rate |
| RS-232, RS-422 and RS-485 Listener compatible |
| BENEFITS |
| ISO-Drive separates the Listener from the Talker to protect both the NBF-3 and each connected device |
| Wide compatibility meaning simplified installation |
| Simple installation saves time and money and provides peace of mind |
| Type Approved (RINA) |
