Navionics Research is pleased to introduce the B202-v.108 Modem — a new release of our non-proprietary modem that is targeted for use at our radio telemetry/SCADA system customers!
This new modem constitutes a major re-design of our first-generation modem, the B202-v103; and it offers the following new features:
- 100% compatibility with existing telemetry/SCADA systems that presently use Calamp DM-3282 modems and/or SCADAmetrics B202-v103 modems.
- 2.5KV of isolation on the RTU Serial Port Interface, for enhanced lightning/surge protection.
- Serial Port Pins [4,6] and [7,8] are internally jumpered, so that Rockwell/Allen-Bradley-based PLC’s, such as the MicroLogix, ControlLogix, CompactLogix, and SLC500 can be connected using a standard 9-pin serial cable.
- Ability to Drive Lower-Impedance (600-∞ Ω) Audio Loads with an Adjustable 0-2 Vpp (0.707 Vrms) Signal.
The most notable new feature is the 2.5KV of isolation on the serial port. Isolation techniques are widely utilized to contain damage from lightning strikes and voltage surges, and to prevent the damage from spreading throughout a control panel. To our knowledge, the B202-v108 is the first and only Bell-202 radio telemetry modem that offers 2.5KV of serial port isolation!
B&B Electronics, a company that manufactures a wide range of isolation equipment deployed by Navionics Research, has authored an interesting article on the subject of isolation HERE.
The datasheet for the B202-v108 modem is available HERE.
The B202-v108 is over-the-air compatible with our existing Bell 202-based wireless telemetry systems; and it can be easily installed as a durability upgrade, where it is installed between the existing telemetry radio and RTU/CPU.
Are you interested in upgrading your system with this exciting new modem?… Or are you interested in learning more about it? Give us a call, and we’ll be glad to discuss it with you in further detail.
