  OCI Wireless Data Link
OCI Wireless Data Link

Fast, Reliable, Wireless Communications
Arrick Robotics is an authorized dealer for the LAWN wireless data link from OCI. The LAWN links RS-232 serial data ports together using high frequency spread spectrum radio transmission. Each LAWN unit contains a radio transeiver and microprocessor to provide error-free communication. Data is packetized and checked for accuracy after transmission then resent if errors occur. The result is error-free, transparent data communications. Parameters are set with PC-based software and retained in the unit.

The LAWN is perfect for communication between a desktop computer and a mobile robot such as our Trilobot.

Networking multiple LAWN units
The LAWN wireless data links can be networked up to 20 users with a typical coverage area 10,000 sq/ft. LAWN units can also be setup as repeaters to extened the range.
