BU-2CAN Manual 1.0 SmaRT BU-2CAN Base Unit The BU-2CAN base units are the machine mounted units of a SmaRT Remote Control System. A basic SmaRT control system consists of at least one Smart wireless remote portable unit (aka handheld), a base unit, and the wiring harness that connects the base unit to the controlled apparatus.
SmaRT BU-2CAN 2.0 BU-2CAN Base Unit The SmaRT BU-2CAN base unit features two CAN serial ports and one RS-232 serial port. It accepts an input power operating voltage range from +9 to +36 VDC. The base unit provides a robust link with a handheld remote in congested radio environments using Channel-Hopping Direct Sequence Spread Spectrum (DSSS) wireless technology broadcasting 900 MHz @ 100 mW and 2.4 GHz @ 100 mW.
Disable the machine on which the base unit is to be attached before installation. Use the configuration diagrams supplied by Cervis, Inc. to guide you in mounting the base unit and connecting your wiring harness. Base unit mounting is left much to your discretion with the following guidelines: •...
