INSTRUCTIONS FOR INSTALLATION AND USE
SBC485-3
Before using this module, please read this instruction booklet carefully in order to ensure maximum performance and safety.
INSTALLATION
The SBC485 should operate at an ambient temperature between 0 and 50°C, do not install the unit closet to heat sources. To reduce
the effects of electromagnetic disturbance, keep the unit and the signal cables well separate from the power conductors.
Connect the SBC485 to the PC with a standard RS232 cable, and setup the RS485 network by following these instructions: ensure a
linear cable run and minimise the length of the extensions (max. 2 metres), avoid star-connections (see wiring diagram); use screened
cable and terminate the line with a 120ohm resistor. The RS485 connection is polarised, respect the indications "A" and "B" on each
connected peripheral.
OPERATION
The SBC485 module uses TX and RX signals of the RS232, the other signals are not used.
The 4 LED's on the box side give indications on the operation status and data flux. The left-hand LED (green) shows data flux coming
from the PC, the second LED (red) shows the activation of the RS485 driver with consequent line engagement, the third LED (yellow)
shows the flux received and sent to the PC, the fourth LED (green) is switched on when the SBC485 is powered.
