The DB9 connector is used to connect both serial line and power supply. The radiomodem device can be configured using the configuration software included (if requested). For further information please refer to the in-line help. The parameters that can be changed are indicated below: FRONT VIEW FUNCTION TX RS-232 / A RS-485 RX RS-232 / B RS-485 - POWER SUPPLY / SGND RS-232 + POWER SUPPLY 6-12 VDC values from C hex to 17 hex values from 0000 hex to FFFF hex Power supply Consumption Radio channels Radio frequency Standard radio max 100 mA at 12 VDC 12 channel / 65536 codes each ISM 2.4 GHz Band IEEE 802.15.4 DSSS (direct sequenze spread spectrum) 60 (Europe only) / 100 mW da –10 °C a +40 °C 95% non condensating available RS 232 or RS 485 (optional) standard from 1200 to 115200 baud internal Emitted power Working temperature Relative umidity Serial port Baud rate Antenna the incorrect connection of the wires or the inversion of poles on the power supply may damage the apparatus exceeding the maximum power supply value (12 VDC) may damage the apparatus the apparatus must run exclusively on batteries or on a power supply protected against short circuits the connection wires must not be connected to dangerous voltages The radiomodem RX pin must be wired to the computer TX pin or vice versa. The radiomodem SGND pin must be wired to the computer SGND. RTX01 Two or more devices can exchange data correctly only if all of the parameters are the same on each device. If the PAN ID or THE CHANNEL are different, the devices are connected to different nets and they can’t exchange data. 9 + 6/12 VDC GND RS-485 WIRING EXAMPLE (optional) The radiomodem A pin must be wired to the A RS-485 line. The radiomodem B pin must be wired to the B RS-485 line. ADOS S.r.l. - Via Lazio 25 - Buccinasco (Mi)
