Installation procedure
SPECTRE Module Access - SMA
Frequency Band: 865 - 868 MHz
Frequency Band: 902 - 928 MHz
Use an AC/DC power supply LPS type, Limited Power Source (as per IEC EN 60950-1 Ed2) or ES1 type, PS1 (as per IEC EN 62368-1) for main supply and for
an eventual V+/V-.
Main power supply:
Range +9 Vdc up to +36 Vdc
Consumption:
Typical: 1A under +12 Vdc
Communication:
RS485 (L+ & L-) / RS232 (TD & RD)
Pin out:
Removable connectors 3x4 pins and 1x8 pins, thread 3.81 mm / 0.149 in
Temperature:
-25 to +60 °C / -13 to +140 °F
Protection:
IP66 level
Chip:
EPC1 Gen2 (ISO 18000-63) - 1 to 62 bytes max
I/O:
4 optocoupled inputs and 4 optocoupled outputs
Module LED:
1 red LED: presence of power supply and 1 green LED: activity on Reader / host link
Antenna LED:
7 configurable colors (red, green, blue, orange, purple, turquoise, white)
Use a multi-conductor shielded twisted pair cable.
Max length RS485:
3 280.84 ft / 1000 m at 9600 baud.
Max length RS232:
49.21 ft / 15 m.
▪ Install the module/reader away from computer transmission cables or from power sources (ex: RJ45, sector...).
The disruptions that they can cause can vary according to their radiation power and their proximity.
▪ Use a filtered and regulated power supply.
▪ Antennas connected to different modules/readers may interfere with each other. Move them away from each other.
▪ A power supply which provides 1.5 A min under +12Vdc is recommended.
If the IN/OUT are powered by the module, use a 2A min under +12Vdc power supply.
▪ Users must not remain within a range of less than, 34 cm / 13.39 in from an antenna for an extended period of time as per EN50364 applicable to this
type of device.
▪ Apart from the hatch the module housings must not be opened.
▪ Before any service operation you must de-energize reader.
▪ Check that the hatch seal is correctly positioned before closing.
▪ Do not remove the caps of unused
cable glands:
▪ Careful: There is a 5.5 volts DC on each RF port.
In order to access the module/reader connectors, open
the hatch.
