Interfaces

• Serial
  • RS-232 (DB-9M)
  • RS-232PH (DB-9M); power harvesting version
  • RS-485 (6-position wire terminal block) - Switch selectable between RS-422 half duplex, RS-422 full duplex and RS-485
  • Sensor (RJ-45)
• USB
  • USB 2.0 Full Speed (with ESD protection); connects to host via captive 2-meter cable

Environmental

• XBee 232, 485, Sensor, USB, Analog I/O and Digital I/O
  • Operating temperature: -40° C to 70° C
  • Powering options
    • Battery: -18° C to 55° C
    • External power: 0° C to 40° C
    • External power (hardened): -35° C to 74° C
• XBee 232PH
  • Operating temperature: 0° C to 65° C

Power Requirements

• XBee 232, 485, Sensor, Analog I/O and Digital I/O
  • Externally powered: 9-30 VDC, locking connector
  • Battery powered: 3 internal N cell batteries
• XBee USB
  • Bus powered: +5V from USB bus
  • Power consumption during normal operation:
    • XBee: 70 mA
    • XBee-PRO: 70 mA (Rx) and 250 mA (Tx)
  • Power consumption during suspend mode:
    • XBee and XBee-PRO: 200 uA
• XBee 232PH
  • Internal battery provides power when unit is operating and recharges from the serial port when in sleep mode
  • Requires a sleep/wake duty cycle as part of its normal operation.
  • Requires a fully functional serial port conforming to the RS-232C standard for optimal operation.
  • Sleep/wake duty cycle requirements will vary based on the current output of serial port
  • Serial ports with more than 14VDC output (rare) are not supported and may cause malfunction
  • Serial ports that provide hard power of 5 to 14VDC on one or more pins will allow the device to operate continually without a sleep/wake cycle
