Description technique

The LS300G is a cellular gateway (also commonly referred to as a cell/cellular modem). It is locally and remotely manageable using Sierra Wireless's ACEManager™ web interface or AT and AToIP commands.

Please note the power requirements for this device. The LS300G draws significantly more current than the RavenXTG. In many cases, a station that leaves the LS300G on continuously will require at least a 50W solar panel and an 84 Ah battery (10 days of battery reserve). As such, most users will attach the power input of the LS300G to the SW12 port on the data logger or to a power relay controlled by the data logger.


  • Carrier Approval: AT&T
  • Network: 3G HSPA+ with fallback to GSM/GPRS/EDGE
  • Dimensions: 76 mm x 90 mm x 25 mm (3.0 in. x 3.5 in. x 1.0 in.)
  • Weight: 190 g (6.7 oz)

Host Interfaces

  • 10/100 Base-T RJ45 Ethernet
  • RS-232 serial port, DB9 Female

The LS300G will connect to any of our devices that have an RS-232 serial or Ethernet port. 

  • When connecting the LS300G to an RS-232 DCE device such as the CR1000, use the 18663 Null Modem Cable.
  • When connecting to the CS I/O port of a data logger, use the SC105.

When using the LS300G as a replacement for the RavenXTG, ensure that your station's power supply and recharge are adequate to handle the increased power consumption when active.

Nombre de FAQ au sujet de(s) LS300G: 1

  1. When connecting a cellular modem to any device via the RS-232 serial port, consider the baud rate required by the device that is being attached. For example, when connecting a cellular modem to either a CR200(X) using a 18663 or to a CR10(X) using a SC932A, the RS-232 baud rate of the cellular modem should be fixed at 9600. For these devices, 9600 baud is the default baud rate.
