Descripción detallada

El SC105 dispone de buffer interno que guarda datos temporalmente. Esto permite al datalogger y al dispositivo DCE, funcionar a distintas velocidades, almacenando los datos recibidos del dispositivo más rápido hasta que el dispositivo más lento está listo para recibirlos. El buffer asegura también que no se pierdan datos durante la transmisión.

Conexiones cable y elementos fijación

Se entregan tres cables con el SC105 (13657 Null Modem Cable, SC12 CS I/O Data Cable, y 10873 Serial Data Cable). El cable 13657 sirve para programar el SC105 mediante ordenador. El SC12 conecta el SC105 al datalogger, y el cable 10873 conecta el SC105 al puerto RS-232 DCE del dispositivo. El cable SC12R-6 (que se puede adquirir por separado) se puede utilizar en lugar del SC12 si se requiere más distancia.

El kit de montaje 16987 permite fijar el SC105 en la placa de montaje de nuestros armarios intemperie.

Consideraciones Datalogger

Note: When using an SC105 with OS version 4 or newer with a mixed-array datalogger, the datalogger operating system should be updated to the latest released version

  1. The SC105 uses the RS-232 standard, which is not compatible with multidrop communications (more than two devices on the same RS-232 bus). There are some third-party devices on the market that allow multiple devices to communicate over the same RS-232 link.

  2. Depending on what equipment is being used, a special interface may be required to attach a specific device to the datalogger’s CS I/O port. In general, devices with a CS I/O port can be attached directly to the datalogger’s CS I/O port. Devices with an RS-232 port require a special interface, such as the SC932A or SC105, to connect to the datalogger’s CS I/O port.

  3. Both the computer’s serial port and the SC105’s RS-232 port are configured as data terminal equipment (DTE) devices. Because both components are DTE, a null modem cable is needed between them.

  4. The SC105 needs to be connected to the datalogger’s CS I/O port, either directly or with the included SC12 cable. The SC105’s RS-232 port needs to be connected to the PC’s serial port using the included null modem cable.

  5. Using an SC105 with a RavenXTV or RavenXTG cellular modem allows for the two devices to communicate at differing baud rates. It also allows for other devices, such as an RF401 radio or CR1000KD handheld display, to simultaneously be connected to the datalogger’s CS I/O port.

  6. The SC932A only is compatible with modem-enabled (ME) two-way communication between a datalogger and a modem. In contrast, the SC105 is compatible with both ME and Synchronous Device for Communication (SDC) communications, as well as having the ability to internally buffer data.

  7. Most third-party modems require a null modem cable, SC105, SC110 cable, or SC932A to interface with a datalogger.  Many modems manufactured by Campbell Scientific can connect directly to a datalogger’s CS I/O port using an SC12 or serial cable.

  8. An RS-232 device cannot be directly connected to the CS I/O port of the data logger. A peripheral, such as an SC932A or SC105, is required.
