  • Low Profile PCI Express 8-Port

    7803e - Sealevel Systems, Inc.

    The 7803e low-profile PCI Express serial interface provides eight RS-232 serial ports. For maximum compatibility with a wide range of peripherals, the board supports all standard RS-232 modem control signals. The serial ports utilize 16C954 UARTs with 128-byte Tx/Rx FIFOs that enables data rates to 921.6K bps for reliable high-speed communications in data-intensive applications. This high-performance UART includes 9-bit framing support and is fully software compatible with legacy 16550 applications. In addition, the board derives a 62.5 MHz clock from the PCI Express link. This ultra-high speed clock is divided by a flexible 8-bit clock prescalar with 1/8 steps to provide support for the widest range of standard and non-standard baud rates.

  • SMS Data Logger

    Ajinkya Electronic Systems

    To alert a user when process parameter exceeds the limits is an important function of a data logger. The IM2000 series normally provides alarm relay outputs and the user can have common relay for all channels or can have individual relays for each channel. These channels can be grouped as well. Apart from the user, the other concerned persons in the plant should know that there is an alarm. SMS Data Logger / GPRS Data Logger generate a text alarm message as soon as the alarm condition is observed. SMS technology can be used to send periodical process updates as well. It can be used to send data to remote PC connected to GSM Modem. Information can be transferred with the help of GPRS technology as well. Thus the field conditions can be monitored any where in the world at any given point of time.
