It decodes the received RF signals into the transponder's identification number, checks the validity and handles the conversion to a standard serial interface protocol.
The Series 2000 Control Module is the interface between the TI-RFid Radio Frequency Module RI-RFM-104B, RI-RFM-007B or RI-RM-008B and the Host. It decodes the received RF signals into the transponder's identification number, checks the validity and handles the conversion to a standard serial interface protocol. In addition, it can store up to 909 reading transactions into the buffer. It is offered with two different serial interfaces, the RI-CTL-MB2A for point-to-point communicaton via RS232 and the RI-CTL-MB6A for point-to multipoint communication via RS422/485 interface. It has two open collector outputs and eight configurable digital input/outpuits that can be defined by the user.
CME8000-BUS: The CME8000 is a BiCMOS integrated straight through receiver with very high sensitivity and a pre-decoding of the time signal transmitted from WWVB, DCF77, JJY40, JJY60, MSF and HBG. The receiver is prepared for multi-frequency and country reception by using an integrated logic. It is connected to an on-board micro-controller in the CME-BUS which is programmed with a pre-defined serial interface protocol. The module can then act as a tap into a inter-processor serial communications bus, and is able to communicate between two or more boards, micro controllers or other devices distributed among one or more this module, any host can always through its interface obtain absolute proofed time information.
The SDI-12 communication standard, a kind of serial data communication interface protocol, is widely used in environment monitoring in Euro-American countries.
Digital communication The instrument offers an optional RS485 2/4 wire/ RS232 serial interface with MODBUS RTU protocol for access to instrument parameters.
Sometimes SPI is called a four-wire serial bus, contrasting with three-, two-, and one-wire serial buses. The SPI may be accurately described as a synchronous serial interface, but it is different from the Synchronous Serial Interface (SSI) protocol, which is also a four-wire synchronous serial communication protocol.
Digital communication  The instrument offers an optional RS485 2/4 wire/ RS232 serial interface with MODBUS RTU protocol for access to instrument parameters, or the option Profibus DP (slave).
These include: a 10 bit analog to digital converter, a low power analog comparator with the ability to generate an external voltage reference, Up to three serial interfaces depending on which protocol is used, 5 general purpose 16 bit timers, a Real time Clock with calendar and alarm function, 32 bit multiplier, direct memory access for low power peripheral operation, and up to 33 IO pins that are all capable of generating an interrupt.
