DEI 1016 ARINC 429 Transceiver

The DEI 1016 provides an interface between a standard avionics type serial digital data bus and a 16-bit-wide digital data bus. The interface circuit consists of a single channel transmitter with an 8X32 bit buffer, two inde- pendent receive channels, and a host programmable control register to select operating options. The two re- ceiver channels operate identically, each providing a direct electrical interface to an ARINC data bus. The transmitter circuit contains an 8 word by 32 bit buffer memory and control logic which allows the host to write a block of data into the transmitter. The block of data is transmitted automatically by enabling the trans- mitter with no further attention by the host computer. Data is transmitted in TTL format on the D0(A)/D0(B) out- put pins. The signal format is compatible with DEI’s extensive line of ARINC 429 Line drivers for easy connec- tion to the ARINC data bus.
