Licensees that formerly or currently offer separate sale decoders include Train America Studios, Digital Dynamics, and Electric RR Co. TMCC decoders have mostly been installed in 3-rail O gauge models, but it has also been offered in 2-rail O scale and S scale. TMCC utilizes the same command codes as Digital Command Control (DCC).
A block transfer protocol allows several bus transfers to occur with a single address cycle. In block transfer mode, the first transfer includes an address cycle and subsequent transfers require only data cycles. The slave is responsible for ensuring that these transfers use successive addresses. Bus masters can release the bus in two ways.
ARINC 429, [1] the "Mark 33 Digital Information Transfer System (DITS)," is the ARINC technical standard for the predominant avionics data bus used on most higher-end commercial and transport aircraft. [2] It defines the physical and electrical interfaces of a two-wire data bus and a data protocol to support an aircraft's avionics local area ...
The scales used include the general European modelling range of Z, N, TT, H0, 0 and also the large model engineering gauges of I to X, including 3 + 1 ⁄ 2, 5, 7 + 1 ⁄ 4 and 10 + 1 ⁄ 4-inch gauge. As 00 is a particularly British scale, it is not included within this pan-European standard. However the predominantly US imperial-based S scale ...
The S-100 bus or Altair bus, IEEE 696-1983 (inactive-withdrawn), is an early computer bus designed in 1974 as a part of the Altair 8800. The S-100 bus was the first industry standard expansion bus for the microcomputer industry. S-100 computers, consisting of processor and peripheral cards, were produced by a number of manufacturers.

There may also be one or more Bus Monitors (BM); however, Bus Monitors are specifically not allowed to take part in data transfers, and are only used to capture or record data for analysis, etc. In redundant bus implementations, several data buses are used to provide more than one data path, i.e. dual redundant data bus, tri-redundant data bus ...
An exponentiator may be needed at the end of a series of analog computation stages done in a logarithmic scale in order to return the voltage scale back to a linear output scale. Additionally, signals that were companded by a log amplifier may later be expanded by an exponentiator to return to their original scale.
