X-10 protocol for the Marmitek XM10 OEM Controller
applied (in envelope form) to the controller. This output is coincident with the second X-10 transmission.
(X-10 codes are always transmitted in groups of two, except for Bright and Dim.)
Data sent to the controller is valid X-10 data. The start Code (1110) can be used to alert the controller that
an X-10 Code will follow. A .1. bit from the two-way interface appears as a negative going pulse 1.1 ms
long, beginning approximately 100 µs after zero crossing. The controller should sample this data between
500 and 700 µs after zero crossing.
The L.E.D. on the two-way interface gives a visual indication that X-10 codes are being received. The
L.E.D. is illuminated when AC power is applied to the two-way interface and blinks off when X-10 codes
are received. The two-way interface will also receive the codes it transmits, therefore the L.E.D. will also
give an indication of codes being transmitted.
The ability to read X-10 codes from its own output also allows the controller to incorporate data collision
detection. If the code received differs from the code transmitted, the code can be assumed to have been
corrupted by noise ( or another transmission ) on the power line.
The line Monitor capability of the two-way interface allows the controller to ensure that the power line is
free from X-10 signals before starting a transmission. This means that in a multitransmitter system the
controller can minimise contention between transmitters. For example, if after detecting that the line is
free, a transmitter waits for a random number of power line half cycles before transmitting, the chance of
collision is reduced. A different priority can be assigned to each transmitter by including a fixed delay
before the random delay. The shorter the fixed delay, the higher the priority.
Important Safety Notice
Zero volts in this product is directly connected to one side of the AC line.
Therefore, for safety, an ISOLATING power transformer MUST be used when attempting any internal
measurements.
The power supply in the two-way interface are capacitively derived from, and directly referenced to, the
230V AC power line. Care should be taken when monitoring any internal circuitry with an oscilloscope, as
the OV reference in the two-way interface are NOT isolated from 230 volts.
X-10 Protocol
The tables in Figure 1, show the Binary Codes to be transmitted for each House. Code and Key Code.
The Start Code is Always 1110 which is a unique code and is the only code which does not follow the
truecomplement relationship on alternate half cycles.
