USING THE TRANSMITTER
The transmitter logic is independent of the receiver except in
thefollowingways:
1.
2.
Self Test
Parity Option
In self test the transmitter outputs route to the receiver inputs
internallyandtheTXD0andTXD1outputsareinhibited.
When parity is enabled, both the receiver and transmitter are
affected. Odd parity is automatically generated in the 32nd
bitifthisoptionisselected.
This output goes high for 1 transmitter error and 3 receiver
errors. To determine which error is being flagged, read the
Status Register. Reading the Status Register also clears the
error flag. The transmitter will not function until the error is
cleared. ItcanalsobeclearedbyMRgoinghigh.

TXD0 will go high during a transmission if the data is zero.
TXD1 goes high if data is a one. When both pins are low this
is referred to as the Null state.

CablingNoise
The HI-6010 has TTL compatible inputs and therefore
they are susceptible to noise near ground. If the data bus
is passed by ribbon cable or the equivalent to the device
under test, it is possible to get significant glitches on the
