DMXDart Operation

•

Double ended data loss testing – checks a cable for its’ data transmission

stability by connecting both ends to the DMXDart’s DMX input and output and
transmitting 250Kbps data over it.

•

Single ended loopback data loss testing – same as double ended data

loss testing, but it allows for testing of permanently installed cable through the
use of a loopback connector.

During this test the DMXDart counts packets of data that have been transmitted
and received. If the DMXDart detects data corruption on either of the pairs, an
Err! Will appear beside the problem pair. (2-3) Denotes pins 2 and 3 of the DMX
cable, or pair #1, and (4-5) pins 4 and 5 – pair #2.
The error message is held until CLR is pressed to reset the test.
