Wiring Examples for Data Cable
A flashing LED indicates a pair A LED that does not glow
with a wiring fault indicates an open pair
Quick Test: The LEDs for all four pairs glow
TEST
indicating a properly wired cable.
1-2
LOW BATT
(coax)
Notes: The T568A wiring standard is the same as
3-6
X
SHORT
T568B, except that T568A swaps the green and
4-5
orange pairs. Either standard will test the same
MISWIRE
electrically, as long as the same standard is used
7-8

S
SPLIT
All four pairs cross over (transmit to receive
TEST
and receive to transmit).
1-2
LOW BATT
(coax)
3-6 Quick Test: The LEDs for all four pairs glow
X
SHORT
and the "X" LED illuminates indicating a properly
4-5
MISWIRE
wired cross over cable.
7-8
REVERSAL
S
SPLIT
There is a split between the pairs on
TEST
pins 3-4 and 5-6. Continuity is correct,
1-2
but the split can cause a high level of
LOW BATT
(coax)
crosstalk between the pairs.
3-6
X
SHORT
4-5
Quick Test: The SPLIT LED glows and the LEDs
MISWIRE
for pairs 3-6 and 5-6 flash indicating the split is
7-8
REVERSAL
between these two pairs.
S
SPLIT
The pair on pins 1 and 2 is shorted and the
TEST
pair on pins 7 and 8 is open.
1-2
LOW BATT
(coax)
3-6
Quick Test: The LED for pair 1-2 flashes and the
X
SHORT
SHORT LED glows indicating the pair is shorted.
4-5
MISWIRE
The LED for pair 7-8 does not glow indicating
the pair is open.
7-8
REVERSAL
S
SPLIT
The pair on pins 1 and 2 is reversed and the
TEST
wires on pins 5 and 6 are crossed at one end
1-2
of the cable.
LOW BATT
(coax)
3-6
X
SHORT
Quick Test: The LEDs for pairs 1-2, 3-6 and 4-5
4-5
flash to indicate a wiring error. The MISWIRE
MISWIRE
and REVERSAL LEDs glow to indicate the type
7-8
REVERSAL
of errors.
