voltage on the Y line (delta y) must be within 25% of the difference between the
maximum voltage on the Z line and the minimum voltage on the Z line (delta z)
during receive. That is, delta y must not be 25% greater than delta z and delta z must
not be 25% greater than delta y.
Possible Cause
This problem can be caused by a faulty network driver in the selected network
device, or by a problem in the network wiring. To verify if this problem is due to a
faulty network driver, disconnect all network wires from your control system and
attach the selected device directly to the control system using a short length of
network wire and repeat the test. If you receive this message again, you have a
problem with your network device. If not, there is a problem in your network wiring.

"Y voltalge is too high on receive"

Description
The highest voltage on the Y line must not exceed 6.88 volts during receive.
Possible Cause
This problem can be caused by a faulty network driver in the selected network
device, by a short circuit between the Y line and power in the network wiring, or by
a break in the ground line. To verify if this problem is due to a faulty network driver,
disconnect all network wires from your control system and attach the selected device
directly to the control system using a short length of network wire and repeat the test.
If you receive this message again, you have a problem with your network device. If
not, there is a problem in your network wiring.

"Z voltage is too high on receive"

Description
The highest voltage on the Z line must not exceed 6.88 volts during receive.
Possible Cause
This problem can be caused by a faulty network driver in the selected network
device, by a short circuit between the Z line and power in the network wiring, or by a
break in the ground line. To verify if this problem is due to a faulty network driver,
disconnect all network wires from your control system and attach the selected device
directly to the control system using a short length of network wire and repeat the test.
If you receive this message again, you have a problem with your network device. If
not, there is a problem in your network wiring.

"Y voltage is too low on receive"

Description
The lowest voltage on the Y line must be greater than -1.25 volts during receive.
Possible Cause
This problem can be caused by a faulty network driver in the selected network
device or by a short circuit between the Y line and ground in the network wiring. To
verify if this problem is due to a faulty network driver, disconnect all network wires
from your control system and attach the selected device directly to the control system
using a short length of network wire and repeat the test. If you receive this message
again, you have a problem with your network device. If not, there is a probable short
circuit in your network wiring.
