"Z voltage is too low on receive"
Description
The lowest voltage on the Z 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 Z 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.
"Minimum Y voltage is too high on receive"
Description
The lowest voltage on the Y line must be below 2.5 volts during receive
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 such as 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 and Z voltages do not overlap on receive"
Description
The lowest voltage on the Y line must not be higher than the highest voltage on the Z
line and The lowest voltage on the Z line must not be higher than the highest voltage
on the Y line during receive.
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
