each device and assign it a number based on the
device’s serial number. The lowest serial number
will be given the lowest device number. The next
lowest serial number will be given the 2nd lowest
device number and so on until all devices have a
number. This ‘plug and play’ system is selected by
choosing the auto option on the external device
(if it is available).
The connection of external devices to the serial
bus is done with phone cable with modular plugs.
These are 6P4C plugs (sometimes called RJ12).
These loop through each device, either using
the two sockets on the device or using a double
adaptor for single socket devices.
8.4 Troubleshooting
If a current measuring device does not appear
in the external list of devices then check the
following things:
a. If the device address selection is set to manual,
check that two devices are not assigned to the
same address number.
b. Check the cabling to the device. If the cable
has a plug on it that is the wrong way round, then
it will not communicate.
c. The discovery process can take a few minutes
if a new device is added while the system is
running.
