described above until the display changes – once it does, you’ve found
the button.
In network ID number setup mode, you first set the “units digit” of the ID
number, then you set the “tens digit”. If, for example, you want to set a
network ID number of
01 , the units digit is 1 and the tens digit is 0 .
When enter network ID number setup mode, the display will change to
Un-0
, and the number will start counting up from 0 to 9 . When it gets to
9 , it will start again at 0 . This is the units digit, and to set the units digit,
you must press the hidden button when the digit you want is being
displayed.
If you want to set the ClassNet Terminal to network ID number 01 , press
the hidden button when the display shows
Un-1
.
Once you’ve set the units digit, the tens digit will start counting up from 0
to 9 . When it gets to 9 , it will start again at 0 . To set the tens digit, press
the hidden button when the digit you want is being displayed.
If you want to set the ClassNet Terminal to network ID number 01 , press
the hidden button when the display shows
Un01
.
The ClassNet Terminal will then display the whole network ID number for
a short time, and it will sound a beep to signal that the network ID number
has been set.
If you make a mistake while setting the network ID number, you should
continue setting it, then start the procedure again – there’s no way to go
back or make a correction while you’re in network ID number setup mode.
Note that you can’t set the network ID number to 00 , and setting the
network ID number to 99 will erase and re-format storage memory, and set
the network ID number to 01 .
RS-485 Network Cabling
The ASP ClassNet Terminal and Intelligent RS-485 Adaptors are
designed to use the “CAT5” type cable commonly used with Ethernet
computer networks. These use RJ-45 connectors, and you can buy CAT5
cables off-the-shelf in many places, in lengths from 0.5 to 20 metres or
sometimes longer. Alternatively, you or your cabling contractor can
custom-make CAT5 cables to suit your requirements. Note that CAT5
cables are used for convenience of installation only, and you CANNOT
connect a ClassNet Terminal into an Ethernet network.
Care must be taken with the routing of the cable when it is installed. The
ideal situation is for the network cable to be kept as far away from other
cabling (ie mains power, telephone, alarm, RF, etc) as possible. Where
possible, the network cable should cross other cables at a right-angle.
