5.3.4
RS485 Communication
The RS485 standard permits a balanced transmission line to be shared in a party line or multidrop mode. As
many as 32 driver/receiver pairs can share a multidrop network the following system illustration samples
show a typical two-wire shielded multidrop network. Note that the transmission line is terminated on both
extreme ends of the line and not at drop points in the middle of the line.
Termination is used to match impedance of a node to the impedance of the transmission line being used.
When impedance is mismatched, the transmitted signal is not completely absorbed by the load and a
portion is reflected back into the transmission line. If the source, transmission line and load impedance are
equal these reflections are eliminated.
To attain this with the IsoBase Extended System, both extreme ends of an RS485 communication network
should be terminated with a 120 ¼ watt resistor. Do not combine/mix this communication line with the
any other, including any IsoBase to PC link. They are totally independent from each other, the
IsoHub/IsoOut RS485 network is used by the IsoBase for remote measurement readout and control of the
connected IsoHub/IsoOut units. The IsoBase to PC RS485 network is use by a PC-Host for remote
measurements readout from the connected IsoBase units.
The maximum length of the RS485 should not exceed 1200Mtrs. Recommended cable types:
IsoBase RS485:
<1200m Twisted-par shielded AWG24 (0,205 mm2)
IsoHub RS485/24VDC:


The illustrated example shows the correct connection of a system where the IsoBase unit needs to
be installed in the middle of an installed multidrop IsoHub/IsoOut network. In this case it is placed
in-between the IsoHub 1 and IsoHub 2, followed by IsoOut 1.

“Rt” Stands for termination resistor, which is used to eliminate signal reflection on a RS485
multidrop network. This type of network most be terminated with a resistor of 120 in the far end
of the network.

Do not mix/combine the PC-RS485 network for IsoBase with the RS485 network assigned for the
IsoHub/IsoOut. These communication interfaces are clearly marked and should be kept separate.

As shown above, the RS485 and the 24VDC power supply to the IsoHub/IsoOut units are connected
as a multidrop bus (In the sense that the RS485 and the 24VDC power supply is coming in to a
device and leaving to the next device), no other power supply or connections should be made.

The sample above, only illustrates a system of two IsoHub and one IsoOut units. The maximum limit
is 8 IsoHub and 8 IsoOut per each IsoBase unit.

A new IsoBase system network can simply be added by connecting the new system to the same
network marked as Main RS485 in above sample.

IsoBase Menus and options
Analogue Menu
The analogue menu displayed on the IsoBase screen will always show, by default, the input with the “Highest”
current value (mA) across the network. This is also the menu to which the instrument will return if no
operations have been made within 30 seconds.
To display the value for any other input, enter the number of the required input, using the numerical keyboard
followed by the “OK” key or simply using the left and right keyboard to increase or decrease the presented
input number.
Example: To present the value of input 128, press the key “1”, “2”, “8” and then “Ok”. The newly entered input
number will be displayed replacing the current & active “Highest” or other displayed input number during the
selection. To cancel the entered input number during selection press the “C” key.
The information presented within this menu contains:
 Input number, followed by the input label.
 Current & active earth leakage values.
 Whether the input current value is the “Highest”. A filtered
earth leakage current value is indicated by “mAF“.
 The active state for the displayed input such as “Ok”,
“Warning” or “Alarm”.
 Whether the alarm memory active status has occurred, if so
the active state changes to “Alarm Memory”.
 If the IsoBase unit is not able to stabilise any communication
with the installed IsoHub/IsoOut units, the active state will
change to “IsoHub-Com Alarm”.
