1Introduction
The EIO-3148 network base IO
expander device enables
comprehensive access and control
of remote opto-isolated inputs and
non-polarised outputs over an
Ethernet network. In applications
where an Ethernet network
already exists, this is a significant
cost-saver as it does away with the
requirement for cabling. Through
the CathexisVision software
control, opening and closing of
integrated relay contacts can be
incorporated into any response of
a critical event.

b. Summary
This encoder has 8 opto-isolated alarm inputs and four relay (non-polarised) outputs. The encoder is powered
by a 9 to 32 VDC power source. It sends and receives data via an Ethernet cable connected to a network.

005-20151112-75 Rev 2 February 2, 2016 Page 3
These encoders are fully integrated within the NVR software, with up to 32 EIO-3148 encoders possible per
NVR unit. Setup and operation is by means of CathexisVision software. The unit IP addresses and firmware are
manageable via the CathexisVision Encoder Utility.
c. Alarm Inputs
Each EIO-3148 encoder has 8 opto-isolated alarm inputs that may be used to trigger automated system
responses.
A relay is an electrical switch that opens and closes under the control of another electrical circuit.
CathexisVision can treat the switching of these states as an Event action, and reacts with multiple possible
event actions.
The input is a signal indicating to the system that a change has taken place and requires a response.
Each input has two terminals that can be closed by means of the switch.
Examples of Alarm Inputs
Anything that can be switched can be treated as an alarm input.
Panic buttons - pressed by someone who needs help.
Passive Infrared (PIR) sensors - invisible infrared beams that cause switching when broken.
Other examples include magnetic loops, pressure pads, and door switches.
d. Relay Outputs (non-polarised)
Each EIO-3148 encoder has four non-polarised relay outputs, which may be used to switch wired utilities such
as door relays, lights alarms, etc.
A relay is an electrical switch that opens and closes under the control of another electrical circuit. In the case
of the EIO-3148, the opening and closing of the relays is controlled by CathexisVision in two possible ways:
1. Manually by an operator (e.g. manually switch on the facility floodlights when investigating an alarm),
or;
2. Automatically, as an event action in response to an event trigger (e.g. switch on a passageway light
when there is movement in the passageway).
Note:You need to connect a voltage source in series with your output device and the relay contacts. Devices
usually require an independent electrical source.
Examples of Relay Outputs
•Sirens and buzzers.
•Indicator lamps.
•Solenoid door locks –used a lot by receptionists, who can look at Live camera display of a door, and
then open the door from the CathexisVision user interface.
•Lights.
•Audio recordings –for example, an audio message in response to someone pressing a buzzer after
hours.
•Almost any electrical device.

005-20151112-75 Rev 2 February 2, 2016 Page 4
You could connect a relay output to an alarm input, and configure the input as an event trigger to trigger
multiple Event actions. In this way you would have a manual means of triggering automated CathexisVision
Event actions.
e. Opto-isolator
To protect the internal devices from external voltage spikes and harmful signals an opto-isolator is used to
separate the external current from the internal electronics.
It uses a short optical transmission path to transfer a signal between elements of a circuit, typically a
transmitter and a receiver, while keeping them electrically isolated —since the signal goes from an electrical
signal to an optical signal back to an electrical signal, electrical contact along the path is broken.
A schematic of an extremely simple opto-isolator device. The dashed line in the centre represents the isolation barrier,
over which no electrical contact can be permitted.
f. Hardware requirements
Power Sourcing Equipment
9 to 32 VDC source (ensure power cables are correctly connected example + to
+, - to -).
Full duplex switch
A switch that can handle a duplex communication system that is composed of
two connected devices that can communicate with one another in both
directions.
Single or multiple Cathexis
NVRs.
This will vary depending on your site.
Category 6 Ethernet Cable
(recommended)
Commonly referred to as “Cat-6”, this is a cable standard for Gigabit Ethernet
and other network protocols that is backward compatible with the Category
5/5e and Category 3 cable standards. Cat-6 features more rigorous
specifications for crosstalk and system noise. The cable standard provides
performance of up to 250 MHz and is suitable for 10BASE-T / 100BASE-TX and
1000BASE-T (Gigabit Ethernet). Category 6 cables can be identified by the
printing on the side of the cable sheath.
g. Physical requirements
1. For mounting consideration, the EIO-3148 is relatively small, light and robust, with dimensions
145x107x28 (w x l x h) mm.
2. If the EIO-3148 encoder is installed outdoors, it should be placed in a 3rd party enclosure because it is not
weatherproof.
3. The encoder is not designed for mobile applications, so it should be subjected to no more than transitory
shock during transportation.
4. For mounting, it has flanges.

005-20151112-75 Rev 2 February 2, 2016 Page 5
h. Software requirements
Each Encoder / IP camera requires an IP Address on the network. This can be assigned by means of the
Encoder Setup Utility .
CathexisVision 2016. While this device is backward compatible with pre-CathexisVision 2016 systems, it
will only function as an EIO-1148 on the 2016 system.
i. Network requirements
The network topology must be thoroughly understood, and the effects of the encoders on network
performance well considered before any decisions are taken on installing encoders.
j. Connector Layout and LEDs
Power LED
Connection Status LED
Micro USB connection, for debugging
USB connection for future use
DC Power Input
Ethernet, network and POE input
Reset Button
Front and Back Panel Layout
The connections on the front, and back, panel of the EIO-3148 are as such:

005-20151112-75 Rev 2 February 2, 2016 Page 6
LEDs
There are two LEDs on the EIO-3148.
Red LED: While the unit is booting the red led will flash on for 2s, then off for 0.5s. Once the unit is booted,
and the software is running, the red LED stays on.
Green LED: the green led will flash on 1s and off 1s while the software is running.

2Encoder Setup
Before you can add your EIO to CathexisVision you need to be able to find it. Each unit has its own IP address
which identifies it on the network. The EIO will also need to have the right firmware. These setups can be done
via the CatEncoder Setup Utility. This is a separate application, which is installed when you install
CathexisVision.
The CathexisVision Encoder IP Utility has a number of features, which are useful in setting up your EIO:
1. Automatically searches the local physical network (behind firewall and/or router) and lists all
CatEncoders on the network.
2. Indicates connection status for each CatEncoder.
3. Automatically lists all CatEncoders on the local network.
4. Displays Format (NTSC or PAL, where applicable).
5. Displays the IP address of each CatEncoder.
6. Displays the local Gateway IP address for each CatEncoder.
7. Displays the subnet of each CatEncoder.
8. Displays each CatEncoder’s MAC address, and whether it is valid.
9. Displays each CatEncoder’s Firmware version.
10. Displays each CatEncoder’s current Temperature.
11. Displays the current task being performed by each CatEncoder.
12. Displays messages per CatEncoder (e.g. “connected”, “20% completed”, “failed”).
13. Displays alarm messages per CatEncoder (e.g. connection “Missing”, connection “Lost”, “MAC
Invalid”).
14. Multiple IP Address assignment from the interface, without the need to power-cycle CatEncoders.
15. Multiple firmware-updates from the interface, without the need to power-cycle.
The core features that will be used here are Setting the unit’s IP address, and upgrading the firmware, if
necessary.
a. The CatEncoderSetup Interface
Run the utility; after a few seconds you will see the interface with a list of all CatEncoders that it recognises:
Icons
A green icon indicates a functional connection.
The connection status is derived from the utility
polling (pinging) the network.
When it receives no response from an encoder, it
displays a yellow icon for that encoder for 30
seconds, until the next ping. If still no response, it
displays a red icon for 30 seconds, until the next
ping. If still no response, it drops the encoder from
the list.
You can also manually poll / ping / refresh (right-
click > Refresh).
A yellow icon indicates that the connection is
missing.
Under the alarm column, you will simultaneously
see the word “missing”.
A red icon indicates that the connection is lost.
Under the alarm column, you will simultaneously
see the word “Lost”.

3CathexisVision Setup
To setup an EIO-3148 in the CathexisVision software follow these steps.
Note: This unit is designed to work with CathexisVision 2016 and onwards. On earlier software versions it will
function as an EIO-1148, and will be setup as such.
a. Open the Network I/O Setup
First Open Your Site
File Open Site site_Name
Then Open the Setup Tab for that Site
Site Open Tab Setup
Open the Network I/O Setup
File Your_Site_Name Open Tab Setup Server 
.
b. Add/Edit an EIO-3148
To Add/Edit an EIO-3128 click on one of the options at the base of
the Network I/O panel.
After clicking on New/Edit the setup dialogue will open. There are two tabs, the Settings tab and the I/O tab.
Settings Tab
Select the relevant Type from the drop-down menu.
Give the unit a descriptive name.
Fill in the IP address which was assigned via the Encoder setup utility
(see the previous section).
Fill in the login details. (default username = admin, default password =
admin).

005-20151112-75 Rev 2 February 2, 2016 Page 12
I/O Tab
The I/O tab is where the user may
define certain aspects of the Inputs
and Outputs.
Inputs
The inputs may be
enabled/disabled, as well as
named.
Outputs
The outputs may be
enabled/disabled, and named.
The user may also control an
output from this panel with the
following options:
The user may also set the output’s
pulse duration.
c. Default Input State Setup
The input states are high when the device is connected. When disconnected the input states show as
Unknown; CathexisVision sees this unknown state as low by default. If you have an event set up using one of
the EIO3148's inputs to trigger when its state is low, the event will trigger when the device is connected again,
as the state goes from low back to high. To resolve this, do the following:
Enable Debug Mode and Enter Advanced Setup
Note: This must be done on the server (this cannot be done from a client)
1. Once on a server, enter the Setup Tab, and press SHIFT+ALT+d.
2. Navigate to the Configure Servers section. (Make sure to do this after taking the first step.)
3. Expand the Advanced section.
Once you have entered the advanced section select the Inputs option. In the Inputs Panel
to the right, Right-click the inputs in question

005-20151112-75 Rev 2 February 2, 2016 Page 13
Either change the Set state when unknown option to high;
or select the Use last known state when unknown.
