Basic hardware explanatory notes
We would like to explain a few terms in the beginning of this manual.
The Adash DSP board
The Adash DSP (Digital Signal Processing) board is the most important part of the instrument. The
special chip provides all necessary operations, which are required for achieving of 4 channel
synchronous data.
4-20mA current loops and its industrial use
For industrial process control instruments, analog 4–20 mA current loops are commonly used for
analog signaling, with 4 mA representing the lowest end of the range and 20 mA the highest. The key
advantages of the current loop are that the accuracy of the signal is not affected by voltage drop in the
interconnecting wiring, and that the loop can supply operating power to the device. Current loop
outputs of actual value are then used in control systems (PLC).
The current loops used in the A3716 are isolated from measuring circuits. They must be externally
powered (they use passive mode).
Relay outputs
Two relay initial states exists. Energized and de-energized. Energized relay is initially powered and its
internal connections are as seen on the picture below (NO-normally opened, NC-normally closed,
COM-common are standard electrical terms). De-energized relay is initially not powered. Internal
connections are seen on the pictures.
Latched relay
We describe it on example:
The factory initial state of the relay is de-energized (i.e. NC and COM is connected). The ISO RMS
(10-1000Hz) value is measured on the machine. When the RMS value will exceed 2 mm/s, then the
relay will switch on the red light in a control room. When the vibration value will decrease under the
2mm/s, then the relay will switch off the light.

If the LATCH function is chosen, then the relay will not switch off the light when the vibration
decreases less than 2mm/s. The relay keeps the switch ON until it is manually switched off ( through
the use of REL–RST).

B1...B8 – Isolated inputs 5-30V/4mA max. The level of voltage on each input defines the logical state.
Logical 0 - DC voltage 0-3V is required
Logical 1 - DC voltage 5-30V is required.
You should avoid the voltage in 3-5V range. The response of the circuit is unclear and unpredictable.
It may oscillate and accidentally change logical values.
REL - SYS - if the A3716 system is in correct operation then this system relay is energized (A3716/3U
only). In case of DSP board error or ICP error relay is deenergized.
REL - RST resets all latched relays (A3716/3U only).
R-: Common negative pole
R1 and R2: (DC voltage 5-30V/4mA max.)
When the voltage appears on R-R1 or R-R2 then all latched relays will be reset. You may have a
question: why two clamps are used (R1 and R2)? It enables to reset latched relays by two buttons
which could be in two places. E.g. one reset button is near of the A3716 and second reset button is in
the control room.
CH 1 – 16 AC inputs (ICP® powering available) for AC signals measurement, usually for vibration
measurements (acceleration sensor connected). Max. Peak/Peak voltage range is +/- 12 V.

A3716 IP address setting (the same for the
A3800)
A3716 rack basically behaves as a local PC and it has its own IP address under which it is recognized
in your network. Most common situation is that you will need to change the A3716 rack IP address
because of your company’s policy.
Remark: If you don’t need to change the rack IP address, skip to chapter: Network for data transfer
There are two ways how the setup the IP address.
A3716 (A3800) as a stand alone computer
Windows OS is installed on A3716 measurement unit, so it is possible to connect with it like to a
common PC. Connect USB keyboard, mouse and monitor (VGA interface or HDMI interface). In
Windows login as a "remote" user with "remote" password and follow the chapter IP address setting.

Network remote access
Second option how to change the A3716 IP address is to do it through network. Use the LAN cable
and connect the A3716 unit with PC (laptop) directly or through network (switch/HUB). IP address (set
during production) is written on the A3716 front panel. Use this IP address for remote desktop
connection. You can also use name of the unit, which is „A3716 – serial number“.
Remote desktop connection
Remote desktop connection is a program which allows to control another PC on the network from
your PC. From any PC on the network you can connect A3716 and change its setting (e.g. IP
address). Remote desktop program is a standard part of the Windows OS. You can find it under Start
button in Accessories folder.
It can be run also by "Search programs and files" in Start menu (Win7). Enter "mstsc" and press enter.
You can launch it also from "Run" window (press Win + R). Enter "mstsc" and press Enter.
New window Remote desktop connection appears then.
Enter the IP address or name of the computer into the Computer line and press Connect. Enter log in
parameters (factory settings are remote for username and password).

Network for data transfer (the same for the
A3800)
Server ( computer ):
- Determined for data collection and storage
- Ideally stand alone computer which is not used for any other purposes
- Continuous operation – pay attention on a proper components selection
- Connect ideally Gbit network with A3716 with DDS computer
- Suitable size of RAM and HDD
Software on a Server:
- Windows OS on the server
- DDS for tree management / data collection
- Program Data Manager as a service which handles data
Company network usage
In case of using company network, you need to assign static IP addresses to all components
(measuring units, server, users stations). We recommend to do it in cooperation with IT department.
Creating of your own network
If you decide to build your own computer network, then follow the following procedure. We always
recommend to create a network with cables, not wireless.
