Switch16/ om3 Hardware Manual • Doc. No.: A.1109.21 / Rev. 1.1 Page 7 of 31

Overview
1. Overview
This manual describes the standard version Switch16/ om3 and the customized version
Switch16/ om3-F together as Switch16/ om3, differences will be noted. The Switch16/ om3 and
the Switch16/ om3-F use the same hardware. They only differ in the configuration of the serial
interface OM-A at the delivery.
1.1 Description
Figure 1: onnection diagram
The Switch16/ om3 operates as a managed Ethernet switch with an integrated OM server.
It comes with 16 Ethernet ports via RJ45 sockets and 3 serial interfaces via DSUB9 connectors.
All interfaces are easily accessible via connectors in the front panel.
A Texas Instruments SitataTM microprocessor, which is based on the ARM® ortex®-A8 processor,
is equipped on the Switch16/ om3. It is used as OM server for the serial interfaces. Furthermore,
the PU is responsible for the switch management. It is connected via an additional internal
Ethernet port.
The Switch16/ om3 provides 3 serial interfaces in the network, that can be accessed for example
from a P . The serial interfaces of the OM ports can be switched per software between the
standards RS-232, RS-422 and RS-485.
A switchable 24V/1A power supply for external devices is incorporated in the serial interface
OM-A. It can be enabled via an internal jumper and switched on and off by software.
The Switch16/ om3 supports web-based network management for statistics, monitoring, VLAN
(Virtual Local Area Network) etc. The usage of the VLAN improves the security and flexibility of the
network because the sub-networks are logically separated from each other.
The OM server supports driver software for Windows® 7 and Windows 10 (32 and 64 bit).
To configure the serial interfaces on the host P the Switch16/ om3 comes with an easy-to-use
Windows based tool. For the configuration of the Switch16/ om3 features via the integrated web
interface a standard web browser can be used.
A microSDTM card connector is easily accessible from outside. It can be used for firmware updates.
ustomized options are available for customized series production in reasonable quantities.
Please contact our sales team for detailed information.
For example for AN-Ethernet-Gateway applications an optional AN interface can be equipped.

4.4 Reset Buttons
The Switch16/ om3 comes with two buttons for the reset of the factory defaults and the customer
default. The buttons are equipped on the P B. They are accessible via two little holes in the side
panel, see Figure 6, page 12. Use a non-conductive pointed object (e.g. a screw-driver) with up to
1.5 mm cross section.
Reset Button Labe Description
Factory
Reset A F-RST
A factory reset can be made when the Switch16/ om3 is switched
on (power-on). Therefore carefully push and hold the button A (F-
RST, see Figure 6 page 12) by means of the pointed object during
power-on until the Status LEDs of the OM interfaces OM-A and
OM-B are flashing.
After the factory reset the Switch16/ om3 restarts automatically with
the factory defaults.
ustomer
Default B -DFLT
It is possible to create a file with a customer default configuration of
the Switch16/ om3 with the esd-Netintegrator (see software
manual). The file can also be downloaded via the esd-Netintegrator.
The Switch16/ om3 can be reset to the customer default values
during power-on. Therefore carefully push and hold the button B ( -
DFLT, see Figure 6 page 12) by means of the pointed object during
power-on until the Status LEDs of the OM interfaces OM-A and
OM- are flashing. All settings are reset to the values contained in
the customer default configuration file.
If the button is pushed and there is no file selected, the settings will
not be changed. The Error LED starts flashing to indicate the failure
of this action.
After the customer default values are set, the Switch16/ om3
restarts automatically with the customer default values.
4.5 Configuration COM-A / 24V (Jumper JP1900)
The Switch16/ om3 comes with jumper JP1900, which is equipped on the P B top layer inside of
the housing.
Standard (Switch16/Com3 - A.1109.01):
On delivery jumper (JP1900) is set in this standard version in a way that the Ring Indicator / TS
signal is available on interface OM-A. The OM-A interface can be configured as RS-232, RS-
422 or RS-485 interface per software.
See Switch16/ om3 software manual [1] for further information.
Customi ed (Switch16/Com3-F - K.0508.74):
On delivery jumper (JP1900) is set in this customized version in a way that the fused 24V output is

Hardware Insta ation
Procedure:
1. Demount the module as described in chapter: “4.2 Demounting”.
NOTICE
E ectrostatic discharges may cause damage to e ectronic components.
→
→
To avoid this, please discharge the static electricity from your body before you touch
the Switch16/ om3.
Furthermore, you should prevent your clothes from touching the Switch16/ om3,
because your clothes might be electrostatically charged as well.
2. The jumper is inside the case of the Switch16/ om3.
Figure 9: Side/Bottom view (screws) Figure 10: Side/Top view (screws)
Loosen the six screws in the Switch16/ om3 case: Three in the bottom panel (Figure 3) and
three in the upper panel (Figure 4); use Torx T6 screw driver.
From Rev. 1.1: Loosen two additional screws in the front panel.
3. Open the case of the Switch16/ om3.
Figure 11: Switch16/ om3 P B ( ase open)
4. The jumper is equipped on the P B top layer (see Figure 11).
5. onfigure the jumper JP1900 according to your needs.
