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.
