Safety Instructions

When working with Serial Piggybacks follow the instructions below and read the manual
carefully to protect yourself and Serial Piggybacks from damage.

The device is a built-in component. It is essential to ensure that the device is mounted in a way
that cannot lead to endangering or injury of persons or damage to objects.

In case of damages to the device, which might affect safety, appropriate and immediate
measures must be taken, that exclude an endangerment of persons and domestic animals and
property.

Current circuits which are connected to the device have to be sufficiently protected against
hazardous voltage (SELV according to EN 60950-1).

The Serial Piggybacks may only be driven by power supply current circuits, that are contact
protected. A power supply, that provides a safety extra-low voltage (SELV or PELV)
according to EN 60950-1, complies with this conditions.

The Serial Piggybacks have to be securely installed before commissioning.

Protect the Serial Piggybacks from dust, moisture and steam.

Protect the Serial Piggybacks from shocks and vibrations.

The Serial Piggybacks may become warm during normal use. Always allow adequate
ventilation around the Serial Piggybacks and use care when handling.

Do not operate the Serial Piggybacks adjacent to heat sources and do not expose it to
unnecessary thermal radiation. Ensure an ambient temperature as specified in the technical
data.
DANGER
Hazardous Voltage - Risk of electric shock due to unintentional contact with
uninsulated live parts with high voltages inside of the system into which the Serial
Piggybacks is to be integratred.

All current circuits which are connected to the device have to be sufficiently
protected against hazardous voltage (SELV according to EN 60950-1).
NOTICE
Electrostatic discharges may cause damage to electronic components.


To avoid this, please discharge the static electricity from your body before you
touch the Serial Piggybacks.
Furthermore, you should prevent your clothes from touching the Serial
Piggybacks, because your clothes might be electrostatically charged as well.

1. Overview
TheserialpiggybacksRS-422Adapter,RS-485Adapter,RS422-AdapterInternalTerminationandTTY
Adapter areadd-on PCBs which carry the drivers and transceivers forserial interfaces. Theydefine the
interface between the serial controller and the peripheral bus.
The pin assignment and the dimensions of the piggybacks are designed to fit in a special plug socket
that enables the user to realize a RS-422, RS-485, TTY or, using a RS-232 driver like e.g. the MAX232
a RS-232 interface.
The following figure shows the arrangement of the piggybacks and the RS-232 transceiver at the plug
sockets.
Figure 1: Plug-in socket dimensions and piggyback/RS-232 driver arrangement
Please read the manual of the carrier board for the resulting pin assignment of the serial interface
connector (e.g. DSUB9) at the carrier board.
The plug sockets have to be able to carry pins with a diameter of 0.5 mm.

4. TTY Piggyback
The TTY-Adapter is available in two versions:
- TTY-Adapter passive, see chapter “Schematic Diagram of TTY-Adapter passive”
- TTY-Adapter active, see chapter “Schematic Diagram of TTY-Adapter active”
4.1 Schematic Diagram TTY-Adapter passive
Figure 7: Schematic diagrams of the TTY-Adapter passive
The TTY piggyback is configured as a passive interface in default state (V.1930.06).
4.2 Schematic Diagram TTY-Adapter active
Figure 8: Schematic diagrams of the TTY-Adapter active
In the ‘TTY-Adapter active’ version (V.1930.08) the pins X2, X3 and X4 of the TTY-Adapter are
connected (-12 V). This can be done by a simple wire bridge at the top layer of the piggyback, because
the threepin are close to eachother. The TTYactive mode can onlybe used if the carrierboard supports
the necessary supply voltage of ±12 V.
