General:
Before using this unit, read this manual completely and gather all information on
the unit. Make sure that you understand it fully. Check that your application does
not exceed the safe operating specifications for this unit.
Before installation, maintenance or modification work:
Prevent damage to internal electronics from electrostatic discharges (ESD)
by discharging your body to a grounding point (e.g. use of wrist strap).
Prevent access to hazardous voltages by disconnecting the unit from DC
power supply and all other electrical connections.
Installation:
This unit should only be installed by qualified personnel.
This unit should only be installed in a “restricted access area”, for example a
lockable cabinet where access is restricted to service personnel only.
This unit is intended for permanent connection to the DC power supply.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the DC power supply. Ensure compliance to
national installation regulations.
Units with the rated voltage up to 42.4 V peak or 60 VDC, are defined as class III
equipment and shall be separated from hazardous voltage by double or reinforced
insulation.
This unit uses convection cooling. To avoid obstructing the air flow around the unit,
follow the spacing recommendations (see Installation section on page 13).
The TD-29 is designed to be used on dedicated lines and is not
approved to European standard CTR-15 (2-wire leased line).
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.

Description
The TD-29 is designed for communication on 2-wire copper cable (twisted pair).
Multidrop or point to point is possible.The TD-29 will support half duplex at baud rates
up to 19.2 kbit/s.
The TD-29 is easy to configure for different operating conditions with DIP-switches.
Character formats, baud rate, transmission level, DCD detection level and communication
interface are selectable. DTE-equipment can be connected through an RS-232 or
an RS-422/485 interface.The RS-232 connection can be made through either the DB-9
connector or screw terminal on the front of the unit.There are four baud rate settings.
When using the RS-232 interface the direction of communication can be controlled by
RTS handshake signal or incoming data.
When connecting in multidrop configuration the maximum bus length depends on the
number of units connected. (see below)
