Before installation:
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.
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.
This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Cooling section).
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from power supply
and all other electrical connections.
Warning! Do not open connected unit. Hazardous voltage may occur within this
unit when connected to power supply or TNV circuits.
Care recommendations
Follow the care recommendations below to maintain full operation of unit and to
fulfil the warranty obligations.
This unit must not be operating with removed covers or lids.
Do not attempt to disassemble the unit. There are no user serviceable parts inside.
Do not drop, knock or shake the unit, rough handling above the specification may cause
damage to internal circuit boards.
Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.
Do not paint the unit. Paint can clog the unit and prevent proper operation.
Do not expose the unit to any kind of liquids (rain, beverages, etc). The unit is not water-
proof. Keep the unit within the specified humidity levels.
Do not use or store the unit in dusty, dirty areas, connectors as well as other mechanical
part may be damaged.
If the unit is not working properly, contact the place of purchase, nearest Westermo dis-
tributor office or Westermo Tech support.
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.

This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a industrial installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
… Reorient or relocate the receiving antenna
… Increase the separation between the equipment and receiver
… Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected
… Consult the dealer or an experienced radio/TV technician for help.

Description
The TR-36B is a rack mount analogue V.34 PSTN and 2- or 4-wire leased line modem.
It supports data rates of up to 115.2 kbit/s on the terminal side and modem modulation
speeds of up to 33.6 kbit/s on the line side. The modem is designed to harsh industrial
standards for applications where a number of modems are required in the same location. The unit has passed extensive approvals testing by both Westermo and external test
houses, showing the modem can operate in environments with a high level of electromagnetic interference.
The TR-36B features a number of security functions such as password protection, dialback security and caller ID answering making the modem ideal for critical industrial applications. The TR-36B can also be remotely configured making it ideal for use in unmanned
installations.
The modem is designed to be prepared for unexpected faults. The modem is equipped
with transient protection on the line side and a watchdog function that monitors and
automatically resets the modem in the event of a fault. In case of a leased line failure, a
PSTN dial backup facility can be configured for additional reliability.
The TR-36 is configurable via its serial interface using standard terminal emulation software using Hayes AT commands or the Westermo TD-Tool modem configuration utility.
Additionally many functions of the TR-36B can be configured via the onboard
DIP-switches.
The modem is designed for use in the Westermo RV-07B 19" rack, which can hold up to
16 cards as well as two PS-20 power supplies. The modems slide into the chassis from
the front with all line connections terminating onto the backplane. The rack can hold up
to 16 TR-36B modems and can also be externally powered by a 24 V supply.

Termination recommandations of Leased lines
and Dial-up connections
In some connections the communication line (Leased Line or PSTN) must be
terminated. The table below shows the right way to activate the termination
for different usages. As a standard, the receiver in multidrop systems at the end
points shall be terminated.

RS-422/485 general advice
Termination recommendations
4-wire termination
2-wire termination
The RS-422/485 line must be terminated. In the TR-36B, the termination is combined
with fail-safe functionality. The termination is used to prevent undefined states when the
bus is in tri-state condition.
… Using 2-wire RS-485 both ends should be terminated.
… Using 4-wire RS-485 both pairs shall be terminated at both ends.
… Using 4-wire RS-422 it’s only necessary to terminate the receivers.
RS-422/485 connection pins can be differently named. For some equipment brands
the T+ corresponds to A, but other brands might use some other naming convention.
If a unit does not work it can help to swap A and B.

Mounting /Removal
Before mounting or removing the unit:
Make sure that the RV-07B modem rack
has been installed according to
instructions.
Mounting
The TR-36 is designed to fit
into the RV-07B rack. The
modem is installed by sliding
the card along the slot guides.
Ensure the card is the correct way up, the handle will be at
the
bottom of the card. Press firmly but carefully until full connection between the modems
32 pin male connector and the connector on the backplane is achieved.
To ensure proper galvanic connection between front panels, do not leave empty slots
between modems. Always add modems from one side in the rac
