According to:
TIA-968-A and CS-03 Part 1, issue 9
This equipment complies with Part 68 of the FCC rules and the requirements adopted by the ACTA.
On the left side of this equipment is a label that contains, among other information, a product
identifier in the format US:AAAEQ##TXXXX. If requested, this number must be provided to the
telephone company.
A plug and jack used to connect this equipment to the premises wiring and telephone network must
comply with the applicable FCC Part 68 rules and requirements adopted by the ACTA. A compliant
telephone cord and modular plug is provided with this product. It is designed to be connected to a
compatible modular jack that is also compliant. See installation instructions for details.
Caution-to reduce the risk of fire, use only No.26 AWG or lager telecommunication cable.
The USOC jack required RJ11-C, and the REN is used to determine the number of devices that
may be connected to a telephone line. Excessive RENs on a telephone line may result in the
devices not ringing in response to an incoming call. In most but not all areas, the sum of RENs
should not exceed five (5.0). To be certain of the number of devices that may be connected to a
line, as determined by the total RENs, contact the local telephone company. For products approved
after July 23, 2001, the REN for this product is part of the product identifier that has the format
US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point
(e.g., 03 is a REN of 0.3). For earlier products, the REN is separately shown on the label.
If this equipment TD-36/485 causes harm to the telephone network, the telephone company will
notify you in advance that temporary discontinuance of service may be required. But if advance
notice isn't practical, the telephone company will notify the customer as soon as possible. Also, you
will be advised of your right to file a complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations or procedures that
could affect the operation of the equipment. If this happens the telephone company will provide
advance notice in order for you to make necessary modifications to maintain uninterrupted service.

Electrical Safety Advisory:
Parties responsible for equipment requiring AC power should consider including an advisory notice
in their customer information suggesting the customer use a surge arrestor. Telephone companies
report that electrical surges, typically lightning transients, are very destructive to customer terminal
equipment connected to AC power sources. This has been identified as a major nationwide problem.

Description
The TD-36 (485) is designed to function reliably within industrial environments and in
areas of high level interference.
The TD-36 (485) is a V.34 modem meaning that it can support bidirectional data rates of
up to 33.6 kbit/s on the PSTN or leased line side. Fast connect ensures that leased lines
can re-establish connections in the range of 5 seconds.
The modem is equipped with transient protection on the line side and a “watchdog”
that monitors and automatically resets the modem in the event of a fault. These functions together with remote configuration make the modem perfect for installation at
unmanned sites and prevent the need of costly service trips.
The modem also has password protection, dial-back security and caller ID answering to
ensure that only authorised users can communicate with the modem and any connected
equipment.
The TD-36 (485) also has a single digital input and output relay. The input and output can
be used to trigger, or be triggered by a number of different user defined events. Both the
digital input and output are galvanically isolated from the rest of the modem.
For ease of setup the modem is supported by the Westermo TD-tool configuration software but also has DIP switches to assist configuration. Drivers for Windows setup are
also supplied.

6618-2202
Generic I/O
The generic I/O gives the following functionality:
1. Establishing a data connection to a predefined target number
When the input is pulsed, the modem establishes a data connection to the stored
predefined number. After a time (specified in the modem) without data exchange,
the connection is released by an inactivity timer.
2. Sending an SMS Message to a predefined targetnumber
When the input is pulsed, the modem will send an SMS to a predefined number.
The SMS Messages can handle at least 160 characters. TAP and UCP protocols are
supported.
3. Sending a Text Message to a predefined targetnumber
When the input is triggered, the modem will establish a connection to the stored
modem number and transfer a predefined text message. This is not an SMS message.
4. Using the remote digital output
When the input is triggered, the modem will establish a connection to the stored
number of a remote TD-36 and send out a command, that pulses the remote output
according to a predefined sequence.
5. Executing an AT-Command string
Pre-programmed AT command strings stored in the modem can be executed.
These can (for example) be used for switching DTE communication parameters for
online and offline modes by using two entries.
6. Transparent I/O
When the input is triggered, the modem will establish a connection to the stored
number of a remote TD-36 and send out a command, and after a connection is
established, the I/O is bi-directional.
11
6618-2202
Digital Output
The digital output gives the following functionality:
1. Output Contact
The modem has a change over relay output (SPDT-contact). This output can be
controlled by a remote modem through Transparent I/O and Output service in the
Generic I/O function. The output can also be programmed to follow the local DCD
or DTR signals.
2. Remotely controlled
The output can be programmed to follow a remote modem data input. A remote unit
can also set/reset the output as well as transferring a sequence of “set- and resets” of
the output.
3. Follow DCD/Network
The output can be programmable to follow the local DCD or DTR signal.
Digital Input
The digital input gives the following functionality:
1. Static input
A static digital level trigged input high or low triggers the Generic I/O. With a level
trigged input only the first entry in the Generic I/O list can be trigged by the I/O input.
The input is trigged when the selected level has been stable for ta ms. A new trig will not
occur until the input has return to the opposite state an back again.

2. Pulsed Input
When input is set to edge trigged pulsed the number of pulses counted selects the entry
to be trigged.
For the pulsing of an input, some timings must be kept.
The input is filtered and pulses shorter than ta is discriminated. The time between pulses
must also be kept shorter than Tp. One other restriction on Tp is that Tp ≥ 2ta.
When time between pulses exceeds Tp the number of pulses are accumulated and an
entry selected by number of pulses counted.
The parameter ta is also used when output pulsing is selected.
The parameters ta and Tp are programmable from 10 ms to 2550 ms.

For a cable located within 3 m and connected to this port, the use of shielded cable is recommended, this is
to minimise the risk of interference. The cable shield should be properly connected (360°) to an earthing point
within 1 m of this port. This earthing point should have a low impedance connection to the conductive enclosure of the apparatus cabinet, or similar, where the unit is built-in. This conductive enclosure should be connected to the earthing system of an installation and may be directly connected to the protective earth.
