1.5 Symbols and notations
The symbol "DANGER" means an imminent danger. If it is not avoided, can result in death or serious
injury.
"DANGER" is used to warn of dangers at the time of the warning are already existing (e.g., hot sur-
faces, sharp edges, pinch points, etc.).
It is used exclusively in danger of personal injury!

2SAFETY INSTRUCTIONS
This chapter is for your safety and the safety of equipment operators. Please read this chapter care-
fully before working with a VPN-Router.
General safety
•Personnel which install, program, operate or maintain this device must have read and understood
these instructions.
•The personnel must be thoroughly familiar with all warnings, instructions and requirements con-
tained in this manual.
•The applicable local safety, protection and installation requirements must be observed.
•The user is solely responsible for selecting the correct product and the technical design in accord-
ance with appropriate local regulations.
ESD component
Observe precautions for handling electro sensitive devices!
2.1 Qualified persons
wienet VPN router must be installed by competent persons only, configured in operation, commis-
sioned and maintained. Qualified is, who:
•has an appropriate technical training and
•has access to the wienet VPN router installation manuals, and this has been read and under-
stood.

2.2 Intended Use
Please, observe the following instructions:
•The router must be used in compliance with all applicable international and national laws and
in compliance with any special restrictions regulating the utilization of the router in prescribed
applications and environments.
•To prevent possible injury to health and damage to appliances and to ensure that all the rele-
vant provisions have been complied with, use only the original accessories. Unauthorized modi-
fications or utilization of accessories that have not been approved may result in damage to the
router and in a breach of applicable regulations. Unauthorized modifications or utilization of
accessories that have not been approved may result in the termination of the validity of the
guarantee.
•The router cannot be opened.
•Turn off the router and disconnect it from power supply before handling the SIM card.
•Caution! The SIM card could be swallowed by small children.
•Input voltage must not exceed 36 V DC max..
•Do not expose the router to extreme ambient conditions. Protect the router against dust, mois-
ture and high temperature.
•The router should not be used at petrol stations. We remind the users of the duty to observe the
restrictions concerning the utilization of radio devices at petrol stations, in chemical plants, or
in the course of blasting works in which explosives are used.
•Switch off the router when travelling by plane. Utilization of the router in a plane may endanger
the operation of the plane or interfere with the mobile telephone network, and may be unlaw-
ful. Failure to observe these instructions may result in the suspension or cancellation of tele-
phone services for the respective client, or, it may result in legal sanctions; it may also result in
both eventualities.
•When using the router in the close proximity of personal medical devices, such as cardiac pace-
makers or hearing aids, you must proceed with heightened caution.
•If it is in the proximity of TV sets, radio receivers and personal computers, the telephone may
cause interference.
•It is recommended that you should create an appropriate copy or backup of all the important
settings that are stored in the memory of the device.
For any other use, or changes to the equipment – even in the context of mounting and installation –
any warranty claim against Wieland Electric GmbH expires.
2.3 Expansion port safety
•The expansion port must be used in compliance with all applicable international and national
laws and in compliance with any special restrictions regulating the utilization of the communi-
cation mod-ule in prescribed applications and environments.
•Use only the original Wieland accessories. Thus, you will prevent possible health risks and dam-
age to the devices and ensure compliance with all relevant provisions. Unauthorized adjust-
ments or use of unapproved accessories may result in damage to the expansion port and breach
of applicable laws. Use of unapproved adjustments or accessories may lead to cancellation of
guarantee, which has no effects on your legal rights.
•Do not expose the expansion port to extreme conditions. Protect it from dust, moisture and
heat.

3CNT EXPANSION PORT
3.1 Description
The user interface CNT is for monitoring and processing analogue and binary signals and for control-
ling (settings) of binary signals. There are 2 counter and 2 binary inputs or 4 binary inputs, 2 ana-
logue inputs and 1 binary output available. The settings of binaries and counter inputs by the help of
firmware in which the single input and output is defined. Binary output is off by default configura-
tion (is not switched to ground).
At expansion port CNT including in modem, it is possible to use power supply management. At per-
manent idleness the expansion port CNT is switch to low power supply mode when demand current
is very low (100 μA). Switch time to this status is program adjustable. The module wake up is possi-
ble by PORT status variation.
3.2 Input and output description
3.2.1 Analog input
On analogy input it detected current, converted to digital 12-bits value and modified by multiplica-
tive and additive constant. Next the value is averaged on user settings and stored to PC memory.
The basic range of input current is 0 – 20 mA at input resistance 100 Ohm.
Equal of value is:
((12b value + addit. constant) * multiplic. constant)/1000
The sample period on analogy inputs is adjustable in range 0 ÷ 65535 seconds. At value 0 it is sam-
pling once per second and measurement circuit is permanent switch on. At sampling it is possible to
set time of measurement circuit switch from 16 ms to 375 ms.
On the basis of signal change about bigger value then setting upper/lower limit is generated alarm.
The alarm end is on the basis of bigger/lower signal change about set hysteresis than is upper/lower
limit.
3.2.2 Binary input
The binary input is potential-free contact which is 8x per second sampling and sampling time is
1/64 seconds. For binary inputs it is possible to set active level to either log. 0 or log. 1. Choosing ac-
tive level can generate an alarm.
3.2.3 Counter input
The counter inputs are meters maximal to 100 Hz. The ratio impulses on input can be maximal 1:10,
that means the impulse width must not be lower than 1/10 signal period. At lower width the true
evaluation of the metered signal is not guaranteed. For metering of small frequencies (about MHz) it
is important to set the multiplicative constant which multiplies metering frequency (flow) because
of true evaluation.
On the basis of signal change about bigger value then setting frequency upper limit is generated
alarm. Alarm is possible send after time after which upper limit must be overrun.
In case that it isn't any change on input, it is possible to define time after which the value on input
will zero.

3.2.4 Binary output
The binary output is realized by a transistor with open collector. In inactive state (log. 0) the transis-
tor no transfer and is as switch off. In active state (log. 1) is transistor switch on and connect signal
on ground (GND).
Maximal switching current on output is 100 mA. Maximal voltage which can be on transistor collec-
tor is power supply voltage of the router.
The impulse length is possible to set in a range of 125 ÷ 8000 ms which is possible to send on output
after impulses number setting (1 ÷ 65535) on input BIN1/CNT1.
In sleep mode the all input and output values are metered and controlled.
3.3 Selecting the current of binary output
If active level is set as log. 1, electric current can be selected with jumper. When jumper J4 (see fig-
ure) is mounted on pins, electric current value is 20 mA. When jumper J4 is not mounted, electric
value is 8 μA. If current value is 20 mA, CNT has higher consumption, also it has higher resistance to
industrial noise.

3.5 Description of protocol XC-CNT MODBUS ASCII Slave
The XC-CNT MODBUS ASCII slave protocol is a communication protocol by means of which the
router communicates with the CNT board. Using this protocol, the station configures board soft-
ware, reads the buffer, controls binary output and switches the main station supply off.
The expansion port CNT communicates by this protocol with bit rate 9600 bit/s (8N1).
