TMO-100
Functions and Features
The TMO-100 is a radio data communication modem for TETRA networks. These
modems allow transparent data communication between two or more nodes in a TETRA
network. The TMO-100 conveniently combines the functions of a controller, router,
modem, and radio transceiver in a single compact enclosure.
The TMO-100 supports standard serial and IP-based data communication protocols. It
has two serial data interfaces (RS-232 or RS-485/422) and an Ethernet (10/100
Mbits/sec) port. For TETRA radio networking, either of two modes can be selected:
SDS based communication or packet data transmission.
An optional voice communication feature is also available, by which field personnel can
talk with a control room.
The TMO-100 can also be optionally provided with built-in inputs and outputs that can
be read and set remotely using the MODBUS-RTU protocol. It is possible to transmit
information about an input change automatically to another station as soon as an alarm
condition occurs ["unsolicited message"].
The TMO-100 has a rugged aluminum housing compatible with standard DIN rail
mounting. The wide power input voltage range of 12-24 VDC [+/- 20%] makes it easy
to integrate the unit into monitoring and control systems.

Connections and Hardware Installation
2.1
Mechanical Details
The dimensions of the TMO-100 housing conform to DIN 43880, and therefore it can
be mounted on a standard 35mm DIN rail [DIN EN 50022]. Two serial interfaces are
provided for connecting the TMO-100 to a PC/PLC or other local terminal equipment.
The main serial interface ("COM") uses a standard 9-pin D-sub connector, while the
secondary serial interface ("AUX") uses a standard RJ-11 socket. On the lower side of
the housing an RJ-45 connector for the Ethernet port allows the TMO-100 to be hardwire networked with local terminal equipment or PLC’s. On the upper side of unit
another RJ-45 connector is provided for connecting a voice handset, for speech
communication over the TETRA network.
On the upper side of the unit is located the plug-in terminal connector for the power
supply (12-24 VDC +/-20%) and a BNC socket for the antenna.
A 10-pole DIP-switch allows quick changes to the unit's settings: e.g., changeover to
Programming Mode.
LED lamps on the front panel provide information about the operating condition of the
unit: e.g., received TETRA RF signal strength, error conditions, etc.

Serial Interfaces
The TMO-100 has two serial data interfaces. The primary interface (COM) has a 9-pin
D-sub connector on the upper side of the unit. The secondary interface [AUX] has an
RJ-11 socket on the lower side of the unit. The COM interface can be either RS-232 or
user-selectable RS-422/485. The AUX interface can be RS-232 or RS-485 (only).
The following parameters are user adjustable: baud rate in the range 1200 - 57600 bps,
data word length 7 or 8 bits, odd / even / no parity, and 1 or 2 stop bits. The factory
setting is 9600 bps, 8 data bits, no parity, 1 stop bit.
If a frame error is detected, or if the parity bit does not conform to the setting, the
received data block is rejected.
Both serial interfaces are supplied as RS-232, unless ordered otherwise. The primary
interface is optionally available as a user-selectable RS-485 / RS-422 port, while the
AUX interface is optionally available as an RS-485 port. Note that the RS-485 / RS-422
interface does not have the CTS/RTS lines.

The optional voice communication feature allows voice communication over the
TETRA network, using a PTT (push to talk) pushbutton switch and voice transceiver
(handset or headphone/microphone headset) connected to the TMO-100. When the PTT
switch is pressed, data communication is interrupted, allowing only voice
communication during this temporary period. If a gap in speech communication from
either side exists for 10 seconds, voice communication mode is terminated and data
communication restored automatically.
The voice transceiver is connected via an RJ-45 connector on the lower part of the unit.

Connecting the I/O (TMO-100/DAx types only)
Binary inputs:
The binary inputs are divided into two groups per port. Each group contains 4 inputs
with one common terminal. The inputs are bipolar, so they can be switched with an
active "+" or active "-" signal.
If the "C" terminal is connected to the ground, the inputs will be active if the positive
voltage (12-14V) applies. If the "C" terminal is connected to the positive voltage, the
inputs are activated by applying the ground connection.
Please note that the input voltage should not exceed 24V +20%!
Binary outputs:
The supply voltage for the binary outputs must be connected to the "+" and "-" terminal
of port C. Active outputs will have the positive supply switched to the related terminal.
The maximum load is 0.5A per outputs.

TMO-100
Data Communication over TETRA Networks
The TMO-100 can transfer data between any of its wired data interfaces (serial and
Ethernet ports) on one side, and the TETRA radio network on the other. The TMO-100
can handle any of the common industrial automation and instrumentation protocols
(MODBUS, MODBUS/TIP, IEC-60870-5-101, IEC-60870-5-104, PakBus, ROC,
BSAP DNP3 etc.…), custom protocols, and configuration data.
Data communication is possible in any of three modes (of which two are supported
presently):
SDS based data transfer:
With SDS based data communication, the TMO-100 can transfer data in serial data
packets of up to 1000 bytes each. The packets are broken down if necessary (transparent
to the user) into smaller SDS data blocks. Serial data communication protocols such as
MODBUS, DNP3 or IEC-60870-5-101 are smart routed to the slave modems. To do
this, the TMO-100 extracts the logical addresses, looks up a routing table, and sends the
data onward to the slave/receiving station modem with corresponding ISSI address.
The maximum length of an SDS data block is configurable up to 255 characters.
Restriction of SDS data block length is necessary because not all TETRA
infrastructures support the full length of 2047 bit. If the data block to be transferred is
longer than the maximum SDS length supported form the Tetra infrastructure, it is split
into several SDS data blocks by the transmitting TMO-100 and automatically reassembled by the receiving TMO-100.
Setting the SDS parameter
SDS based data transfer is possible only through the serial interfaces (COM or AUX) of
the TMO-100 modems. Data received from a specific (preconfigured) transmitting ISSI
address can be directed to the secondary serial interface (AUX) instead of the primary
interface (COM). This is useful, for example, where process data must be directed to the
primary serial interface, and configuration data to the secondary serial interface.
V2.62B - Page 33 of 94
Funk-Electronic Piciorgros GmbH
TMO-100
Packet-data based data transfer (option):
IP packets can be transferred if the TETRA infrastructure supports the packet data
transfer mode. In this case data communication with terminal equipment connected to
the TMO-100 is via the Ethernet interface of the TMO-100.
Here the TMO-100 functions as router. Up to 16 IP port addresses can stored in the Port
Forwarding Table of the TMO-100. Data packets arriving over the TETRA network are
automatically routed to the designated IP ports. For the reverse route a NAT function
provides the correct address for routing return data to the sending station.
Several terminal devices can be connected to the Ethernet interface of the TMO-100 via
a network switch, and addressed by any station on the same TETRA network.
Circuit switched data:
Line based data communication (CSD) is not supported by all TETRA infrastructures,
and is not at this time supported by the TMO-100.
V2.62B - Page 34 of 94
Funk-Electronic Piciorgros GmbH
3.1
TMO-100
Data Communication by SDS
Data communication by SDS does not necessarily require an IP switch within the
TETRA network: therefore it is compatible even with smaller installations. SDS Data
communication takes place only through the Control Channel (MCCH). Therefore no
additional timeslots or RF-Carriers are required for data communication. The use of a
Secondary Control Channel (SCCH) is supported by TMO-100.
The TMO-100 supports a maximum SDS length of 2047 bits (254 bytes) in accordance
with the ETSI specification. However, since not all TETRA infrastructures support this
length, users can set a lower maximum length for SDS data blocks. If the data block to
be transferred is longer than the maximum SDS length, it is split into several SDS data
blocks by the transmitting TMO-100 and automatically re-assembled by the receiving
TMO-100. This fragmentation/de fragmentation of data blocks is transparent to the
terminal equipment connected to the TMO-100 at either end, and makes the TMO-100
compatible even with older TETRA networks. In this respect, radio data communication
through TMO-100 modems behaves like wire communication, with minimum
transmission delay. If a TMO-100 receiving data detects a checksum error, the entire
data block is discarded.
SDS data communication supports data communication only via the serial interfaces:
RS-232 or RS-422/485. Transfer and routing of IP packets is not possible. In the SDS
mode of operation, the Ethernet interface can be used for configuration of the modem
by MODBUS/TCP or Web server.
The serial interface settings of TMO-100 modems on the same TETRA network do not
have to be the same. Therefore it is no problem if the master modem is set for 38400
bps, 8N1, - while the slave is set for 9600 bps, 8E1. For performance-critical
applications the serial interface should be set for the highest possible baud rate
compatible with the terminal equipment, as this naturally minimizes data
communication delay time.
V2.62B - Page 35 of 94
Funk-Electronic Piciorgros GmbH
3.1.1
TMO-100
Use of the TMO-100 as master modem
A Routing Table must be loaded into the TMO-100 when it is designated as a master
modem. Up to 1280 ISSI addresses can be registered. Each of the ISSI addresses In the
Routing Table is assigned to a logical address in sequential order, corresponding to the
addresses used by the serial data communication protocol.
The Routing table can be set up using the embedded Web-Server or by Modbus RTU
protocol.
The TMO-100 is configured (user setting) for the specific serial data communication
protocol to be used. Any of the commonly used protocols can be selected, e.g.,
MODBUS, IEC-60870 or DNP3. Customized (non-standard) protocols may also be
used because the position of the address byte and its length (1 or 2 bytes) are also userprogrammable.
Protocol Configuration
V2.62B - Page 36 of 94
Funk-Electronic Piciorgros GmbH
TMO-100
When a data block is received at the serial interface of the TMO-100, it waits for the
complete data block to be received. The data block end criterion is that no further data
byte is received after a lapse of a user-programmed time (default: 10 milliseconds). The
protocol-dependent logical address of the destination terminal equipment is extracted
from the data received via the serial interface. Using this, the ISSI address of the target
modem is looked up from the Routing Table, added to the data block, and transmitted
over the TETRA network.
If a broadcast address is reserved in the serial data communication protocol (e.g.,
MODBUS-RTU), a corresponding GISSI (Group ISSI address) included in the Routing
Table. Therefore broadcast can be supported, whereby a data block can be sent
simultaneously to several modems on the same TETRA network.
If multiple-address routing is not possible or desired, then the TMO-100 can be
configured to use a single ISSI, to which all transmitted data is addressed. The slave
modems would be part of a group: all modems of this group receive the same data. Each
terminal equipment connected to the save modems is then responsible for determining
whether a data block is intended for it or not.
It should be noted that when SDS is broadcast to a group, the SDS is sent from all base
stations on the same TETRA network. This obviously generates a higher network load
because when transmitting to an individual ISSI, the base station sends the SDS
intended only for the specific base station to which the target terminal equipment is
connected.
V2.62B - Page 37 of 94
Funk-Electronic Piciorgros GmbH
3.1.2
TMO-100
Using the TMO-100 as Slave Modem
A TMO-100 used as slave modem need not be configured for handling a specific serial
data communication protocol. Basically, the modem passes on each data record that it
receives from a master modem out through its serial interface. When this happens, it
tags the ISSI of the master modem from which data is received, so that when it gets a
response to this data record from its local terminal equipment, it sends that response
data back to the ISSI of the master modem. Because of this procedure, a slave modem
can receive data from several master modems provided that such communications from
multiple masters does not occur at the same time.
The return address refers the slave modem to the data record of the master modem. The
response data record from the local terminal equipment is always sent back to the ISSI
of the master modem from which the last communication was received. Alternatively,
the ISSI of a specific master modem can be set in the slave modem, so that all data
received from local terminal equipment is sent only to this ISSI.
3.1.2.1
Routing SDS Data to the Primary (COM) or Secondary (AUX) Interface
The TMO-100 is equipped with two serial ports, “COM” and “AUX”. For each of these
ports, a destination port can be configured and so it can be determined whether the data
is feed from the source COM or AUX to the destination COM or AUX
If the COM routing is set to AUX, data received at the COM port will be sent to the
AUX port of the destination device.
Also if the AUX routing is set to COM, data received at the AUX port will be sent to
the COM port of the destination device.
As factory default, COM is routed to COM and AUX is routed to AUX. This feature of
using two different serial ports at the same time provides the ability to use one port for
data communication and the second port for configuration or for a second protocol if
different devices (PLC and Meter or Filed bus device) are connected to the Outstation.
Another application can use two different ports of the same device from different master
units placed also on different location.
The AUX interface is restricted, as it can not be used for RS-422, only RS-232 or RS485.
V2.62B - Page 38 of 94
Funk-Electronic Piciorgros GmbH
3.1.3
TMO-100
Data Compression using the LZ77 algorithm
The TMO-100 has data compression capability and all data records received over the
serial interface are compressed before sending as SDS. At the receiving station, the data
is decompressed before moving it out. Detailed information regarding the LZ77 can be
found at:
http://de.wikipedia.org/wiki/LZ77
Data compression can improve performance when large data blocks are involved, by
reducing the data that is conveyed over the TETRA network, even if additional SDS
blocks are created (in cases where the original data block does not fit within an SDS).
If using the TMO-100 in conjunction with TRM-, RTU-, or MDP-Type Tetra units,
(these ones do not have the compression feature) compression can be disabled.

SDS and Status messages for machine to machine, for human to machine or for human
to Voice-Terminal applications.
The Hash-Command is defined as a header control sequence within two #-characters,
followed by a SDS or status information in the following way:

TMO-100
Processing MMI Commands sent by a TMO-100, Terminal,
Mobile or Dispatcher
The TMO-100 can process so called "MMI commands" (Man Machine Interface) which
were sent from another device in the TETRA network. The MMI command is basically
a text SDS, which can be sent out by another TMO-100, a handheld terminal, a mobile
or a dispatcher. With these MMI commands, outputs can be set or reset or input values,
RF field strength or other values can be queried.
The access is protected by a 4 digit PIN, which must be included in every MMI
message to the device. If the PIN does not match, the MMI command SDS will be
discarded and no commands will be processed.
By default this PIN is set to 4711, it can be changed using the webserver configuration
menu "TETRA -> SDS/Status/MMI":
Within one MMI command message, several MMI commands can be submitted. The
commands must be separated by a comma "," or a dash "-" in this case.
If the MMI string contains an error, the faulty part will be sent back with 2 additional
"?" signs added:
#M#1-4711-T2=1234
#M#2-0000-T2=1234??
All commands which appeared before this faulty part were executed, commands after
the error were not processed!

Submitting MMI commands using a TMO-100
A TMO-100 is able to directly send MMI command strings to any other TMO-100,
using a serial port in "#-command mode". It can even process MMI commands to itself.
As MMI commands to other devices were sent by SDS, the processing of incoming
SDS MMI commands must be enabled in the configuration (TETRA ->
SDS/Status/MMI) of the remote devices. If the MMI is sent to the same device, they
will be processed and answered locally.
To use or transmit the MMI commands, the assigned serial port must be set to the
operation mode "'#'-command port".
To use or transmit MMI command with a TMO-100, they always use the format:
# C issi # 1-4711-Commands
The commands are sent out to a device or group "ssi" and they are processed by all
devices which received the SDS, matching the PIN code. It must be noticed that a MMI
SDS to a group may cause lots of response SDS by the devices in the group.
Answers will be put out in the format
#C issi # 2-0000-Answer
to the same serial port. The white spaces in the text strings here are only used in the
documentation to make it more clear, they should not be used in the real MMI
commands!
Example:
To query the RF field strength and the serial number of a device, the command string
#C1234#1-4711-RF=?-SN=?
has to be sent to the serial port.
The answer from the remote machine will be like this:
#C1234#2-0000-RF=-87dBm-SN=2000

TMO-100
If the SSI matches the ISSI of the own, local device, or if the SSI is left away, the MMI
will be processed locally.
Example:
The own TMO-100 has the ISSI 2345. The MMI command
#C2345#1-4711-RF=?
will return the own RF fieldstrength of the local TMO-100 we're connected to:
#C2345#2-0000-RF=-87dBm
Alternatively the MMI command can be like:
#C#1-4711-RF=-87dBm
which will also cause the locally processed answer:
#C#2-0000-RF=-87dBm

TMO-100
Sending MMI commands by a TETRA terminal or dispatcher
MMI commands can also be sent to the TMO-100 using a terminal, mobile or
dispatcher. The command should be sent as a normal type 4 text SDS (simple
messaging or TL-4).
The command string "#M#" must be set as a prefix, the required format should be like:
#M#1-4711-Commands
As described before, "4711" ist he PIN to access the TMO-100, which can be changed
in the device configuration "TETRA -> SDS/Status/MMI". In addition to this, the MMI
access by SDS must be enabled in the same configuration area to allow the processing
of the MMI SDS.
Example:
The MMI command string
#M#1-4711-C0=1,Z=1,RF=?
sent by a terminal to the TMO-100 will cause the following actions:
•
•
•
The binary output "C0" will be set to on
The response will include the timestamp of the TMO-100
The RF field strength will be returned
The answer sent back to the terminal will be like this:
#M#2-0000-110210151027-RF=-65dBm
Important notice:
In default state the "t-timeout" in the TMO-100 is activated, which will cause all
outputs will be reset after the given time if the TMO-100 is not accessed by MMI
commands or MODBUS telegrams. If the TMO-100 should be used only for MMI
processing, the t-timeout should be disabled in the configuration (RTU features ->
Setup)!

TMO-100
Packet Data (IP) Communication
Packet data (PD) communication essentially differs from SDS data communication in
that the TETRA infrastructure must support the use of packet data. The ISSIs of the
modems must be enabled for packet data communication. Data communication takes
place not through the Control Channel (as in the case of SDS data communication) but
through normal traffic channels. Thus an active PD connection over which data is to be
transferred, affects the availability of the voice channels: this must be taken into account
at the time of network planning.
By supporting Multi-Slot Packet Data (MPSD), network data throughput can be
increased, as several slots can be combined for data transmission. This results in higher
information flow-rate than SDS based data or Single-Slot Packet Data transmission.
The main advantage of packet-data based communication in Tetra infrastructures is that
it supports protocols using IP data packets. After powered on, the TMO-100 automatically establishes a PPP link to the Tetra infrastructure. If the ISSI has been enabled
for PD communication, the Tetra infrastructure will assign a corresponding IP address
to the Modem. The TMO-100 is thereafter is IP accessible within the TETRA network.
Terminal equipment locally connected to the TMO-100 via its Ethernet interface can
then be addressed through its router function. The TMO-100 acts as an intermediary
between its Ethernet interface and the TETRA network, so to speak.
Enabling the Packet Data Option
3.4.1
IP Assignment in the TETRA Network
The TMO-100 is assigned an IP address when it establishes connection with the
TETRA infrastructure. This IP address is a part of the network administration set-up,
and is not a configuration parameter of the TMO-100.
Care should be taken if dynamic IP-addresses are assigned from the Tetra infrastructure
to the TMO-100, because once the device will be turned off and on again, it may be
possible that it receives a different IP-address. In that case a unique correlation of the
device is not possible.
V2.62B - Page 50 of 94
Funk-Electronic Piciorgros GmbH
3.4.2
TMO-100
IP Assignment for the Ethernet Interface
The IP address of the Ethernet interface of the TMO-100 is preconfigured before
delivery as 192.168.0.199 with the net mask 255.255.255.0. These settings can be
changed by the users whenever necessary.
All local terminal devices that are to transfer data over the TETRA network using the
TMO-100 as router must operate within the same IP subnet, and the IP address of the
TMO-100 must be declared in the IP configuration as the gateway for the connected
local terminal equipment. All data packets from the local terminal equipment that are
not addressed to an IP address in the same sub-net are passed through to the TETRA
network as a result of the IP configuration..
Application example:
V2.62B - Page 51 of 94
Funk-Electronic Piciorgros GmbH
3.4.3
TMO-100
Router Function of the TMO-100
The TMO-100 has separate IP addresses for the TETRA network and its Ethernet
interface. The requirement here is to convert the IP addresses of the two networks so
that local terminal equipment connected on local Ethernet of one TMO-100 can
communicate with remote participants in the TETRA network, and vice versa.
The task of the NAT-router is therefore to link the devices that are “hidden” behind the
Tetra IP-Address, to services or protocols.
3.4.3.1
Port Forwarding
Identification of the services and routing of the local terminal equipment (for which the
IP addresses on the TETRA side are unambiguously defined) is determined through the
port numbers. The Port Forwarding Table of the TMO-100 has a list of local Ethernet IP
addresses and their corresponding port numbers. Data from the TETRA network
addressed to a particular port number is forwarded to the target local terminal
equipment by looking up its IP address corresponding against that port number.
Port Forwarding Table
V2.62B - Page 52 of 94
Funk-Electronic Piciorgros GmbH
TMO-100
Example:
The IP address 192.168.0.100 corresponds to a PLC connected to the Ethernet interface
of the TMO-100. The default (factory configured) IP address of the Ethernet interface
of the TMO-100 is 192.168.0.99. The TMO-100 has the IP address 10.0.66.17 on the
TETRA network side. The PLC is addressed using the MODBUS/TCP protocol by its
port number: Port 502.
In the Port Forwarding Table of the TMO-100 the Port 502 has been assigned IP
address 192.168.0.100 (factory configuration).
With this configuration, all packets sent over the TETRA infrastructure to the IP
address 10.0.66.17, Port 502, are redirected by the TMO-100 via its Ethernet interface
to the PLC with the IP address 192.168.0.100.
The following port forwarding settings are factory programmed (before delivery) in the
TMO-100:
•
•
•
Port 502 TCP/UDP
Port 2404 TCP/UDP
Port 20000 TCP/UDP
Æ
Æ
Æ
192.168.0.100
192.168.0.101
192.168.0.102
(MODBUS-RTU)
(IEC-60870-5-104)
(DNP3)
Therefore the local terminal equipment needs only to be configured with the appropriate
IP address depending on the protocol used. The table can be reconfigured by the user as
needed.
V2.62B - Page 53 of 94
Funk-Electronic Piciorgros GmbH
3.4.3.2
TMO-100
NAT Function (Network Address Translation)
In the same way that packets from received over the TETRA network must have the IP
addresses changed by the TMO-100 before they can be forwarded to local terminal
equipment connected to its Ethernet interface, this must also be done in the reverse
direction. This is the case whenever local terminal equipment connected to the Ethernet
interface of the TMO-100 sends data to an IP address over the TETRA network.
This process needs no configuration: it is an automatic operation that is executed
whenever a local terminal device sends data to an unknown IP address.
The TMO-100 tags the local Ethernet address from which data is received and the
unknown IP address to which it is to be sent (from which a response is expected). The
expected response (of the remote device) received over the TETRA network will be
passed on automatically to the correct IP address via the Ethernet interface.
The NAT table can store up 32 entries. Entries that are not used for 60 seconds are
purged.

TMO-100
3.4.3.3 Keeping the Port Numbers when using the NAT function (KeepPort, from
Firmware Version 1.10)
Some protocols exchange information using specific port numbers. (e.g. Fieldbus
Foundation HSE). As a standard NAT function will (could) alter the port information,
these protocols could not be used.
The TMO-100 can be configured to keep the same port number as transmitted from the
source device. The following options are available:
•
Set the NAT-Function to standard operation. In this case the port numbers from
the sender will (or can) be changed to a port number available from a port
address pool (e.g. 40000)
IP-Setting in the “Keep Port Option”: 0.0.0.0
•
If it is necessary to keep the same port address as transmitted from the sending
device, this option can be chosen. Care should be taken that only one device
attached to the TMO is using that specific port number. In case a second device
would request a transmit using the same port address, the port number will be
changed by the NAT-function and a port number out of the port number pool
would be taken.
IP-Setting in the “Keep Port Option”: 255.255.255.255
•
IP- und Net Mask Settings:
The NAT Function will try to keep the port numbers for all devices that match
to the IP address and the net mask that is configured in the Keep Prot
Configuration table (see below)
Configuration of the Keep Port Option

3.4.3.4
TMO-100
NAT - Port Number Translation
Some protocols (e.g. HSE - Fieldbus Foundation) need to transmit special port number
ranges between the Master- and Slave-Devices. In that case a classic router would
translate the port numbers to the ones dedicated for the NAT function (40000 and up),
and therefore the communication between master- and slave-device would fail.
In contrast to that, the TMO-100 can be configured in various ways to support all
communication methods used between master and slave devices. The following options
are available:
•
•
•
The Source Port Numbers are translated as performed by a classic router
The Source Port Numbers will not be changed and forwarded straight. Care
should be taken if this port already is in use. In that case the router will translate
the Port Number to one available out of his NAT pool.
Only the Port Numbers of previously defined IP numbers or IP ranges will not
be changed. Also here care should be taken if this port already is in use. In that
case the router will translate the Port Number to one available out of his NAT
pool.
V2.62B - Page 56 of 94
Funk-Electronic Piciorgros GmbH
3.4.4
TMO-100
NAT - IP Address Screening
In case the TMO-100 is connected via its Ethernet port to a LAN network, a PC or
another device where a lot of IP traffic is expected, all IP packets the TMO-100 would
receive that could not be delivered to one of the attached terminals would be transferred
via the router to the Tetra network. As all this data rubbish would be transmitted via the
PPP link to the Tetra switch, an overload of that link could be the result, causing the
properly transmitted IP packets to fail or being delayed.
Due to this reason, two screening functions can be activated in the TMO-100 witch
prevent the transmission of unwanted data to the Tetra network:
•
The Source-Filter that defines a special source IP-address, address range or an
IP-subnet for data that is permitted to pass the PPP link
•
The Destination-Filter that defines a special destination IP-address, address
range or an IP-subnet for data that is permitted to pass the PPP link
Once one or both of these filter function are enabled, only IP-packets that match the
filter criteria are forwarded and fed to the Tetra network. It is strongly recommended to
set this filter especially when operating with personal computers, a huge number of
different IP-packets will be sent to the TMO-100 and (if no filter is set) forwarded to the
Tetra infrastructure.
Settings for the NAT-Filter

3.4.5
TMO-100
MTU (Maximum Transfer Unit) Size
The TMO-100 supports a maximum packet size (MTU = maximum transfer unit) of
1500 bytes. This packet size is compatible with automation applications. If a received
packet exceeds this length, or is fragmented, it is rejected.
3.4.6
Data Compression using Packet Data
TMO-100 provides the function to receive data via its serial interface, convert it to IPData, send it via Tetra-PPP (Packet-Data) to a destination device, convert it back to
serial data, and to pass it back to the serial interface.
In this case the received serial data stream automatically is compressed by the LZ77
algorithm and decompressed on the receiver side.
Routing from a serial interface to an Ethernet port or vice versa is not supported.
3.4.7
Transmission of Serial Data using Packet Data Mode
When using the TMO-100 in Packet Data mode, serial data received on the COM or
AUX interface will be sent as UDP-packets rather than sending them by SDS. The
mechanisms used for that are the same as used when transmitting in SDS mode, except
the routing table in the master unit contains IP-addresses instead of ISSI.
Likewise in SDS mode, an outstation will store the IP number of received data and
sends back any answer or any further data stream to this IP address.

Special TETRA features
3.5.1
Prefer or avoid TETRA cells
In some cases it's necessary to distribute the TMO-100 over a number of available
TETRA cells or to "lock" the TMO-100 to a given TETRA cell.
Each TETRA cell has a specific number, the "location area code" (LAC). The LAC is
unique for each TETRA base station in a network and a cell can be identified by it. The
TMO-100 prefer or avoid cells by this identification method. For this, the
Black/Whitelist feature is used.
The lists can be configured on "TETRA Æ Black/Whitelist". There are three different
types of lists, each containing up to 10 entries.
V2.62B - Page 59 of 94
Funk-Electronic Piciorgros GmbH
3.5.1.1
TMO-100
Priority cells list
Each entry of the priority cells list has two fields to configure: The LAC for the TETRA
cell and the minimum RSSI level.
Any cell must be received with at least the defined RSSI level (or better) to be taken
into account here. The list will be chosen from LAC 1 to LAC 10 with the highest
priority on LAC entry 1.
If the TMO-100 receives the specified cell with at least the configured RSSI level, it
will register to this cell regardless if there are other cells with a better field strength.
In this example, the TMO-100 will register to LAC 17 if this cell can be received with 80dBm or better. Even if LAC 15 is at -50dBm, it will stay on LAC 17.
If LAC 17 is not available or worse than -80dBm, the TMO-100 will go to LAC 21 if
this is received with at least -75dBm.
If none of these cells is available with the minimum RSSI level, the TMO-100 will
register to any other available cell.
V2.62B - Page 60 of 94
Funk-Electronic Piciorgros GmbH
3.5.1.2
TMO-100
Cell Blacklist
The Cell Blacklist can hold up to 10 entries where the LAC code of TETRA cells can
be entered.
The TMO-100 will not register to any cell included in the blacklist, as long as there are
other cells where it can to.
In the configuration above the TMO-100 will never register to LAC 10, 11 or 12 – if
there is any other cell where it can register to. If the LAC 10, 11 or 12 are the only base
stations where it can go, it will register to the best of these cells. As soon as another cell
becomes available, the TMO-100 will change to this it it's not in the blacklist – even if
the RSSI level is much worse.
V2.62B - Page 61 of 94
Funk-Electronic Piciorgros GmbH
3.5.1.3
TMO-100
Forbidden Cells List
The Forbidden Cells list is similar to the Cell Blacklist, but the difference is that the
TMO-100 will never go to any of these cells.
If the LAC 14 in this example is the only available cell, the TMO-100 will not register
to the network and remains unregistered.
Compared to the Cell Blacklist, where the TMO-100 will register to a cell on this list in
case that there are no other cells available, it will definitely ignore the LAC's listed in
the Forbidden Cells List – even if these are the only available cells.
V2.62B - Page 62 of 94
Funk-Electronic Piciorgros GmbH
3.5.1.4
TMO-100
Dynamic Blacklisting for cells without Packet Data capability
In some networks not all cells are capable of doing a packet data connection. These may
be cells where only voice traffic channels are configured in the network management, or
where the base station is unable to do packet data.
Normally the TMO-100 will relocate to a cell with a better field strength if the cell
where it's actually registered to drops below a certain reception level. Going to a cell
which does not support packet data will cause an uncontrolled loss of a packet data
connection.
In a proper configured network, a cell which is not supporting packet data, it will report
this in the SYSINFO (the flag "Advanced Link" is not set). If the Parameter "Cell
without PD blacklisting time" is set to a number of minutes, the TMO-100 will
automatically blacklist a LAC where it registers to as soon as packet data is activated on
this TMO-100 and it recognizes that the cell does not support packet data.
The dynamic blacklisting will cause the TMO-100 to change away from this cell
immediately after discovering this, looking for another cell in hope that is supports
packet data. If the next cell does also not support it, it will be also blacklisted and the
TMO-100 continues its search for a cell with packet data capabilities. The blacklisting
for a given number of minutes will prevent the TMO-100 to go back to this cell during
the given time.
The TMO-100 can hold up to 10 dynamic blacklisted LAC's simultaneously.
Important:
If a TMO-100 is installed on a fixed location and there are known cells around which
does not support packet data, it'll be good to enter these cells into the static blacklist.
This avoids cell relocations to these cells and connection breaks right from the
beginning!

Protocols
4.1
Layer one Protocols between TMO-100 and the external device,
connected via serial interface
4.1.1
Timeout Protocol
Using the “Timeout Protocol”, the TMO-100 will accept any data received via its serial
interface(s) accepting the whole character range from hex 00 to hex FF. The “Data End”
criteria in that case are just the facts, that there is no more data received over a
predefined period of time. (Factory default is set to 10 ms for 9600 bps. That reflects 10
characters in sequence).
Basically if used other baud rates, a timeout period of 10 character-times is suggested.
Using the COM interface, a timeout period between 3-1000 ms, using the AUX
interface 10-1000 ms is programmable.
4.1.2
3964R Protocol
The 3964R often is used in the „Siemens World“, connecting PLC’s to PLS’s or PLS’s
to SCADA systems. That “Layer One” protocol is fully supported by the TMO-100.
If possible, the priority settings of the device connected to the TMO-100 should be set
to “low priority”.
Character delay and handshaking can be set up using the TMO’s embedded Web Server
Settings for the Serial Port(s)

TMO-100
Serial Protocols (RS-232 or RS-485/RS-422)
When setting the TMO as a master unit, it is useful to know what communication
protocol is used. Regarding that, the TMO-100 knows, where inside the data stream the
address byte(s) is (are) located. With that knowledge, the TMO extracts this “logical
address byte” and using the predefined address translation (or routing) table, it can
convert the protocol address into the destination ISSI of the Tetra target device.
Using that technology, in comparison to GISSI (group transmission) the load of the
Tetra network can be reduced enormously.
The outstation devices do not need any routing or address translation table. As these
units usually are used as “polled devices”, they just answer to the polling request ISSI.
The following protocols are supported by the TMO-100.

Modbus RTU
As the Modbus RTU protocol can be used either for internal device access or for
communication with an external device, care should be taken when sharing out the
Modbus addresses. Under no circumstances, an external device should have the same
Modbus address as the TMO-100.
4.2.2
ROC protocol
The ROC protocol has the same basic data structure for the address byte location and
data packet detection than MODBUS, so MODBUS and ROC protocol shares the same
protocol setting in the configuration.
4.2.3
DNP3
Using the Link Address out of the DNP3 protocol, the routing to the outstation can be
calculated. In case of transmitting multiple DMP3-Data Segments while the timeout
period is not considered, each data segment will be transmitted individually.
Outstations can send data at any time to the master device (unsolicited messaging)
Serial DNP3 was tested with the TMO-100 simultaneously with the HART protocol.
The DNP3 was communicating over the COM port while HART was transferred via
AUX. In that application the TMO-100G Serial-to-Tetra Gateway was used with an
ETELM switch and Infrastructure.
4.2.4
IEC 60870-5-101
The routing for this protocol is similar to the DMP3. Also in this case it may be that
multiple data segments are sent, to complete one message.
4.2.5
PakBus
Pak bus is a much unknown protocol, but it is fully supported by the TMO-100.
4.2.6
BSAP
The TGW-100 detects the difference between the normal and the extended messages in
BSAP protocol and extracts the address information accordingly. The node address
contains 7 bit, so the address range which can be used for routing here is 0-127.
As any device can also act itself as a router, you may enable a master-to-master
communication for the used serial port.
Any node can then itself contain a routing table for a retransmission of information to
other nodes (which is not possible when acting in slave mode)

4.2.7
TMO-100
User-Protocol
Using user-defined protocols, the exact position of the address bytes and the address
length can be pre defined.
If these parameters are unknown, the “Transparent Data Communication” can be used
(see below).
4.2.8
Transparent Data Communication without Protocol Filter (User Defined)
Protocols, where the address byte can not be extracted, or where the „Address Range“
exceeds the TMO-100 storage spectrum, (1024 entries, e.g.: sometimes that can happen
using the HART protocol) can be transmitted using the Group ISSI or a fixed, predefined ISSI.
Care should be taken when using the GISSI communication, as this method increases
the over all load of Tetra networks.
In case the ISSI parameter is set to not equal zero for COM or AUX, all data will be
transmitted to that particular ISSI. In this particular case, the routing is ignored
4.2.9
Hart-Protocol
Serial HART was tested with the TMO-100 simultaneously with the DNP3 protocol.
The DNP3 was communicating over the COM port while HART was transferred data
via AUX. In that application the TMO-100G Serial-to-Tetra Gateway was used with an
ETELM switch and Infrastructure.

Remark on using HSE (Fieldbus Foundation):
As HSE FF needs to send data from the slave to the master device with an unaltered
port number and vice versa, the NAT function should be set to “Keep Port”. In this case
the source port number will not be changed by the NAT function and forwarded to the
destination device.

TMO-100
Configuring the TMO-100
5.1
Configuring the TMO-100 through the Integrated Web Server
The adjustable parameters of the TMO-100 can be configured through the integrated
Web server from a conventional browser. This can be done either over its Ethernet
interface or over the TETRA network, in packet data mode. The Web server responds to
queries through Port 80.
Example:
The TMO-100 is delivered with a factory-installed IP address 192.168.0.199 for the
Ethernet interface. A PC connected to this interface has the (for example) the IP address
192.168.0.26. To configure the TMO-100, type http//192.168.0.199 in the address
window of the browser and hit "Enter". If necessary, a fixed IP address in the range
192.168.0.xxx may need to be assigned to the connected PC.
The TMO-100 can be connected using a 1:1 patch cable if connecting to the PC via a
switch or hub. If connecting to a PC directly, use a crossed cable.
If the TMO-100 is operated in “Packet-Data Mode” with an assigned IP address, it can
be configured locally or remote over the Tetra Network.
For example, if the TMO-100 has the IP address 10.0.66.17 on the TETRA network
side, a remote PC can access this TMO-100 via another TMO-100 (here “the another”
TMO-100 is just used to link the PC to the Tetra network). In that case on the browser
input line of the PC http://10.0.66.17 followed by [RETURN] would access the Web
server of the remote TMO-100 that has to be configured.
Note that a registered port forwarding linkage has higher priority than the internal
functions of the TMO-100. Therefore, if Port 80 is assigned in the Port Forwarding
Table to an IP address of the local Ethernet, then the Web server of the TMO-100 is no
longer accessible remotely over the TETRA network.
V2.62B - Page 69 of 94
Funk-Electronic Piciorgros GmbH
5.2
TMO-100
Configuring the TMO-100 using MODBUS Protocol
The internal registers of the TMO-100 can be accessed using the MODBUS-RTU
protocol. Service information can read from the TMO-100, or its configuration settings
can be changed, using this access method. MODBUS-RTU access can be achieved
locally via the serial or Ethernet interface of the TMO-100, or remotely over the
TETRA network (only in packet data communication mode).
For this, the TMO-100 must be configure with a device address in the range 1 - 239
(factory setting = 1). This device address is the same as the MODBUS logical address
that is used for accessing the modem.
For access over MODBUS/IP, the modem responds to Port 4502. The standard Port 502
is not used because it has been assigned as a factory setting for communication with
external MODBUS devices thorough IP address 192.168.0.100.
The configuration registers of the TMO-100 are detailed in a separate document
(available on request).
5.2.1
Access through the Serial Interface
If it is requested to access the TMO-100 registers directly using the serial port(s), the
previously defined Modbus address has to be used.
This address can be configured using the “Device / Access” configuration menu.
Additional the COM or AUX port has to be set to “Modbus local”
Interface settings for Modbus access
5.2.2
Access through the Ethernet Interface
To access the TMO-100 through its Ethernet interface using MODBUS/IP, the Ethernet
IP address of the modem must be used (factory setting 192.168.0.99), and Port 4502
designated. The optional logical MODBUS address is ignored here.

Funk-Electronic Piciorgros GmbH
5.2.3
TMO-100
Access over the TETRA Network
The IP address of the TMO-100, statically or dynamically assigned by the TETRA
network, must be used when accessing the modem over the TETRA network. Port 4502
must be addressed. The optional logical MODBUS address will be ignored.

Auxiliary Functions
6.1
Sending Restart (Reset) and Ok-Messages
Optional the TMO can transmit OK-Messages to indicate its presents and proper
operation within the Tetra network. This message is sent as an SDS and contains the
Device-Name and the Receive Field strength, displayed in -dBm.
This option can be enabled in “TETRA Æ SDS/Status/MMI” by entering the time
interval (in minutes) between two OK-Messages.
Configuration of the OK- and Restart Message
As soon as an ISSI as programmed into the ISSI-Field of the OK/Restart box, a message
will be sent to an individual or to a group, if the device restarts. That can be used to
monitor the device-, the network- and the power supply behaviour of the remote TMO.
V2.62B - Page 72 of 94
Funk-Electronic Piciorgros GmbH
6.2
TMO-100
Monitoring the Receive Field Strength using a Status Message
In the menu "TETRA Æ SDS/Status/MMI" a status number can be predefined that is
used to monitor the receive field strength of the TMO. If the TMO receives this status
information, it immediately responds with an SDS that contains its Device Name and
the Field Strength value in –dBm. Using that feature, the device and also the Tetra
network can be monitored.
The ability to get the RSSI level from the device by this method can be limited to a
range of authorized SSI's. In that case only the SSI's in the defined range are able to
trigger that function.

TMO-100
Remote device restart using a Status Message
The TMO-100 can be restarted remotely by an incoming status message. The restart
will cause a complete reregistration at the TETRA network which may be useful under
some circumstances.
In the menu "TETRA Æ SDS/Status/MMI" a status number can be predefined that is
used for this. The feature is initially turned off for security reasons.
To enable this feature, it must first be set to "On", followed by a click on the "Apply"
button (or just pressing the "Enter" key). After this, the status number for this action can
be configured.
In this example, an incoming status message 50505 from an authorized calling ID (SSI)
can trigger the restart procedure on the TMO-100. Any triggered restart will cause an
entry in the eventlogger, including the SSI which has triggered this action.
The ability to get the RSSI level from the device by this method can be limited to a
range of authorized SSI's. In that case only the SSI's in the defined range are able to
trigger that function.

6.4
TMO-100
Speech Communication (Voice Function)
The optional voice function allows speech communication of the TETRA network,
between the TMO-100 and another station (e.g. a control room). A service technician
(for example) can call the control room to give a field report or notify an emergency.
For this, a voice transceiver (headset or handset) is connected to the TMO-100 (RJ-45
"Audio" socket).
The PTT (push to talk) pushbutton switch is pressed when speech communication is
required. When this happens, data communication is interrupted because simultaneous
data and speech communication is not possible. After the PTT button is pressed an
audio signal through the earphone indicates that voice connection has been established
and the user can now talk.
Data communication remains suspended while speech communication is in progress, or
until a silent period of 10 seconds is detected. Then the data link is re-established by the
TMO-100, and data communication is resumed.

Configuration of the voice feature
The configuration of the voice feature will be done on "TETRA Æ Voice". This menu
is available only if the voice feature is activated.
On the top of the page, up to 8 voice targets can be configured, each can be an
individual SSI or a group SSI.
The active voice target for outgoing calls can be selected below. The selection is limited
to voice targets where a SSI is configured, empty places (SSI=0) can't be chosen.
The selection of the voice target is avialable from firmware version 2.62, the previous
version do only offer a single number as voice target.
V2.62B - Page 76 of 94
Funk-Electronic Piciorgros GmbH
TMO-100
The voice call priority can be also configured, this will affect all outgoing calls from the
TMO-100.
It may be important that data communications by SDS has a high priority in the
application. As outgoing SDS can't be transmitted during an active transmitting voice
call, the "SDS priority in case of voice PTT" can be set. If activated, a transmitting
voice call will be disrupted for a short time if the TMO-100 needs to send out an alarm
or data SDS. The disrupton will be signalized by tones in the speaker handset.
Finally, the loudness of the speaker and the microphone can be adjusted on this page.
It's set to medium level by default.
V2.62B - Page 77 of 94
Funk-Electronic Piciorgros GmbH
6.4.2
TMO-100
Voice target selection with the speaker handset
Starting from February 2013 the TMO-100 will allow a selection of the active voice
target for outgoing calls by the speaker handset. This requires a hardware modification
and can't be upgraded just by software on older devices.
To switch the voice call destination, the small red button on the left side of the speaker
handset can be used.
With the first press of this button the active call destination (Voice-SSI 0 to Voice-SSI
7) will be displayed by a flashing LED on the RSSI LED bar. A flashing RF LED 5
means that the voice SSI "5" is selected for the next outgoing call. The initial press on
the button does not change the destination. The LED will display the destination for 3
seconds, then the display will revert to normal operation (showing the RSSI field
strength).
By pressing one or more times within the 3 seconds after the initial key press, the
destination can be changed. Each key press will increase the destination which is still
displayed on the RF LED bar. Unconfigured Voice-SSI will not be chosen, they'll be
left out by the selection process. If only the voice-SSI 1-4 are configured in the TMO100, only these destinations can be selected by this way.
The selection is made right when the flashing LED displays this, the call can be made
immediately after the successful selection of the voice target.
During the voice call, the active destination will be shown by an inverted flashing LED
on the LED bar. This will be the case on any call, not only after a reselection of the
voice destination SSI.

TMO-100
Control and Measurement I/O (RTU Functionality)
(Note: in the following paragraph Ports A, B, C, & D are not to be confused with IP
ports mentioned elsewhere in this document).
A version of the TMO-100 is optionally available with control and measurement inputs
and outputs integrated with the modem. The basic version has 16 on-off inputs (Ports A
and B) and 8 on-off outputs (Port C). A further optional version has Port D, which can
be ordered as 8 additional on-off outputs, or as 4 analog inputs.
Each of the 16 on-off inputs of Port A have independent event counting functions that
can be enabled by the user. Port A inputs counters operate as event counters, while Port
B counters operate as time-totalizing counters. The maximum counting rate [input pulse
rate] is 10 Hz.
The control and measurement I/O can be accessed using any of the following protocols:
•
•
•
•
MODBUS RTU through the serial interface or Ethernet interface, or over the
TETRA network.
IEC-60870-5-101 through the serial interface or over the TETRA network.
IEC-60870-5-104 (future: not presently supported)
DNP3 (future: not presently supported)
The RTU function of the TMO-100 can be configured so that a status change of an onoff input can cause an appropriate message to be sent (for example) to a TMO-100
Master Modem that has MODBUS access enabled, and stored there in a MODBUS
Alarm List. Alarms can then be sent to a control system for appropriate action.
6.5.1
Accessing I/Os using the MODBUS Protocol
The TMO-100 can be accessed remotely over the TETRA network or locally through its
serial or Ethernet interface. That access is made through Port 4502 (not Port 502
because that has been assigned as a factory setting for another communication
function). If the Port number is to be changed from the standard Port 502, the previous
entry (factory setting) relating to this Port is removed from the Forwarding Table, as
otherwise the TMO-100 will function as a router for MODBUS message frames and
pass these through to the local Ethernet, instead of reading and acting on them.
The I/Os are accessible as 16 bit values from the following register addresses:
Register
0 - 299
150-153

can be a failed or removed expansion module or a nonmatching I/O monitoring value.
The bit can be cleared if the status register is written with a
value where bit 6 is set. If the error still exists, the bit will
not reset to 0

I/O Presence Supervision
As up to 16 different I/O modules can be connected to the TMO-100, a various number
of digital and/or analog I/O can be available on the device.
Using the “RTU Features / Setup” for each type of I/O an individual monitoring can be
enabled. With that feature it can be avoided that when replacing an I/O module a
different one can be replaced (16 DI instead of 16 DO).
The same would occur if one expansion module would be taken out of the chain and not
be replaced.
Configuration of the I/O supervision
If the monitoring is enabled, the value entered in the RTU-Setup Menu has to match
exactly the number of physically connected I/O’s.
If it does not match, the device sets the I/O error flag in the status byte, the OK-LED
flashes on the front panel and all outputs will be disabled (set to off or zero).

T-Timeout
The T-Timeout refers to an internal TMO timer that monitors all access to the device.
Each time the TMO is accessed (e.g. by Modbus RTU protocol) this timer is reloaded
with the T-Timeout value.
If this timer has timed out (that means that there was no access over a period of time
due to network mal function or other reasons), all outputs of the device will be reset (set
to save state).
The T-Timeout can be enabled and disabled

Input Delay of the embedded Digital Inputs
If the TMO is equipped with embedded digital inputs (this feature is not available on
the extension modules) an On- and Off-Delay can be programmed for each of the 16
inputs individually. That protects the device from setting (or resetting) the input data on
each short signal change, caused for example when switching on or off huge loads on
the power line.
The delays can be disabled (factory default) or set in 100mS steps. It is also possible to
activate only the ON-Delay or both, the On- and OFF-Delay. In that case the delay in
ms will be the same for on and off.

Setting the TMO’s embedded Timer and Counter
Each of the 16 embedded digital inputs (this feature is not available on the extension

Counter or Timer.
A Counter can count events with a speed up to ten counts a second (10 Hz) and the
Timer is able to count the length of a signal (active low) in seconds.
Using the “RTU-Features / Counters”, each of the 16 digital inputs can be defined if it
will be used additionally as a Counter or a Timer. As a factory default, the input port A
(A0 – A7) is set to Counter and the input port B (B8 – B15) is set to Timer.

TMO-100
Master Modem for MODBUS Protocol
A TMO-100 configured as a master modem for MODBUS protocol can process status
messages transmitted by TMO-100 slave stations that have integrated inputs and
outputs.
As described earlier in this chapter, a TMO-100 slave station that has RTU functionality
(integrated I/O) can send predetermined status messages upon status change of specific
inputs. However, it should be noted that it can report such changes not more frequently
than 1 change per second.
If a TMO-100 is configured as master modem and local Modbus protocol is enabled, it
can be accessed using the Modbus RTU protocol. In such a case, it will reply to
MODBUS message frames that are sent to its MODBUS address, over the TETRA
network, from its local Ethernet, or through its serial interface.
Message frames from local terminal equipment that carries any other MODBUS address
will be forwarded over the TETRA network to the appropriate remote station.
6.6.1
Modbus Protocol with unsolicited Messaging
Additional to the answering of the normal Modbus polling algorithm from a SCADA or
PLC where the TMO-100 outstation acts as a Modbus slave device, it can send instant
status messages.
These messages can be enabled and are sent, whenever one of the 16 inputs of the
TMO-100 outstations changes their logic state.
The master modem stores these changes in a 16-bit register that is assigned to that slave
station. Such registers are available for each of up to 240 slave outstations. Each of
these registers, which are also writable, represents the current status of the 16 on-off
inputs of the corresponding slave TMO-100 RTU device.
Example: Monitoring an Alarm Message
If several slave TMO-100-RTU stations on a network are cyclically polled using the
MODBUS protocol then there could be a considerable delay for an emergency alarm
notification to reach the central control system by normal polling of the RTU stations.
In this example, when on-off input A0 of a slave RTU station is switched on (activated),
it means, that an alarm condition has occurred.
The central control system interrogates all existing slave stations by MODBUS RTU
polling. However, it also polls the mirror registers of the master TMO-100 that reflect
the inputs of the slave RTU stations. Because this interrogation does not go over the
TETRA network, but to the registers of the master modem, response to this polling is
very fast. In addition, the registers corresponding to several slave stations can be read
simultaneously.
As soon as in one of these registers Bit 0 is set (this corresponds to change in status
from "0" to "1" of the on-off input A0 of the corresponding slave station), the central
control system is immediately notified of an emergency condition and can take direct
action (for example, it can poll the alarm reporting slave RTU station immediately). In
V2.62B - Page 85 of 94
Funk-Electronic Piciorgros GmbH
TMO-100
addition, the central control system can reset the registers that mirror the slave stations'
inputs, so that the next change in status from "0" to "1" of the input of the slave station
results in a new alarm notification.

Start-Up / Troubleshooting
8.1
Brief Instructions
The following brief instructions provide a brief overview of the start-up steps for
putting the TMO-100 into operation:
8.1.1
Configuring the TETRA Network Parameters
The network parameters must be set into the TMO-100 (if this was not done at the
factory before delivery, for project specific orders): MNC, MCC, ISSI, frequency.
These settings are done directly in the TMO-100.
8.1.2
Antenna
Ensure that an antenna appropriate for the frequency band used by the TETRA network
is connected to the modem. An outdoor antenna will generally result in better
performance than a plug-in (modem mounted) corkscrew antenna. If the modem is
installed inside a metal cabinet, the antenna should be completely outside the cabinet. If
the modem is installed inside a steel-reinforced concrete or steel structured building, the
antenna should be installed outside the building.
8.1.3
Power Supply and Power-Up Sequence
When a voltage of 12-24 VDC +/-20% is applied to the power supply input terminalblock of the TMO-100, it starts up immediately. The "Pwr" LED lights up first, and a
short time later the "OK" LED lights up and stays continuously lit. If "OK" LED blinks,
this indicates as error condition corresponding to the blink pattern (see Section 2.3.1 OK LED: Blink Pattern Error Indication)
While the TETRA engine of the TMO-100 is being initialized, the LED lamps of the RF
signal strength indicator array flash in sequence, from right to left. When the
initialization is complete, the modem attempts to tie into the TETRA network. If this is
successful, then several consecutive LEDs of the RF signal strength indicator array light
up (the number of LEDs lighting up is proportional the RF received signal strength). A
minimum of 3 LEDs (from left to right) should be lit for reliable communication.
V2.62B - Page 88 of 94
Funk-Electronic Piciorgros GmbH
TMO-100
During the setup of the embedded Tetra engine, the LED display RF indicates the
LED’s stepping from right to left as a single dot.
Once the configuration is terminated and the device has successfully logged into the
Tetra network, a bar of LED’s (from left to right) indicates the RF field strength of the
received Tetra signal. For a proper communication, at least 3 LED should be indicated.
It should be considered, that the displayed RF field strength is the received field
strength from the base station and maybe the base station can still be received, while the
base station does not receive the TMO any more.

Power up Indication using a PPP Link (Packet Data Connection)
Once the TMO is configured for “Packet Data”, after logging to the Tetra network it
immediately tries to set up the PPP-Link indicated by the flashing blue PPP_L (link)
LED.
Once the link is established, the PPP_L LED will be continuously turned on, while the
PPP_D (data) LED only indicates transmitting and receiving data.
8.1.5
Failure to Register on the TETRA Network
If the TMO-100 does not succeed in registering on the TETRA network and all LEDs of
the RF Signal Strength Indicator are unlit, the antenna system modem settings of the
TETRA network parameters should carefully checked and corrected as necessary.
A TETRA terminal can be used to quickly determine whether TETRA network
coverage is available at a site. Take the TETRA terminal near the installed equipment
antenna. If the terminal (when it is switched on) indicates that it has tied into the
TETRA network, then the TETRA network coverage is available at the antenna
location.
If the TETRA network settings have been correctly done on the TMO-100, then the
antenna system should be examined to see whether it is correctly installed, and the
antenna has been correctly selected for operating frequency range. In addition, the
length and type of antenna cable are important considerations. If the antenna cable is
longer than 5m, low-loss cable should be used (e.g., RG-213 or Aircell). As a general
practice, it is recommended that the antenna cable is kept as short as possible (20m RG213 reduces the transmit and receive signal strength by half). Antenna cable loss should
be compensated by using an antenna of appropriate gain.

TMO-100 Firmware update procedure
The update mechanism of the TMO-100 was introduced with firmware version 1.16.
Previous versions can not be updated by this method, for such devices please contact
your Piciorgros partner who will be able to upgrade the devices to at least this version.
To perform the update, just a TFTP client is needed. A simple command-line client is
built directly into Windows operating system.
8.2.1
Preparation and setup
For updating the TMO-100 you will need the following equipment:
•
•
•
8.2.2
PC with Ethernet connection
TFTP client software (Windows command line or i.e. "PumpKIN" software)
Firmware files for the TMO-100
Update procedure
For the update, two firmware files are needed. The file with the extension ".pfw" is the
firmware file, the one with the extension ".pch" is the keyfile to activate the loaded
firmware.
To perform the update, the ".pfw" file must be sent first to the TMO-100. Unless the
".pch" file is sent to the TMO-100, the device will just store the new firmware file.
As soon as the matching ".pch" file is also transferred to the TMO-100, the device will
restart and reprogram itself to the new firmware.
Important!
This reprogramming after sending the ".pch"-file to the device will
take about 15-20 seconds. During this action, DO NOT INTERRUPT
THE POWER TO THE TMO-100. Otherwise the update fails and the
device must be restored by a Piciorgros partner.
After the update process has ended, the device will start immediately with the new
firmware.

TMO-100
Connecting the TMO-100
Connect the Ethernet port of the TMO-100 to the PC. The IP-settings of the PC must
allow it to access the TMO-100 (default IP: 192.168.0.199).
8.2.4
Update using the Windows command line client
Start the Windows command line by using "Start" / "Execute" and then type "cmd"
Change to the directory where you've put the firmware files
Transfer the .pfw file to the device, using the command
tftp –i 192.168.0.199 PUT filename.pfw
The IP here is the default IP of the TMO-100, if this IP is changed you have to give the
correct IP address instead. Also "filename.pfw" must be replaced by the real firmware
file name.
The transfer will take some seconds, unfortunately the software won't give you any
feedback of the progress. After some seconds you should see the success output like
this:

TMO-100
Now you'll perform the same action again, but now for the ".pch" file.
The device should restart now, doing the internal update process.
Important!
Do not disconnect the TMO-100 from its power until the update process
has finished (the TMO will not show any action on it's LED for about 1520 seconds, then it will restart). After the TMO has restarted and is alive,
the power can be disconnected.
The .pch file must always match to the corresponding firmware. Otherwise an error
message will be displayed and the update operation will not be started:
