1.1 Important comments for application!
Initiation
Remove devices from packaging. Keep packaging material for future shipment
purposes!
Accu blocks are not inserted in HW 90196 at time of delivery. After unpacking of
box accu blocks have to be inserted in HW 90196.
A final functional test of the HW 90196 and its peripheral devices should be
performed before delivery to customer.
Application
• Operate devic e on l y with cont ain ed equ ipment.
• Keep device from humidity and dust.
• Clean device only with damp cloth and mild detergent.
• Do not insert objects other than applicable into openings of device (risk of
destroying electronical system).
Safety
• Do not operate in close range of strong electromagnetic fields.
• Note temperatur ranges under sec. 3.1 (avoid over-heating: e.g. due to stor-
age in direct sun light impact area behind windows [like in a car]).
• Protect against theft and abuse (terminal HW 90196 may contain great financial values
• Pay attention to plug-ins (dealer card)
Storage
A terminal HW 90196 must only be stored without accu block!
(Accu block should always be stored seperately in charged condition.)
Shipment
Device must only be shipped in original or comparable robust packaging. Conventional paded bags do not protect the HW 90196 against shocks and pressure sufficiently. Non-applicable packaging means have to be assesed as negli-
gent.
Maintenance
The HW 90196 is – apart from charging of accu block and above mentioned
comments- lifetime maintenance-free.
Opening of
HW 90196
The HW 90196 does not contain any components which could be maintained,
replaced or repaired by the customer or personell other than the H&W service
personell. The casing screws of the HW 90196 are sealed to keep from nonauthorized opening. Opening of device provokes data loss.
IMPORTANT!
1. This device must not be changed or modified unless expressly approved by
Vectron Systems AG. Any unapproved modification could void the user´s
authority to operate the equipment.
2. Damages of device due to non-applicable packaging means during shipment or
due to non-authorized opening will cause invalidity of warranty!

3.4 Power consumption
Following table shows an approximate overview of power consumption of mobile terminal HW 90196 at
different operating states (BIOS terminal:‘09905, firmware radio module: #09907). The measured values
during operation depend on the current accumulator voltage. The measurement has been taken with an
accumulator voltage at 3,8 V while discharged accus provoke higher currents. The operating status of the
radio module has a significant influence of the overall power consumption of terminal HW 90196. In particular, if the terminal is switched off or outside radio frequency range (see No. 8, 12, 6, 4, 2), programming should meet these conditions, e.g. by switch off with bios_sleep() (see No. 13) after time out. Also, if
no optical warning can be indicated on switched off display of terminal (see No. 11 & 12) and radio connection is still running after a time out, the terminal should be completely switched off by bios_sleep()
(see No. 13).

4.4 Maintenance of accu block
If accu blocks are stored, they should be re-charged on a regular basis. After a period of 6-8 weeks, even
a new accu block is discharged to such an extent due to self-discharge that it is no longer possible to
operate a HW 90196 with it.
About how to store device and accu block see also 1.1 „Important comments for application“.
IMPORTANT!
A stored MDE which is not used, has to be recharged once per month.
The maintenance and service of such accus which have not been used for a longer period may
be executed by the Höft & Wessels service department. For further information, please contact
our service line : Tel. (0049) 01803/ 23 28 29
As for maintenance of the accu block, the following points should be taken into account:
Good:
• Daily use of the accu block
• Total use of capacity (discharge) until display shows "attention! - recharge batteries!!!"
• Re-charging with charging unit HW 16196 or communication station HW 50196
Bad:
• Occasional use of accu block
• Heat impact (increased self-discharging)
• Frost impact
Very bad:

4.5 Disposal of used accus
"NiCd-accu cells contain between 15 and 20 % highly toxic cadmium."
(Source: test 12/88 p. 1175)
Used accu cells must under no circumstances be disposed with common household waste, as the con-
tained cadmium will result in heavy pollution of environment.
All used accu cells have to be disposed of in an appropriate way. For this purpose, they have to be re-
turned to Höft & Wessels. As a part of its normal service, Höft & Wessels guarantees that all used accu
cells are fed to the recycling process.
The return of the accu cells ensures 100% reuse of the chemicals contained. This recycling process
avoids any impact to the environment.
See also extract from BattV - 01.10.1998:
"The manufacturers are obliged to take back and reuse toxic containing batteries according to the regulations and dispose of non-reusable batteries that have been handed in by distributors (§5) or public disposal departments (§9).“

5. Operating system
Preface
Those functions which are explained in this chapter are installed as standard features in the operating
system of the HW 90196 and are independent of the type of application program. The user will usually not
have to deal with the operating system, as during normal operation only the displays of the application
program are presented. These are explained in detail in the corresponding documentation of the application program.
For special purposes it may however be useful that the responsible support person of the HW 90196 uses
the functions of the operating system explained in the following. Note that by means of the functions given
below, individual data as well as complete programs may be deleted!

5.2 Warm start
A warm start is the complete initialization of hard- and software.
After a warm start (message: Ws!->C) an application program will be started automatically, if an
autostart file with any name and the extension „AST“ has been generated beforehand on the disk. This
automatic restart process can be supressed by not activating „C“ but the „F1“-key followed by keys
„2071828“. After this, the functions of the operating system-basic menu can be used.

5.3 Reset
A reset means the most profound level to process an initialization of hard- and software. The reset provokes an abandonment of the running application programm at any given position. To proceed, the reset-key in the accumulator compartment may be activated. Note that the accumulator block should only
be removed if the HW 90196 is switched off, as otherwise files could be damaged during running write
operations.
If an application program is stored on the Flash-Disk, it will be started automatically after a reset with the
stored file and extension „AST“ without needing further instructions of user. The automatic start of the
application program after reset can be suppressed by activating a combination of keys as followed: press
at same time: „F1+F4+0“. Only in this case the operating system will check the Flash-Disk.
The following message „Ws! -> C“ must not be confirmed with the ‚C‘-key as otherwise the application
program will be automatically started (see chap. above 5.2).
In order to initiate a reset, proceed as follows:
1. Take out the accu block (with switched off HW 90196).
2. Press the reset-key which is located under the accu block and above the sticker (see also
fig 17, p. 52).
Do press the reset-key carefully, with low expenditure of force. You may want to use a bend up
paper clip, e.g..
3. Insert the accu block. The HW 90196 is automatically switched on again.

5.4 Format FLASH-Disk
Note!
The procedures described in this chapter will delete all data and programs on the HW
90196 and should thus be executed only in emergency cases!
The FLASH-disk in the HW 90196 is administered as a virtual hard disk. In order to delete all files on a
disk, it has to be formated anew just as a floppy or a HD.
The process starts with the following display:

5.5.2 Functions
All avaible functions, their expressions, display indications and commands that will be transmitted to the
radio module within the configuration mode, will be explained in the following. These functions are also
selected by the enter- and arrow-keys. Due to the changed format of the commands all functions are
classified as new and old firmware. The radio module firmware version will be determinded before transmission of a command.
These functions prove to be advantageous as they enable a configuration of the radiio module without
having loaded an application program beforehand and thus an application program can later be duplicated onto the Flash-disk via radio connection. Even in the case of an unintentional delete of the application program at the customers place, the terminal does not need to be sent to the service department.

6.1.4 Power consumption
Following table shows an approximate overview of power consumption of mobile printer HW 90195 at
different operating states (BIOS printer #09906, firmware radio module: #09907). The power consumption
during printing depends much on the print image. The pulse motor will be supplied with power for 15 seconds after each printout (see 2), holding the printout tight for easy tear off. During this period of time the
mobile printer can turn to operating state 5 as a result of a canceled radio connection. If the mobile terminal is switched off or out of radio range, the power consumption will be significantly increased (see 6&4).

6.2 Functions
6.2.1 Operating modes
On
The green LED of the printer is switched on or flashing (depending on charging condition of accu). Printer can be switched off with on/off-key.
Off
All LEDs of the printer are switched off. Printer can be switched on with on/off-key.
Printer turns to sleep mode immediately after switch on.
Sleep mode
The printer turns immediately after switch on from off-mode, resp. after a period of 30
seconds with no radio connection, to sleep mode (green LED flashes every 2 seconds).
The printer can be activated with the on/off-key or via radio by the Base Station. Now
the printer is switched on. To activate the printer via radio a signal will be sent to the
printer to establish a connection. If the printer turns to the sleep mode because of the
30s-time-out function, the connection will still remain for further activation processing.
Note!
The printer should always be switched off after operation (do not let the printer remain at
sleep mode).
If the printer will not be used for a long period of time ( > 1 day) , take out accu block.

6.2.2 Function indication LEDs
A list of all LED-combinations will be shown in the following.
The green LED usually indicates the accu charging condition:
• on = „ok“,
• flashing = „low“ oder „discharged“.
The red LED indicates several error conditions:
• off = „ok“,
• on = „no paper“ resp. „open casing flap“,
• flashing = „no radio connection“.
Additionally, the green LED flashes every 2 seconds, if the printer is at sleep mode. Update processes
and the inital switch on from „off-mode“ are the exceptions.

6.5 Printer malfunction
Malfunction Elimination
Printout is not ejected poperly. Check, if paper reel has just been inserted. If so,
take reel out and insert again.
The HW 90195 stops during printing and shows no
more reaction.
The accu block is almost completely discharged
and HW 90196 stopped printing. Recharge accu
block or insert a recharged accu block.
Printing does not start. Read messages in display of terminal.
No message about end of paper reel, printing can
be continued.
Open flap of paper reel casing. Clean sensor for
„paper end“ by blowing out printing unit.
All recieved but not yet printed characters are de-
leted after interruption of connection, resp. connection establishing, by the radio terminal because of
impossible feedback to radio terminal without radio
connection.
After establishing a new connection the printout can
be repeated.

6.6 Special features of printer
Paper hold:
After printing the last line the printer holds on tight of the printout for 15 seconds by motor power to faciliate the tear off. After this period, resp. if the accu is low, discharged or taken out, the printout needs to be
torn off more carefully. It is also programmable that the radio connection is canceled after the printout.
The printer then turns to sleep mode.
Establish/Cancel the radio connection:
The printer is activated from sleep mode by a RING-signal of the integrated radio module. The printer
awaits the establishing of a connection to the Base Station for the following 30 seconds. If no connection
will be established, the printer turns back to sleep mode. After a succesfully established connection the
printer awaits either print data or the intentional cancellation of the connection by the Base Station. There
is no time-out after the printer has turned to sleep mode.
Infrared-command-mode
The printer turns from sleep mode to infrared-command-mode by pressing the on/off-key. Now the printer
can be configured by the terminal and the IR-interfaces of both devices. The IR-mode will be abandoned
after a time-out of 30 seconds. By pressing the switch on/off-key during IR-mode the printer is switched
off.

7. Base Station HW 8660
The HW 8660 is the base station for radio data transm ission. It is suitable for com munication with devices containing Radiomodules of Höft & Wessel.
Peripheral devices like modem, printer etc. can be connected via serial interfaces.
The radio base station is network-compatible, applied protocol is TCP/IP via ethernet.
It is the main task of the Base Station, to relieve the receiving PC from data transmission tasks with critical time conditions. The Base Station is capable to perform data telecommunication with MDEs via ISDN
terminal adapters, modem or interfaces automatically.
The Base Station HW 8660 is connected directly with a local network via ethernet allowing easy scaling of
the central system setup. Any number of MDEs can be applied for the network depending only on the
number of desired communication lines. One Base Station can serve up to four lines at the same time.
NOTE!
1. Use connections only as specified in operating manual (note on rear side).
2. Do not connect with any telecommunication means, like e.g. ISDN-components.

9. Connection of the HW 90196 and HW 90195 via radio transmission
9.1 General
The digital radio data transmission allows the application of mobile devices as online-terminals. The location independent online-access and/or –transmission of relevant data faciliates timing and coordination of
complex schemes in areas as mobile data registration or catering. The interaction of components in a
local radio communication network will be explained in the following.
The radio base station HW 8660 operates as a crossover for multiple serial interfaces and provides a
network gate for radio connections with TCP/IP. The principle works out as followed:
Program-in/output-data from the server is transmitted via the Base Station to the mobile terminals. The
Base Station serves hereby as a converter translating the relevant data reciprocally into a format that is
readable for serial resp. radio network accesses.
Another function is Roaming. Mobile terminals can be used location independently in a networked environment with several Base Stations. The radio connection to a mobile terminal is taken over by the Base
Station with the strongest radio signal. Every communication operation, independend of the range, is
transmitted to the virtual control panel.
This allows many different application possibilities:
The MDE can operate as a mobile terminal with the server running the program and the mobile terminal
presenting the program surface. This way the whole range of standard-TCP/IP-applications can be presented on a mobile terminal.
Also the mobile terminals can run their own applications. In this case the Base Station can be used to
read master data or sales data for analysis and transmit these to the server. This eliminates the need for
physical temporary storage devices or wired connection of the terminal with the network.

9.3.1 Initial logon of MDE
• The radio fixed part (in Base Station) sends program Switcher signal information about established
connection to Mobile Part (=radio module in MDE).
• Switcher determines serial number of MDE.
• By network broadcasting Switcher checks, if there already is a Base Station which has operated this
MDE. It will recieve no response as this is the initial logon.
• Switcher starts a local Gelnet.
• Gelnet starts a Telnet and logs on to host with user name and password.
• The application on host is started.
• Switcher transmits all data from/of the serial interface to local Gelnet and vice versa.
• The communication line between MDE and host can be described as followed:
MDE – Radio MP – Radio FP (Base Station 1) – Switcher (Base Station 1) – Gelnet (Base Station 1)
– Telnet (Base Station 1) - host
9.3.2 Repeated logon of MDE
• The Radio fixed part (in Base Station) sends program Switcher signal information about established
connection to Mobile Part (= Radio module in MDE).
• Switcher determines serial number of MDE.
• By network broadcasting Switcher checks, if there already is a Base Station which has operated this
MDE.
• As the MDE has alre ady communicated with a Base Station the Gelnet of this Base Station sends a
message. This can – but does not have to be – identical with the current Base Station; to explain this
more clearly, it is suggested that the MDE has now a connection with Base Station 2.
• Switcher transmitts all data from/of the serial interface to remote Gelnet and vice versa.
• The communication line between MDE and host can be described as followed:
MDE – Radio MP – Radio FP (Base Station 2) – Switcher (Base Station 2) – Gelnet (Base Station 1)
– Telnet (Base Station 1) – host

The frequency stability of the radio frequency carriers at the transceiver shall be better than +/- 50 kHz
under extreme temperature conditions.
10.4.2 Carrier modulation
For transmission of binary data on a frequency channel, GFSK modulation is used. The nominal modulation equals 400 kHz. The modulation is performed on binary symbols (1 symbol = 1 bit). The symbol clock
equals 1.152 Mbit/s.
10.5 Multiplexing
A transceiver may operate either as Basestation or as Endpoint of a radio network. A basic network comprises a single Basestation and multiple Endpoints. Communication happens always between an Endpoint and a Basestation, i.e. there is no direct Endpoint-to-Endpoint communication.
Communication is based on connections. Establishing a connection means in fact the allocation of radio
spectrum resources for a specific link between an Endpoint and a Basestation. Multiple connections may
be active at the same time.
Moreover there is the requirement of sharing the radio spectrum with other low power devices operating
in the same band.
The radio spectrum is shared through a combination of time and frequency multiplexing.
10.5.1 Mult iplexing in the Time Domain
The system used TDMA based on a 10ms time frame containing 11520 bit. The frame is divided into
K=24 time slots numbered k=0 to 23 in the order of transmission. Each time slot contains 480 bit. This
corresponds to a slot time of about 416,7 µs.
A connection is built by one or multiple bearers. A bearer is a sequence of transmissions occupying the
same time slot in a number of consecutive frames. Each transmission is a burst, starting with a preamble
followed by a synchronization word and payload data.
So a bearer is a sequence of burst transmissions. The duty cycle of a bearer is 1/24.
For the internal administration of the system a multiframe consisting of 16 frames and a superframe con-
sisting of 3 multiframes (i.e. N=48 frames) are defined. Each frame is numbered according to its position
in the superframe. Frame numbers range from n=0 to 47.
10.5.2 Mult iplexing in the Frequency Domain
The system uses fast frequency hopping for multiplexing in the Frequency Domain. The hopping time, i.e.
the period between two consecutive hops, equals 10ms and is synchronized to the TDMA frame clock.
This frequency hopping scheme implies that consecutive transmissions for the same bearer always use
different frequency channels. The actual sequence of frequencies is defined by a so-called hopping pattern.
A hopping pattern is a mapping of the frame number onto a corresponding frequency channel number.
Since the frame number is periodic with period N=48, also the hopping pattern is periodic with N=48.

10.5.3 Generic frequency hopping patterns
I=46 generic hopping patterns are defined. Each generic hopping pattern uses all 48 frequency channels.
Over a period of the hopping pattern, each frequency channel is used during a single frame. Therefore
the signal power is distributed uniformly over all frequency channels.
All 46 generic hopping patterns are listed in table 2. Each sequence f(i)[n] occupies two rows in the table,
the first row containing f(i)[0] to f(i)[23], and the second row f(i)[24] to f(i)[47].

Each basestation has assigned a fixed generic hopping pattern. Co-located basestations may use the
same generic hopping pattern or different generic hopping patterns without restriction.
Endpoints support the whole set of generic hopping patterns. When an endpoint establishes a connection
to a basestation it detects, during the synchronization procedure, the generic hopping pattern to be used.
10.5.4 Hopping channels
Hopping channels are derived by shifting a generic frequency hopping pattern along the time axis. For
each generic hopping pattern f(i)[n] a set of L=12 hopping channels h(i,l)[n] is generated through the following equation: h(i,l)[n] = f( i)[n- 8l ]
10.5.5 Bearer position
The position of a bearer in the combined time / frequency multiplex is marked as b(i,l,k), where
i denotes the generic frequency hopping pattern
l denotes the hopping channel
k denotes the time slot
10.6 Medium Access Procedures
10.6.1 Synchronization
Two transceivers are synchronized, if their bit clock, frame clock, multiframe and superframe clocks are in
phase alignment and they use the same generic hopping pattern.
In a basic network the basestation is the synchronization master and the endpoints are synchronization
slaves, i.e. the endpoints synchronize their clocks to the basestation.
Even when no connection is active, any basestation sends a dummy bearer. On that bearer all information is contained which is needed by an endpoint in order to establish synchronization to the basestation.
The dummy bearer is sent using the generic hopping pattern f(i)[n] on an arbitrary bearer b(i,l,k). Before
setting up the dummy bearer, the basestation performs RSSI (Received Signal Strength Indication) scan
on all available bearer positions and selects the quietest bearer position.
During dummy bearer operation the basestation observes adjacent timeslots in order to detect sliding
collisions. In this situation it will move the dummy bearer to another bearer position.
Information contained in the dummy bearer contains the identification of the generic hopping pattern used
by the base station.
An endpoint obtains synchronization by continuously scanning a single frequency channel. In the course
of its hopping pattern the dummy bearer of the basestation will hit this channel every 480ms. In this event,
the receiver obtains bit synchronization from the synchronization word and it retrieves the generic hopping pattern f(i)[n] from the information contained in the dummy bearer.
Although at this stage of synchronization the actual hopping channel and time slot are still unknown to the
endpoint, it is already able to set the correct frequency channel for the next transmission burst of the
dummy bearer. By monitoring the dummy bearer over a several frames, the endpoint retrieves all required information to establish and maintain synchronization of frame, multiframe and superframe clocks,
including the values of l and k for the dummy bearer.
An endpoint will not transmit any radio signal before it is synchronized to a base station.

10.6.2 Monit ori ng of the environment
Both sides, basestation and endpoint regularly and independently perform RSSI scans of all accessible
hopping channels and time slots. The basestation broadcasts on its dummy bearer a list of allowed hopping channels and time slots. Any endpoint maintain a list of quietest channels, i.e. preferred values (l,k)
for setting up a connection.
10.6.3 Sett ing up a connection
Connection setup is always initiated by the endpoint. It selects values (l,k) depending on its RSSI measurements and the information received through the dummy bearer from the basestation. It then starts
transmission on the selected traffic bearer b(i,l,k).
The basestation regularly scans through all accessible bearer positions. This is referred to the Primary
Scan function of the basestation. Information about the primary scan is broadcast on the dummy bearer,
so when the endpoint establishes a traffic bearer this is done exactly at the time when the basestation
scans the respective bearer position. This allows the basestation to answer the bearer establishment
procedure and set up a connection.
10.6.4 Connection maintenance
As long as the connection is required (by higher layer protocols) it remains on the selected traffic bearer
b(i,l,k) unless a bearer handover procedure is invoked.
During the connection both transceivers monitor the quality of service on the traffic bearer. This is done
through RSSI measurements in adjacent time slots and bit error measurements. In case the quality of
service falls below a certain threshold, a handover procedure is started. It is always initiated by the endpoint.
During handover a new bearer b(i,l_new,k_new) is established and the old bearer is closed down. Selection of the new bearer happens according to the same rules as for a new connection, i.e. involve RSSI
measurements.

10.7 Interference avoidance strategies
10.7.1 Interference within the system
The medium access procedures provide sufficient mechanisms so that there is no relevant interference
within a system.
Only endpoints send out a signal that are synchronized to the basestation.
In a synchronized system only signals interfere that use the same bearer b(i,l,k). Due to the fact that the
basestation broadcasts a list of free channels and each endpoint performs RSSI measurements, the only
potential interference situation is a collision of two endpoints during connection setup. Such a collision is
detected at both endpoints which then re-attempt to establish the connection after a variable timeout. So
the probability is very low that the two endpoints collide again .
10.7.2 Int erference between two systems of the same type
In case two systems of the described type are operated in the same location, they may interfere with each
other. There are two possible situations:
1. Both system use different generic hopping patterns. In this case connections belonging to different
systems may hit the same frequency at the same time. Due to the bursty transmission a collision occurs only, if the connections use the same time slot and the same frequency channel. So the total
collision probability is (1/24)(1/48) < 0,09%. The system is tolerant to a certain amount of interference. Packet loss is detected and corrected through re-transmission. Only if a significant amount of
packets is lost (say 10%) this will reduce performance.
2. Both system use the same generic hopping pattern. This case is further studied below
Each of two systems using the same generic hopping sequence recognizes (through RSSI measurement)
the bearer positions used by connections of the other system. So it avoids these bearer positions.
Since the two systems are mutually not synchronized, they drift against each other. The maximum relative drift is given by the oscillator accuracy of 10ppm. For drifting one slot position at least 2 seconds are
needed.
In this case slow sliding collisions occur. The system invokes bearer handover to solve sliding collisions.

Lin 02.02.2001 1.00 HW90195UserMan.doc Subject to amendment, errors excepted
10.7.3 Int erference from other sources
Other frequency hopping systems may cause occasional packet loss which is solved through packet retransmission.
The same applies to CW interferers.
In case the interference pattern of a specific interferer tends to disturb specific time slots or hopping
channels, the system will avoid these channels.
Since the hopping is fast and is spread over the whole band it may stand even interference from micro-
wave ovens.
The presence of direct sequence spread spectrum systems will cause an increased noise floor and re-
duce the coverage range. However, GFSK modulation has a strong noise immunity.
10.7.4 Int erference to other systems
In case the system detects other transmissions during a number of consecutive frames it will perform
bearer handover to a quieter channel.
The low duty cycle and the fast frequency hopping are helpful in reducing the amount of interference to
other systems.
