1 General
This document contains the description of the software CPT4SBS in combination with
the T/R-Twin hardware for a separationbox.
The Transmitter/Receiver Separation Box Standard is used for identifying, separating
or separating/weighing of cows. The separation system uses one antenna.
CPT4SBS
Poiesz Twin VC4 Separation Box Standard.
Description of the code : Cattlecode
2 Operation
• Every cow is stopped at the hold-gate
• After identification of the responder the T/R sends a request for separation-data
• If weigh computer is connected, wait for weigh data
• When weigh data is received and separation data is received the separation gates
are set, the hold gate will open
• After hold gate is open the twin is waiting for IR2 (only if responder is out of the
antenna)
• As long as IR2 is activated the hold gate will not close
• When IR2 is free the hold gate will close
• When IR2 is free, IR3 is already activated
• Station is ready for the next cow as soon as IR3 is free
• Cow is stopped at the hold-gate
• IR1 is activated, twin remains waiting for responder number
• After maximum ID time the cow will be sent to the default exit

The Nedap guarantee-regulations are only valid when the T/R is mounted and
installed as indicated in this chapter. The following is important :
The antenna must be installed around the station (see figure 5). When the HF-field is
To install the T/R Twin correct, some jumper settings must be checked or changed.

4 Set Address
The address setting concerns the following menus and procedures (see figure 3):
For communication the Transmitter / Receiver needs an address. Then the computer
knows where to send the information to. At the transmitter / receiver with help of the
display and the push button the stations address is configured.
The two segment display and the yellow push-button must also be used for several
adjustments of the Transmitter / receiver. A number of different codes will appear on
the display when the push-button is pushed, these codes represent the so-called
menus. Each menu on its turn is divided into a number of functions. By varying the
pushing time of the push-button, you will get access to the different menus and/or
functions.
The first time you switch on the power of the T/R, the display will show "0-". The
Transmitter / Receiver asks now for the first address. When an address is entered the
display will blank out and the transmitter / receiver returns to the normal status.
Address menu
- Set Address
- display Address
The address-range of all connected peripherals on the same controller channel
is from 1-50.
Remember that the used peripheral-address has to be unique on this controller
channel.
When the display shows SA, the "Set Address procedure" is entered by pressing the
button until the display blinks. The procedure is as follows :
display scrolls from
display scrolls from x0 through x9
to indicate that the "Set Address procedure" has been entered, the display will
show "0-"
• by pressing the button short, the next decimal will be displayed ("1-","2-"...."5-")
• the displayed decimal is entered by pressing the button until the display blinks
• when the decimal has been entered, the display will show "x0" (where x = entered
decimal), the unit-digit now can be entered
• by pressing the button short, the next unit will be displayed ("x1", "x2", .. , "x9")
• the displayed unit is entered by pressing the button until the display blinks
the "Set Address procedure" can be quit by pressing the button until the
display blanks. The entered digits then are not stored
• the T/R will restart when the address is changed
When the display shows dA, the "display Address procedure" is entered by pressing
the button until the display blinks. The display then shows the T/R address.

Identification
The antenna adjustment-procedure consists of several steps. It is essential that
these steps are executed in the sequence as in the manual described.
During T/R start up there is auto detect of T/R type, 120kHz (for rA and rP) or 134.2
kHz (for ri and r2)
rA = AM labels, X-ponder and Respactor (default)
rP = PM labels, ear button and Phase code responders
ri = ISO responder types (default)
r2 = Nedap 2 hour activity meter (Lactivator)
Select rS on the display and select the required type, press until display blinks to
store the setting.
HF menu, select H1 for antenna 1 or H2 for antenna 2
The antenna adjustment-procedure consists of several steps. It is essential that these
steps are executed in the sequence as described. First "AA", then "AP" and last "AS",
described in step 1, 2, 3 and 4.
While tuning Lt the following must be noted
• The tuning of Lt must be done with a non-metal screw-driver (e.g. plastic)
• This tuning of Lt requires a short circuit of the "Antenna adjust input" on the T/R,
see jumper settings.
• It is possible that the trimmer-coil must be turned so far out of the coil housing that
the transformer box does not close anymore. In that case, turn the trimmer-coil
completely in the coil housing. In this way the same adjustment can be achieved.

The transformer-ratio determines the HF-current through the loop-antenna, which
determines the power of the HF-field. In principle the highest transformation-ratio
should be selected. This however can be limited by the fact that the antenna-circuit
then can not be brought in resonance anymore (= highest value on the display).

The following has to be done
turn the trimmer coil (Lt) completely in the coil housing.
• connect HF-output of T/R (HF +/-) to input of ANT-T with the transformation-ratio

select AA (Adjust Antenna see figure 2) on the display, then push the button until
the display starts to blink.
• with P1 (figure 1) the displayed value must be set to 30
• after adjusting P1, the value must be adjusted with Lt (figure 1) on the EWA
transformer to a maximum value. Tune (with plastic screw driver) the trimmer Lt
on the antenna transformer until the highest point has been found (is highest
display value, this means when you are turning further in the same direction the
display value must go down after the highest level has been found, if not select a
different transformer ratio.)
• connect HF-output to the next transformer-ratio 9 : 1, or 11 : 1 (do not change HF+
and HF-), try if a higher value on the display can be found by tuning Lt.
connect HF-output to the highest transformation-ratio (with the highest value on
the display) where it is still possible to find the highest point, this is the right
adjustment.
• When the right transformation ratio has been found Lt must be tuned to the
maximum

Advised and Default Squelch settings CPT4SBS
After correct processing the antenna adjustment procedure, step 1 and 2 are done
and Lt is adjusted (highest value is on the display now ), P1 must be adjusted with
help of AP.
When the display shows AP, the "Adjust Power procedure" is entered by pressing the
button until the display blinks. The display now shows the percentage of the
maximum transmitting-power of the T/R. The T/R is equipped with a power-limitter.
When the transmitted HF-power exceeds a certain level, the HF-current will be limited
automatically. To indicate this, the display will blink, after this point power-increase
(P1) is not desirable.
The tuning-procedure is as follows :
You can continue by pressing the button short
The adjusted squelch determines the sensitivity of the receiver in the T/R. In case
Twin Feeder Model 1 Squelch = 0
Twin Feeder Model 2 AM CODE Squelch = -2
Twin Feeder Model 2 PM CODE Squelch = -1
Note : AS can be used to reduce the HF-field if animals are identified outside the
e.g. calves outside the station are identified, the transmitted power can be reduced
("Adjust Power procedure") or the receiver-sensitivity can be reduced by means of the
squelch-adjustment.
When the display shows AS, the "Adjust Squelch procedure" is entered by pressing
the button until the display blinks. The display now shows the actual sensitivity of the
receiver, a value from "-0" (most sensitive, i.e. default setting) until "-3" (least
sensitive).
By shortly pressing the button, the desired squelch can be adjusted. The setting can
be entered by pressing the button until the display blinks.

starts to blink
