3. Data transfer
3.1 Protocol 3964 R
The protocol for the serial interface corresponds to the procedure 3964 (R).
The data transfer is initiated by sending an STX character. The receiver must answer with
a DLE character within the stipulated acknowledgement delay of 500 ms.
The transmitter then switches to send mode.
If the receiver answers with NAK, a character <> DLE, with an incomplete character, or the
acknowledgement delay elapses, then the attempt to establish the connection has failed.
After three unsuccessful attempts, the transmitter interrupts the procedure and outputs an
error message to the higher level program.
If the connection is successfully established (receiver answers with DLE within the
acknowledgment delay), then the characters in the send buffer are sent to the receiver. The
receiver expects the data within a character delay of 128 ms. If this delay is not met, the
receiver sends an NAK character.
The transmitter then tries again to send the message.
After three unsuccessful attempts, the transmitter interrupts the procedure and outputs an
error message to the higher level program.
After the content of the buffer has been sent, the transmitter adds DLE and ETX as an end
marker. Then the BCC (Block Check Character) is sent. The receiver must confirm correct
reception with DLE within the acknowledgement delay, or indicate erroneous transfer
with NAK.

3.3 BCC Block Check Character
The BCC (Block Check Character) is defined by calculation.
During this process an EXCLUSIVE-OR operator is applied to all characters after STX.
The result is added at the end as the BCC character.
XOR operator
STX Data block DLE ETX BCC
Calculation:
1st character in the data block
XOR 2nd character in the data block
XOR last character in the data block
XOR DLE
XOR ETX
Simplification:
As the 2 special characters ETX and DLE are always present, these can be combined and
calculated separately to the actual data block.
The result for the data block is the subjected to an
EXCLUSIVE-OR operation with the constant 13H.
XOR nth character in the data block
= BCC
03H XOR 10H = 13H
BCC = (XOR data block) XOR 13H.
3.4 Examples for the determination of the BCC
Example 1:
Byte 1 STX
Byte 2 37H (37H)
Byte 3 DLE (10H)
Byte 4 ETX (03H) XOR operator
Byte 5 BCC
092491-07-01/09 Subject to technical modifications Page 7 / 34
The HBAS sends the key 7 (37H):
37H XOR 10H = 27H
27H XOR 03H = 24H
Simplification by combining DLE and ETX :
37H XOR 13H = 24H

4. Priorities on a data collision
The term data collision is used when a user receives an STX character while the
user itself is trying to send an STX character. I.e. both users are sending the STX
character at the same time.
To negotiate this data collision, the behavior of the HBAS on the occurrence of a collision
can be set.
Either the hand-held pendant station has priority, that is the HBAS sends its data first and
then receives the data from the control system, or the control system has priority and the
data from the control system are received first and then the data sent to the control system.
This setting is set either in the Configuration (Konfiguration) menu (see section 5) or
as a parameter using parameter transfer (section 9).
Priority:
The transmitter in the control system has high priority.
The transmitter in the HBAS has lower priority.
In the case of a data collision, this means that the HBAS detects an STX character when it
is also sending an STX to the control system, it interrupts its transfer and first receives the
data from the control system.
The data transfer to the control system is then repeated.
Example of a possible collision:
HBAS sends a key change
The control system sends "LCD text"
Solution:
First the control system sends and then the HBAS sends
HBAS
Control
system
Priority:
The transmitter in the HBAS has high priority.
The transmitter in the control system has lower priority.
In the case of a data collision when the HBAS detects an STX character while it is
also sending an STX character, the control system must also detect the collision and
acknowledge the data transfer initiated by the HBAS with a DLE character. Only after
the successful completion of the data transfer, the control system can start its data transfer.

5. Behavior on switch on / initialization
Immediately after the power supply is switched on, the HBAS is in an initial passive state.
The hand-held pendant station performs a self-test; this takes approx. 7 seconds.
After the self-test, a short sound is emitted and for 5 seconds it is possible to open the
Configuration (Konfiguration) menu using the <ENTER> key. The serial communication
interface is activated when this period has elapsed.
The EUCHNER LOGO is shown on the display and initialization by the control system
is awaited.
Until the initialization (see section 9) has been performed, all key operations are ignored.
5.1 Configuration (Konfiguration) menu
On the Configuration (Konfiguration) menu all parameters, that enable the hand-held
pendant station to be configured to meet specific requirements, can be changed manually.
It takes approx. 5 seconds to save a parameter change. The successful application of the
new parameters is confirmed by a short sound.
The Configuration (Konfiguration) menu is protected with a PIN. (Default setting on delivery
"1234").
The serial communication interface is shut down.
After the power supply is switched on, the text "Configure hand-held pendant station,
<ENTER>“ (Handbediengerät konfigurieren, <ENTER>) appears after the self-test.
The user now has 5 seconds to open the menu using the <ENTER> key.
After <ENTER> is pressed, a prompt for the PIN is displayed. A PIN with a maximum of
4 digits is to be entered. The exception here is the SuperPIN (151050) with 6 digits; this
PIN cannot be changed. It is possible to delete a character using the key.
The following settings are now possible:
Change PIN (PIN ändern) (section 5.1.1)
Priority (Priorität) (section 5.1.2)
Version information (Versionsabfrage) (section 5.1.3)
Pulse generator (Impulsgeber) (section 5.1.4)
Key click (Tasten-Klick) (section 5.1.5)
Firmware Update (section 5.1.6)
A selection is made using the keys, the selection is confirmed using <ENTER>.
The Configuration (Konfiguration) menu is left using the <ESC> key.
