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

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.

5.2 Setting the baud rate
The hand-held pendant station automatically detects the baud rate of the control system
and sets itself accordingly. Possible values are 9600 and 19200 baud.
This automatic setting is made on the initialization of the hand-held pendant station
(see section 9). A change to the baud rate can only be made when the hand-held pendant
station is briefly isolated from the power supply. On the subsequent re-initialization the
HBAS is set to the new baud rate.

6. Signaling
6.1 Acoustic signaling (command byte 52H)
An acoustic transducer is integrated into the hand-held pendant station. This can be
operated from the control system. For this purpose the command byte 52H must be sent
with the related parameters.

If an incorrect parameter is entered, the error byte is set to 34H.
The error byte can be polled using the status polling (section 9.1).
6.2 Optical signaling: Status LED
The Status LED signals internal program information. The user cannot access the way
the LED is operated.
The following information is signaled:

If the attempt to establish the connection from the HBAS to the control system is
unsuccessful, or if an existing connection is broken off (see section 3), then
the hand-held pendant station enters the error state and the Status LED flashes at
a frequency of 4 Hz.

7. Signaling a key change
Once the hand-held pendant station has been initialized and the communication with the
control system established, the corresponding key byte is sent to the control system on the
operation of a key.
Key byte transfer with simultaneous operation of several keys:
In principle the first key operated is always transferred.
If another key is already pressed when a key is operated, the second key is ignored,
a state change only takes place when the first key operated is released.
If a third key is also pressed, and then the first key released, the key information for the first
key is retained.

8. Pulse generator function
A pulse generator is integrated into the hand-held pendant station. This function is operated
using two keys that can be chosen as required. The keys are defined on the Configuration
menu (Konfiguration) (section 5.1.4). The default setting is the keys. The pulse
generator is also enabled on the Configuration (Konfiguration) menu.
The default setting is: "Activated" ("Aktiviert").
The operator can send counter pulses to the control system by actuating one of the
two keys. An RS422 driver module is used as the output stage; this contains the output
signals A, /A, and B, /B (see technical data).
If the key is pressed (or the key as defined by
customer) briefly, then 1 clockwise (CW) counter
pulse is sent.
If the key is operated (or the key defined by the
customer) 1 counter clockwise (CCW) counter
pulse is sent.
If one of the two keys is pressed for longer than the delay set (switch over from single pulse
to continuous sequence of pulses), then when this period has elapsed a counter frequency
in the corresponding direction is output. The value for this period and
the frequency are set on the Configuration (Konfiguration) menu (section 5.1.4).
Example:
Key for CW is operated for approx.2 seconds.
Delay set = 500ms, counter frequency set = 80 Hz.

9. Initialization
To enable the communication interface, the hand-held pendant station must be initialized.
The initialization is performed either by polling the current states of the keys with the
"Status polling" ("Statusabfrage") function (section 9.1) and the transfer of parameters
(section 9.2), or by sending another valid command byte (section 10.3 Overview of
commands).
The baud rate is also set on initialization (see section 5).
9.1 Status polling (command byte 23H)
The state of the keys and the error byte can be polled by the control system at any time
using the command byte 23H.
The error byte remains set until a status poll has been performed or a further error-free
transfer is made.
After the status polling the error byte is reset to 31H (no error).
It is recommended to perform a status poll for initialization after the reception of a NAK
character, as in this way the HBAS is reset.
The control system requests the current status from the HBAS

9.2 Configuration parameter transfer (command byte 53H)
All parameters that can be set on the Configuration (Konfiguration) menu can be
transferred from the control system at any time.
For this purpose the command byte 53H must be set before the parameter data.
After the data transfer has been started, the STATUS LED goes out.
The display is cleared and the text "Save param." ("Par. speichern") output.
A short sound is emitted by the HBAS as an acknowledgement of the correct storage
of the data in the flash and the text "Save param." ("Par. speichern") is cleared.
If a parameter is not given correctly, then the error byte "34H" is set. The error byte can
be polled by the control system by polling the status.

10. LC display
The display on the hand-held pendant station is operated in text mode. To display text,
the control system must send information on the type and the content of the display.
Text to be displayed frequently can be transferred to the HBAS at any time after
initialization and saved in the HBAS in a data memory (RAM). These items of text can
then be displayed using a short command (section 10.2.5).
It is also possible to define areas and to assign attributes to them. These areas can also
be displayed with a short command (section 10.2.6).
Controlling the LC display
Each LCD data block that contains a command for controlling the display must have the
LCD identifier byte as the first character.
This is defined as
An LCD data block can contain several LCD commands, however the block must not
exceed the length of 135 bytes.
Command to the LC display:
Control system HBAS/LCD
Byte 1 STX (02H)
Byte 2 LCD data block
Byte 3 DLE (10H)
Byte 4 ETX (03H)
Byte 5 BCC
6CH.
Byte 1 DLE (10H)
Byte 2 DLE (10H)
Important!
It is not allowed to interrupt a data block that has already been confirmed with DLE.
Prior to a new transfer, it is necessary to check the receive buffer for a STX from the
HBAS.

10.2.2 Character output
To output a character at the current position of the cursor, it is sufficient to write this
character to the data block. The cursor is then moved forward one position (except at the
end of the display). At the end of the line a LF is performed. On the last line at the last
position, the cursor remains stationary and writes the remaining text at this position.
Example:
The text "Euchner" is output at the current cursor position

Explanation on the font size:
The character set can be displayed in 2 different font sizes. Characters can be displayed
in both font sizes at the same time.
When the font size is changed, the cursor is automatically set to the start of the display.
Small font: The display is divided into 8 lines and 16 characters. The individual
characters comprise 8x8 pixels.
Large font: The display is divided into 4 lines and 8 characters. The individual
characters comprise 16x16 pixels and are thus twice the size of the
small font.

10.2.5 Text commands
The user can define up to 200 different items of text and their position on the screen
and display the items of text using a short command. An item of text is allowed to be
a maximum of 30 characters long.
The text definitions can be made at any time. If an item of text already defined is re-defined,
the old item of text is erased. Within a defined item of text, other LCD commands are also
allowed, thus longer command sequences can also be opened using the short command
(macro function).
If an item of text that has not yet been defined is to be output, the error byte is set to 34H.
The error byte can be polled using the status polling (section 9.1).
