    Serial Communication Protocol (V1.7 & 2.x)
General Description
The Abacus/Arcus software is able to make serial connection link to a receiver device (e.g.
computer) which is connected to the serial port. If the Baud Rate setting in the Service Menu
is set to a valid value (other than Not Connected), the instrument will try to initiate a
communication sequence.
The serial communication is always initiated by Abacus/Arcus, and the receiver must
respond to this.
The hardware protocol: 8 data bit, 1 stop bit, no parity. If the other side is not responding in
1 second, the instrument will repeat the transmission twice, but if still no response, the other
side will be supposed to be not ready to receive data, and thus Abacus/Arcus will not try to
communicate any more.
From this state it can wake up by receiving an <ENQ> (ASCII code 5) character from the
other side, and the instrument will immediately respond an <ACK> (ASCII code 6). From this
point the instrument will send data if it is ready for transmission.
The communication is based on packages. There are 5 package types:
• INIT package: Device identification, software version, current date and time.
• DATA package: Sample and patient information, measured parameters, and markers.
• RBC package: Sample information, RBC histogram.
• WBC package: Sample information, WBC histogram.
• PLT package: Sample information, PLT histogram.
The communication sequence is always started with an INIT package. If the link is successful,
the instrument will send DATA package, and the receiver can request RBC, WBC and PLT
packages at acknowledge.
Special characters used in the communication:
Character ASCII code
<SOH> 1
<STX> 2
<ETX> 3
<EOT> 4
<ENQ> 5
<ACK> 6
<HT> 9
<LF> 10
<NAK> 21
<SPACE> 32
Abacus/Arcus Service Manual 59
Format of Packages Sent by Abacus/Arcus
The packages sent by Abacus/Arcus are always between a <SOH> and <EOT> character,
and they consist of header, data and tail. The header consists of a package identifier and a
package type descriptor. The tail includes the checksum. Typical format:
<SOH>MID CMD<STX>MESSAGE<ETX>CHKSUM<EOT>
MID: Message ID, one capital letter between ’A’ and ’Z’
CMD: Command, one capital letter, package type descriptor
• ’I’ for INIT;
• ’D’ for DATA;
• ’R’ for RBC;
• ’W’ for WBC;
• ’P’ for PLT.
MESSAGE: the message consists of ASCII characters (between 32..128)
CHKSUM: two hexadecimal digits of a one-byte checksum which contains
the lower byte of the sum of characters between the <SOH>
and <ETX> (incl. those, too).
Format of Acknowledge of the Receiver
The receiver must acknowledge transmission by the following message:
<ACK>CMD MID
CMD: the type of the next package to send – this makes possible to a
request for histograms. If no more packages are required,
<SPACE> should be sent.
MID: the identifier of the package that acknowledged by this
message.
If receiving of the message was not successful, <NAK> should be sent, and Abacus/Arcus
will repeat the last package.
The receiver has approx. 1 second to reply, otherwise Abacus/Arcus will repeat the last
transmission, twice automatically. But if still no response after 3 trials, Abacus/Arcus will not
start to communicate any more, even if there is data to send (see General Description).
Detailed Description of Packages
The packages sent by Abacus/Arcus are placed between a header and a tail. There are 3
main types of them: INIT, DATA and histogram packages. The histogram package can be:
RBC, WBC, and PLT. Their format is the same, the type descriptor differs only.
INIT package
Abacus/Arcus sends the general identifiers by this package during initiation of a
communication:
DEVICE<HT>VERSION<HT>DATE<HT>TIME
DEVICE: device identifier
VERSION: version of the software, e.g. „1.7”
DATE: date in YYYYMMDD format
TIME: time in HHMMSS format
Abacus/Arcus Service Manual 60
DATA package
This package contains sample and patient data, the measured parameters and the markers
of histograms. One data element consists of two items: name and value, which are
separated by a <HT> character, and closed by <LF>.
Important! SNO, DATE, TIME, SID and PID fields will always be present in this order,
but other fields may be omitted.

Let us suppose that the receiver was not ready to receive when Abacus/Arcus was switched
on, therefore the instrument is not starting a communication.
Receiver sends that it is ready to receive now, Abacus/Arcus sends acknowledge.
