DIAP

1.1 Introduction

This document defines the DIAP for new patient monitor external data communication design.

1.2 DIAP

The DIAP was designed to be simple, yet extensible for new features without compromising programs
written by third parties.

1.2.1 Connection Type

The DIAP is a point-to-point, hierarchical (one or more into one host) protocol. All communications are
initiated by the host. No common access media types, including serial multi-point connections, are
supported.

It is a request/reply, non-continuous protocol. Only numeric data (no waveforms) are supported.

1.2.2 Physical Protocol

The physical interface for the DIAP is asynchronous serial, with a baud rate of 9600 and 19200, 8 bits, 1
stop bit, no parity.

1.2.3 Session Protocol

The messages must be/are encapsulated as follows:

First Character Last Character

Command

HEADER <

DIAP Communication Protocol Service Manual 0070-10-0307 1-1

Reply

> CRC LF

DIAP

 All Commands are case-insensitive ASCII.

 All Replies are mixed case as indicated in next section.

 Timeout: No reply for 10 seconds.

 Maximum message size for Commands is 255 total bytes.

 Maximum message size for Replies is 511 bytes.

Where:

Item Description Type Length

- it is always 001 to 999 for a central monitor

< , > are delimiter characters literal ASCII string 1, 1

literal ASCII character
+ ASCII decimal numeric

4+3

CRC is a cyclical redundancy check as described in the

section beginning on page 2-1.

LF is an ASCII line feed character. literal ASCII character 1

1.2.4 Command/Reply Legend

This is the legend to the Command/Reply list. It indicates how the arguments for the Commands and
Replies are defined. See “Commands and Replies”(section 1.3).

 Items designated as ‘ASCII decimal numeric’ are padded with leading (left) zeros.

 Items designated as ‘ASCII hex numeric’ are padded with leading (left) zeros.

 Items designated as ‘literal ASCII string’ are padded with trailing (right) spaces.

 Items designated as ‘ASCII string’ are padded with trailing (right) spaces.

 Items designated as ‘ASCII string’ will be truncated by the monitor/central as necessary.

 Items designated as ‘ASCII string’ may contain A-Z, a-z, 0-9, comma, period, dash, space, question

mark.

1.3 Commands and Replies

The following is a list of alternating Commands and Replies. They are encapsulated in the format
above. There are no space characters within the Commands or Replies - they are indicated in the

table for clarity only.

 Multiple Commands may be sent in one message; they must be separated by semi-colons (‘;’); the

Replies will be returned in a single message separated by semi-colons. Having replies returned as

a single message insures that the information in the replies are all synchronized with respect to one
another (atomic transaction).

Example:

Command:

DIAPØØØ<t1;t2;deltaT>

Reply:

DIAPØØØ<t1=42;t2=39;deltaT=3>

The value for deltaT will reflect what the values were for t1 and t2 at the time the message was
received.

Command:

DIAPØØØ<t1>

Reply:

DIAPØØØ<t1=42>

Command:

DIAPØØØ<t2>

Reply:

DIAPØØØ<t2=39>

Command:

DIAPØØØ<deltaT> (meanwhile, t1 changed from 42 to 40)

Reply:

DIAPØØØ<deltaT=1>

1-6 070-10-0307 DIAP Communication Protocol Service Manual

DIAP

The value of deltaT reflects the most current temperature values and not necessarily those from
previous commands.

 If a particular imbedded Command is invalid, the particular Reply will be “UNSUPPORTED

FEATURE”.

Example

Command:

DIAPØØØ<ecgHR;p3>

Reply:

DIAPØØØ<ecgHR=Ø81;p3=UNSUPPORTED FEATURE>

 Command keywords ending with a colon (:) will control the DIAP slave.

Example

Command:

DIAPØØ1<patient:A1Ø ,ICU3,John Doe ,>

Reply:

DIAPØØ1<patient=A1Ø ,ICU3,John Doe ,>

-Indicating that the controlling Command has been accepted by the DIAP Slave.

NOTE: There are 24 trailing spaces after the name “John Doe”, for a

total of 32 characters.

 The commands that are supported by a product are indicated by a checkmark () in the product’s

column(s). All other commands will receive the UNSUPPORTED FEATURE reply.

 Protocol changes that affect Command or Reply or Message formats will cause pVersion to be

changed; changes that affect whether a feature is supported on a given product will cause

pRevision to change for that product.

1.4 Error Handling

1.4.1 Field Level Errors

Invalid data fields in replies are represented by two, three, or more dashes (— or —-, etc.), based on
the expected value length.

1.4.2 Command Level Errors

If an error occurs, an error reply is returned to the host in place of the normal reply.

These Command Level Errors are indicated below (literal ASCII string, prefaced with a %):

Error Description

UNABLE TO CONNECT The monitor cannot respond.

NO OPEN DELIMITER The monitor could not find the character ‘<‘ (open delimiter) in the message

NO CLOSE DELIMITER The monitor could not find the character ‘>’ (close delimiter) in the message

NO LINE FEED The monitor could not find the linefeed character in the message received,

INVALID CRC CHAR The monitor detected a non-hexadecimal CRC character (syntax error).

UNDEFINED ERROR The monitor detected an undefinable syntax error.

RESPONSE TOO LARGE In a multiple command message, the response is greater than the maximum

REQUEST CORRUPT The monitor detected an invalid CRC.

CHANNEL OUT OF RANGE The central monitor could not reply because the channel number requested is

BAD MSG HEADER The message header did not contain ‘‘DIAP’’ as the first four characters

COMMAND TO LARGE The message size exceeded the maximum of 255

IBP LABEL NOT APPLIED The monitor cannot return a value because the requested IBP label has not

A.2 CRC Test Program

The following program can be used to test the above:

#include <stdio.h>
int main(void) {
unsigned char buffer [] = {0, 0, 0, 0, 0, 0x77, 0xCF};
printf(“CRC(Expected 0x73F3) = 0x%04X\n”, Crc(0x0, 7, buffer));
return(0);
}

NOTE: For the example above, the value for the last CRC parameter

should be initalized to zero (0).

B.1 DIAP Modem Support (Optional)

B.1.1 Overview

B.1.2 Physical Implementation

Appendix B

Optional support for a modem attached to a DIAP Slave is described here.

A standard external modem is connected to the DIAP Slave, such as a Passport, Point of View, VISA,
etc. The same modem type is connected to a DIAP Master, such as a personal computer, workstation,
minicomputer, etc. A public telephone switching system connects the modems.

B.1.3 DIAP Slave Requirements

The Mindray equipment must have the following additions made to implement DIAP Modem Support:

 Configuration Dialog for Modem Connected (yes/no choice, default no)

 Configuration Dialog for Modem Speaker On (yes/no choice, default no)

 User Dialog for Reset Modem (button)

Upon initialization, the DIAP Slave UART is set per section 1.2. The modem initialization string is them

sent (section Error! Reference source not found.). The modem initialization string is re-sent anytime

the Reset Modem button is depressed.

B.1.4 DIAP Slave Supported Modems

The DIAP Slave shall support the following V.32-compliant or higher modems:

 Hayes Accura 144

B.1.5 DIAP Slave Modem Initialization Strings

The DIAP Slave communicates with the modem as follows:

NOTE: The above assumes that the modem is new or reset to default

factory configuration.

NOTE: If the configuration Modem Speaker On = ‘yes’, then do not send

the ATM0 command above.

B.1.6 DIAP Master Requirements

The Master computer must initialize the local serial port (setting communications parameters per
section 2.2) and initialize the locally- attached modem (including modem reset, setting up off-hook and
telephone dialing to the DIAP Slave modem). It also configures the modem in a manner similar to the
DIAP Slave modem (XON/XOFF flow control).

B.1.7 DIAP Master Supported Modems

The DIAP Master shall support any V.32-complaint or higher modem.
