4.2.3 Structu re of Messages

The messages consists out of a 

RCS

-independent and a 

RCS

-dependent layer. The 

RCS

-independent

parts are interpreted the same by all types of devices. The 

RCS

-dependent parts contain specific com-

mands for a certain type of 

RCM

: the message body.

A message has the following structure:

<STX> <TYPE> <ADDRH> <ADDRL> <Body> <CHKH> <CHKL> <ETX>

These are the elements of a message in detail:

STX

The control character 

STX

 (

Ctrl-B

) is the beginning of a

message. All previously received characters are ignored and
are not sent on. (

Ctrl-B

 is displayed as   in most terminal

applications.)

<TYPE>

1 byte ASCII
declares the type of class of addressed 

RCS

.

<ADDRH><ADDRL>

2 bytes ASCII decimal
addresses the n-th 

RCS

 within a class of the specified type.

<Body>

type-dependent part of the message, e. g. a command

<CHKH><CHKL>

2 bytes ASCII decimal
is the sum over all fields from 

<TYPE>

 to 

<Body>

. The

checksum is evaluated by the recipient.

ETX

The control character 

ETX

 (

Ctrl-C

)is the end of a message.

(

Ctrl-C

 is displayed as   in most terminal applications.)

Table 4-2

Four different types of messages are used:

commands

RCM

 sends command messages to a 

RCS

.

acknowledge

RCS

 sends responses to the 

RCM

 after having executed the command

responses

RCS

 sends responses to the 

RCM

 on request.

interrupts

RCS

 reports errors to the 

RCM

 without request.

Table 4-3

4.2.4 Acknow ledge

The acknowledge is composed of the 

command

 the RCS has received and executed and the internal

Status Register

.

An acknowledge has the following structure:

<STX><TYPE><ADDRH><ADDRL><Body><STATH><STATL><CHKH> <CHKL><ETX>

These are the elements of an acknowledge in detail:

STX

The control character 

STX

 (

Ctrl-B

) is the beginning of a message.

All previously received characters are ignored and are not sent on.
(

Ctrl-B

 is displayed as   in most terminal applications.)

<TYPE>

1 byte ASCII
declares the type of class of addressed 

RCS

.

<ADDRH><ADDRL>

2 bytes ASCII decimal
addresses the n-th 

RCS

 within a class of the specified type.

<Body>

type-dependent part of the message, e. g. a command

<STATH><STATL>

2 bytes Hexa decimal
information about the internal 

Status Register

<CHKH><CHKL>

2 bytes ASCII decimal
is the sum over all fields from 

<TYPE>

 to 

<STATL>

. The checksum

is evaluated by the 

Remote Control Master

.

ETX

The control character 

ETX

 (

Ctrl-C

)is the end of a message. (

Ctrl-

C

 is displayed as   in most terminal applications.)
