MDP 500 (G6) Preamplifier Processor RS-232 command set

Version MDP500-4.2, (applies to S/N 6001 and thereafter) 13th August 2002

Technical specification

9600bps , 8 data bits, one stop bit, no parity, binary transmission, no flow control.

Important: An external Baud Rate Converter is required in order to use the RS-232 interface. It is needed because the MDP 500’s internal clock is not related to the standard RS-232 data rates. Baud Rate Converters are available from Myryad Systems.

[The MDP 500’s “direct” baud rate is 11000bps. If a controller is used which can send and receive directly at this rate, then no separate baud rate converter is necessary.]

RS-232 baud rate converter and connectors

Baud Rate Converter: This is a small self-contained module which is fitted between the MDP 500 and the system controller, dimensions approximately 63x54x16mm. It has 25-pin “D” i/o connections. The male connector goes towards the MDP 500 and the female towards the system controller. Myryad supplies each baud rate converter with two 25-to-9 pin “D” adapters so that conventional 9 pin serial interface cables can be used.

The RS-232 pin connections are as follows:

Input commands

Single byte user commands

The following user input commands are all single bytes sent to the MDP 500’s RS-232 port. They create various output data depending on the system status, so a comprehensive output data feedback can’t be given.

Each user input command must be preceded by the “RS_ENABLE _CONTROL” command which is a string of four bytes: <224><82><83><33>

Note: All command and data bytes are given in decimal format.

Multi-byte User Commands

The following commands need two or more bytes, in the form: <command><data1>[<data2>]…….

Each of these commands must be preceded by the “RS_ENABLE _CONTROL” command in the same way as the single byte commands.

For example, the Master volume may be set directly using the command UI_SET_VOLUME.

The format of this command is: <224><82><83><33> (RS_ENABLE _CONTROL as before)

followed by: <180><data>

where <data> = 10…100 where 10 = -90dB, 100 = 0dB

(0dB is maximum direct setting for reasons of safety)

Output data

The following data (in the table below) are sent out to the RS-232 port whenever the status of the current parameter or function is changed. The output data consist of at least three bytes: <command> <data> <EOT>. For example when the Master Volume is changed to –25dB the following three bytes are sent out: 225 75 255.

Alternatively, the full set of output data may be requested without changing any parameter by using the RS_QUERY_SYSTEM_STATUS command. The protocol for this command is to send the single byte <227>. The MDP 500 will then return two header bytes <223><255> followed by all of the output data items listed below in sequence. The communication will thus be:

Controller sends byte <227> to MDP

MDP returns with:

<223> <255> // header

<225> <vol> <255> // RS_VOLUME

<226> <mute> <255> // RS_MUTE

……

……

<249> <TV-system> <255> // RS_TV_SYSTEM

Within this string of data there will also be some items of “null” data. For example null data “250” will appear as:

<250> <255>

Appendix 1 – RS_STORE_EEPROM and RS_READ_EEPROM

This appendix gives further information about RS_STORE_EEPROM and RS_READ_EEPROM commands.

RS_STORE_EEPROM is used to store one byte to the EEPROM, where all user settings are stored. This commands allows setup values to be configured during installation. The command is not intended to change any values during normal operation, since the values are only stored to the EEPROM and are not automatically updated to the system. Some changes may not become effective until re-boot.

The address is calculated by the following formula:

address = MSB address * 256 + LSB address

The table below has both MSB and LSB addresses already calculated

EXAMPLE

The analog sensitivity of the Source2 is set to –3dB:

– first send the RS_ENABLE_CONTROL <224><82><83><33>

– send the RS_STORE_EEPROM command <230>

– send the address <3><81>

– send the sensitivity <82>
