Model 2200/3000/4000 Protocols

Introduction

General Description

The Þrst four sections of this document describe the communications protocol

supported by the Model 2200, 3000, and 4000 Switchers for use by editors. This

protocol is called the Òeditor protocolÓ or Òeditor interfaceÓ in this document. This

protocol is used by Grass Valley Sabre and Super Edit Editors. The information is

provided in this manual for use by other vendors wishing to interface their editors

to these Grass Valley switchers.

Detailed on the following pages are the protocols, data formats, and system timing

requirements for commands exchanged between an editor and the Model 2200,

3000, and 4000 Production Switchers. Although the protocol is common for all of

these switcher models, the different models do differ in their capabilities. The

detailed capabilities of each model are described in the pertinent Operation

manual. However, in general, the switchers do for the most part provide the same

functionality. From the perspective of an editor, the major differences between the

models are the number of M/Es and whether or not the switcher has a DSK and

PGM/PST bus.

Manual Contents

In addition, Section 5 of this manual describes the Control-Point Language (CPL)

protocol used with the Grass Valley Krystal digital picture manipulator (DPM).

This manual has been revised to incorporate changes made in the software since

its initial release.

Section 1 Ñ introduces this manual and the switcher communications protocol.

Section 2 Ñ describes the editor serial protocol.

Section 3 Ñ lists and explains the speciÞc commands used to control the switcher

for Version 5.1 and later, and for Version 5.0 and earlier.

Section 4 Ñ lists and explains the new parameter-based command set (PBCS) for

reading, setting, and trimming the switcher state directly, introduced with

Version 5.1.

Section 5 Ñexplains the effect recall and run (including the switcherÕs run lever

arm), control of switcher aux busses by the DPM when used as input selectors,

and on air tally involving the DPM with Version 5.1.

System Performance

The Editor Interface can continuously receive and process a steady stream of

commands. Although all commands are received, some time may be required to

act upon these commands. For example, transferring E-MEM

the editor and the switcher may take several seconds to complete.

Any Read Command has a switcher latency of 2 Þelds; that is, the response will

occur 2 Þelds after the Read Command has been received.

All other commands except E-MEM and ConÞguration Transfer Commands have

a switcher latency of 10 Þelds.

E-MEM and ConÞguration Transfer Commands have no Þxed latency in the

switcher. The transfer will take place as soon as all higher-level commands have

been executed.

The transfer commands have a one second timeout imposed on the time between

each packet transmission.

Editor Protocol

Serial Communications

This section describes the communications protocol and its error handling.

A Video Editing System uses the switcher editor port to exercise real-time control

over the switcher's functions. The editor is really an external computer that can

input and output functions. Such functions select crosspoints, perform auto

transitions, or perform E-MEM (Effects Memory) register recalls, to name just a

few possibilities. Refer to the appropriate switcher Operation manual for

deÞnitions and explanations of the switcher functions and features.

Editor Protocol Access

The 2200/3000/4000 Editor Protocol is based upon, but not identical to, the

proposed SMPTE (Society of Motion Picture and Television Engineers) Digital

Control Interface, which establishes a means for the orderly ßow of data over a

serial bus.

The major components of the protocol are shown in Figure 2-1 and discussed in

the following paragraphs.

Section 2 Ð Editor Protocol

Break Character

The main component of the Editor Interface protocol is a 1-1/2 character-length

Òbreak.Ó A break consists of a spacing or logical low (0) condition on the serial bus

(see Figure 2-2) followed by a minimum of two bit-times of marking (logic 1)

condition. The Bus Controller (editor) transmits a break to the switcher,

forewarning of an impending message.

The break forces all tributaries , or listeners (such as the switcherÕs editor port),

from the ÒIdleÓ state into the ÒActiveÓ state. A break can be sent only by the Edit

Controller. When the switcher receives the break, it ceases all bus

communications, resets any communication error condition, and prepares to

receive an address.

Section 2 Ð Editor Protocol

Address Byte

Once the break has been received, the Editor Interface advances to the active state

and begins expecting a one-byte address. The switcher will respond to the

switcher address 30H (Hexadecimal), when transmitted by the Edit controller.

After receiving the address, the Editor Interface accepts command/message block

transmissions containing commands, data requests, and other data directed

toward the switcher. As long as communication errors do not occur, the Editor

Interface can skip the break/address sequence during the remainder of the

transmissions. Command/message blocks can be sent repeatedly, one after

another, without break interruptions.

The address is one byte long and directed to a speciÞc tributary. If the received

address matches the tributaryÕs assigned address, the tributary advances to the

Selected state and awaits instructions. The address of the switcher is Þxed as 30H.

In response to the address, the 3000 transmits an acknowledgment byte of 84H to

the controller, indicating the change in status to the ÒSelectedÓ State. If an address

of 31H is received, the switcher transmits an acknowledgment byte of 84H to the

controller, but stays in the ÒActiveÓ State. If the address does not match, the

tributary drops off the bus (goes Idle) and awaits another break.

Note that when the switcher receives a break without an address as a result of an

Editor Interface reset (

Interface), it returns the 84H acknowledgment byte to the controller. If the edit

controller sends subsequent breaks to the switcher (when no Editor Interface reset

has occurred), the switcher responds by sending 85H followed by 84H.

Command/Message Block Structure

In the Selected state, the Editor Interface receives command/message blocks that

direct switcher operations. The basic message structure is shown in Figure 2-4.

Command Code Byte

Maximum Size

255 Bytes

Figure 2-4. Message Structure

The maximum length of a message is 255 bytes plus the byte count byte. At a baud

rate of 38,400, the maximum length command/message takes more than 4 Þelds to

complete.

The Editor Interface can handle data continuously, receiving a contiguous stream

of command/message blocks. Such an ability enables multiple switcher

operations to be performed without constant cycling through the break/address

sequence. Responses (handshakes or read data) are returned in the same order as

the command/message blocks are received.

The command/message block can range in size from two to 256 bytes. The Þrst

byte of the block contains the byte count. A byte count consists of the total number

of subsequent bytes in the block; valid byte count values range from 01H to FFH

(1 to 255). After receiving a valid byte count (01H to FFH) and the proper number

of data bytes (1 to 255), the Model 3000 executes the command.

Effects Address Byte

The second byte of the command/message block is the effects address byte,

typically referred to as EX. This byte identiÞes the desired Òeffect bankÓ within the

switcher where the associated command will go. Valid Effects Addresses for each

command are speciÞed in Section 3.

2-5

Section 2 Ð Editor Protocol

Command Code Byte

The command code is the third byte of the command/message block. Command

codes fall into two broad categories: read commands and write commands. Only

one command is allowed in any command/message block. Likewise, only one

response is embedded in any command/message block.

Read Commands

Read commands interrogate the status of the speciÞed operational parameter of

the switcher. When the editor issues a read command/message block, the

switcher responds by sending the current status of the requested operational

parameter(s) back to the editor. This status information is returned in the format of

the write command/message block. By echoing the write format, the editor can

later send responses to a read command to the switcher and cause execution of

that function.

Write Commands

Write commands are used by the editor to change operational parameter(s) or

initiate a function within the switcher.

2-6

Status and Data Replies

The editor interface does not respond to the controlling device upon the receipt of

each and every character. It does respond to the last character of any complete

message. The Þrst character of any message is the Òbyte countÓ byte, specifying

the number of message bytes that are to follow. A message transmission is

complete when the total number of characters speciÞed by that byte plus that byte

itself have been received.

There are Þve possible replies in response to the complete message as outlined in

Table 2-1.

Response Type Message In Response To:

Acknowledge 0x84 Valid Select or Poll Address

Status and Data Replies

Table 2-1. Possible Command Responses

Negative Acknowledge

Protocol Error 0x01 0x40 Invalid Protocol Message (Read or Write);

Command Accepted 0x01 0x80 Valid Protocol “Write” Message Data Message Write Message

Once the interface is placed into the Select State, the most common response is one

of the two-byte status reply messages. The second byte of this message is the

response to the command. The upper two bits signify whether the command was

accepted or not as illustrated in the following Þgure:

Timeout Error in Select State

Valid Protocol “Read” Message

(length varies)

7 6 5 4 3 2 1 0

X X 0 0 0 0 0 0

1 = Protocol Error 1 = Command Accepted

Note that these bits are mutually exclusive; that is, both may not be set in the same

message.

If Command Accept is true, the message was forwarded to its handler for

execution. However, this status reply only means that the command was received

with no transmission errors and passed the protocol validation test (byte count

and command code) for the message structure itself. The message may still not be

executed by the Switcher for failures on the Protocol Command level.

2-7

Section 2 Ð Editor Protocol

Error Detection

Transmission Errors

Error detection is a normal part of the communication process. For this Protocol

Interface, error detection and reporting is limited to problems that occur at the

transmission and reception level of communication. These type of errors fall into

two basic categories, line and time-out errors.

Line errors include three speciÞc types of errors that may occur with each

character transmission and reception.

These errors occur when the Serial Data Word becomes corrupted.

Parity error

Framing error

Data Overrun error

Time-out errors occur when too much time elapses between the reception of

characters during a message transmission.

When the Editor Interface detects communication errors, it responds with a

negative acknowledge of 85H and then aborts all communications. Any remaining

un-executed commands are discarded after the error indication occurs and the

Interface is forced back into the Idle state. Refer to Figure 2-2 on page 2-2 and Table

2-1 for details of the detection and corresponding response to each error type.

In order to resume communications, the Editor must transmit a break/address

sequence to return the channel to the Select state. If the Editor Interface does not

receive a valid tributary or poll address following the break, it falls back into the

Idle state without transmitting the 85H Negative Acknowledge byte. Line errors

that occur during an attempt to send and receive the address byte still result in a

Negative Acknowledge byte being sent back to the Editor.

2-8

Protocol Errors

Errors can occur on the Protocol level itself; that is, the message may be received

okay, but may not actually be executed due to problems with content or context.

The only error that will be reported to the Editor as a Protocol Error (01 40) occurs

if either the byte count or the command code fail the validation test when a

complete message is received.

All other protocol errors go unreported back to the Editor. The only response the

Editor receives to these messages is a Command Accepted message. The handler,

when it uncovers a problem, will simply throw the message away and the user

will see no change to the operation of the Switcher.

Some possible causes of unreported protocol errors are listed as follows:

Content Errors:

¥ ¥

Invalid effects address.

Invalid data (register number, analog value, etc.)

Error Detection

Context Errors:

Command is Òpanel-centricÓ and may only be executed when the Switcher is in a specific state.

Introduction

Editor Interface Commands

This section details the Switcher Editor Interface commands for Model 2200, 3000,

and 4000 Switchers.

References to pushbuttons are shown in capital letters, using the legends as they

appear on a Control Panel. Control Panel section names are shown in initial

capitals.

NOTE:

by the notation Òdecimal.Ó

All values within the tables are hexadecimal unless otherwise indicated

Editor Interface Commands

This section describes the traditional editor command set which bears a family

resemblance to earlier generation Grass Valley switchers such as the Model 200

and the Model 300.

Editor interface commands are detailed in tables presented on the following

pages. Addresses, byte counts, important names, and supporting details are listed

for each command.

With Software Version 5.1, new commands are added and some existing

commands enhanced. This is clearly marked for each command. Also, with

Version 5.1, Grass Valley has developed a new parameter-based command set

(PBCS) for advanced editing control. PBCS allows setting, trimming, and reading

of all internal switcher parameters completely independent of panel operations.

This is described in Section 4.
