1 RS-232 Protocol, Programming Commands, Example

SWITCHERS

IBM PIN No.	MX2456RM
	Contact
2	TX
3	RX
5	GND

Connection of IBM-PC 9-pin D to the MX2456RM Terminal Block

Port setting preferences for the control system or computer being used to control the switcher should be set as follows:

BAUD RATE (Bits per second)	9600
Data bits	8
Parity	None
Stop Bits	1

7.2.1 RS-232 PROTOCOL

The RS-232 protocol for the MX2456RM Switcher uses a simple ASCII character format.

1.Square brackets “[“ & “]” are part of the command.

2.Use uppercase letters for all commands.

3.Make sure that the transmit pin of the control system is connected to the receive pin of the switcher and connection done as per Table 5.

4.Make sure that there is a delay of 50 ms between two consecutive commands.

The factory default settings is 9600 baud, 8 bits, 1 stop, and no parity. There is no software or hardware flow control implemented.

The MX2456RM Switcher requires 50ms of processing time after each command is sent. So, please keep a 50ms delay between two consecutive commands.

The RS-232 input has a 16-character buffer and will not execute any command longer than 16- characters. Any additional commands are ignored until the previous command is fully processed. After processing a valid command, an [OK] string will be returned if requested by the feedback command.

7.2.2 PROGRAMMING COMMANDS

NOTE:

These programming commands are used for programming the switcher; they should not be used as part of a program to operate the switcher. The programming setting changes done through these commands are stored in a

non-volatile memory. Typically, these commands can be issued 10,000 times before the memory needs to be replaced.

1.[# SW n1 n2 n3 n4 n5 n6] - Video Switch Input

This is the main command of the video input Switcher. The [# SW n1 n2 n3 n4 n5 n6] command contains all the information needed by the switcher to activate the video sources that are connected to the unit.

#= Switch number (No. from 1 to 9, Default = 0)

n1 = Video input number (No. from 0 to 6)

n2 = Break Away code (0 = On , 1 = OFF)

n3 = 0 (video key pressed)

n4 = Sync Delay (No. from 0 to 4)

n5 = Video Equalizer (Hexadecimal No. from 0 to F)

n6 = Audio Gain (Hexadecimal No. from 0 to F)

Example:

Sending the [8SW61040F] command will activate switcher module 8, video input number 6 and audio input 6. Since the break away code is 1, the zero (0) alerts the switcher that the video key was pressed. The video key has an interval of 4 (2 seconds). The video equalizer is OFF, and the maximum volume is F. Zero means OFF, and the default is 8 for normal volume or video.

2.[# SW n1 n2 n3 n4 n5 n6] - Audio Switch Input

This is the main command of the audio input switcher, which contains all the information
