Introduction

This guide explains how to use RS-232 to remotely control an Adder Multi-Viewer switch (AVS-1124,

CCS-MV4224).

To control a switch using RS232, the user needs to connect a controlling device to the switch’s RCU port.

The controlling device can be a PC or any custom device with RS-232 capability.

Remote controlling means performing actions that users could otherwise do only using the front panel or

hotkeys, including:

•Switching channels

•Audio hold

•Selecting a screen preset layout

Installation

This procedure shows how to connect a switch to a remote-control device. A suitable RS232 cable will be

required with an RJ12 connector to plug into the RCU port with the pinout shown below:

Pinout for the RDU port:

•Pin 1: 5V

•Pin 2: Not connected

•Pin 3: Not Connected

•Pin 4: GND

•Pin 5: RX

•Pin 6: TX

Few modern PCs have an RS232 port, so it may be necessary to use a USB or Ethernet adapter.

Operation

Configuring example using the PuTTY open-source serial console utility. This procedure demonstrates

how to switch channels via RS-232 using a remote control Windows PC.

Pre-configuration

1. Install PuTTY on the remote computer.

2. Connect a serial cable from the PC’s USB port to the switch’s RCU port.

3. Run the PuTTY utility.

4. Configure the Serial, Terminal and Session settings, as per figures 1 to 3

Figure 3: PuTTY Session Settings

Note: At this point, the device starts sending Keep-Alive events, every five seconds.

Keep-Alive events are transmitted by the switch periodically to communicate the current configuration.

For example, to switch to Channel 4, the user types: #AFP_ALIVE F7

Then, every five seconds, the device sends the following keep-alive event: 00@alive fffffff7 as shown in

Figure 4.

Figure 4: Keep-Alive Events

The interval time of keep-alive events can be changed, using the #ANATA command followed by a time

period operand in units of 0.1 second. Thus:

•#ANATA 1 gives an interval of 0.1 seconds

•#ANATA 30 gives an interval of 3 seconds

Command Structure

The command structure is comprised of the following 4 fields:

Multi-Viewer Switch API

MAN-000023 Page 5

<pre-amble> <command> <operand1> <operand2>

Where:

•There is a space between each field

•The pre-amble is either #ANATL or #ANATR, where:

o#ANATL equals the key sequence Left CTRL | Left CTRL

o#ANATR equals the key sequence Right CTRL | Right CTRL

•Commands require 0, 1 or 2 operands

•Command success: Upon successful command execution, the device returns the output:

command + OK

•Command failure: Upon failure, the device returns the output: command + Error Message

•To initiate a new serial connection, enter #ANATF 1

Command List

The command is a translation of the keyboard hotkey listed in an Appendix of the Multi-Viewer User

Manual (MAN-000007). Example translations are:

Description

Hotkey

API Command

Load preset #3

Left Ctrl | Left Ctrl | F3

#ANATL F3

Switch to channel #4

Left Ctrl | Left Ctrl | 4

#ANATL 4

Maximize active channel

to full screen

Left Ctrl | Left Ctrl | F

#ANATL F

Figure 5: Example commands

The most common commands are likely to be loading a preset and positioning and resizing windows on

the display. The general format of the command to move and resize a window is:

#ANATL F11 END <Channel> <Operation> <Location>

Where:

<Channel> is 1 to 4

<Operation> is:

1. Window top left X location (0 to 100%)

2. Window top left Y location (0 to 100%)

3. Window X extent as percentage of total X width

4. Window Y extent as percentage of total Y height

5. X offset (the location of the window compared to the full image size when bigger).

6. Y offset (the location of the window compared to the full image size when bigger).

7. X scaling as a percentage

8. Y scaling as a precentage

<Percent> is a 4 digit number in increments of 0.01%

Note that where dual monitors are used in Extend mode, the percentages relate to the total display size.

For example, to set the window for channel 1 to occupy the 4th quadrant:

Description

API Command

Set the window top left X position at half display

#ANATL F11 END 1 1 5000

Set the window top left X position at half display

#ANATL F11 END 1 2 5000

Set window X extent to half screen

#ANATL F11 END 1 3 5000

Set window Y extent to half screen

#ANATL F11 END 1 4 5000

Figure 6: Set Channel 1 to 4th quadrant (single monitor)

Note that the commands change slightly when using dual side by side monitors:

Description

API Command

Set the window top left X position at half display

#ANATL F11 END 1 1 2500

Set the window top left X position at half display

#ANATL F11 END 1 2 5000

Set window X extent to half screen

#ANATL F11 END 1 3 2500

Set window Y extent to half screen

#ANATL F11 END 1 4 5000

Figure 7: Set Channel 1 to 4th quadrant of left monitor

There is one command that doesn’t adhere to the aforementioned pattern, Audio Hold. To toggle the

audio hold button, enter the command:
