ADDER MAN-000023 Multi-Viewer Switch API
Product Information
The Adder Multi-Viewer Switch API is a device that allows remote control of the AVS-1124 and CCS-MV4224 Adder Multi-Viewer Switches using RS-232. This device can be connected to a controlling device such as a PC, allowing users to perform actions that can only be done using the front panel or hotkeys remotely.
The device sends Keep-Alive events every five seconds to communicate the current configuration, and the interval time of these events can be changed using the #ANATA command followed by a time period operand in units of 0.1 second.
Product Usage Instructions
To use the Adder Multi-Viewer Switch API, follow these steps:
- Connect a controlling device to the switch’s RCU port using a suitable RS232 cable with an RJ12 connector.
- If the controlling device does not have an RS232 port, use a USB or Ethernet adapter.
- Install PuTTY on the remote computer.
- Connect a serial cable from the PC’s USB port to the switch’s RCU port.
- Run the PuTTY utility.
- Configure the Serial, Terminal, and Session settings as per figures 1 to 3 in the user manual (MAN-000023).
- Type the appropriate command to perform an action on the switch. The command structure is comprised of four fields:
-
ANATL
- Command Type (e.g. F3, 4, F)
- Channel Number (1-4)
- End of Command (END)
Example commands include:
-
ANATL F3 END – loads preset #3
-
ANATL 4 END – switches to channel #4
-
ANATL F END – maximizes active channel to full screen
The general format of the command to move and resize a window is:
ANATL <Window Top Left X Location (0 to
100%)> <Window Top Left Y Location (0 to 100%)> <Window X Extent as Percentage
of Total X Width>
Where:
-
is a translation of the keyboard hotkey listed in an Appendix of the Multi-Viewer User Manual (MAN-000007). -
is the switch’s channel number (1-4).
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
- Install PuTTY on the remote computer.
- Connect a serial cable from the PC’s USB port to the switch’s RCU port.
- Run the PuTTY utility.
- Configure the Serial, Terminal and Session settings, as per figures 1 to 3
Figure 1: PuTTY Serial Settings
Figure 2: PuTTY Terminal Settings
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:
-
There is a space between each field
-
The pre-amble is either #ANATL or #ANATR, where:
-
ANATL equals the key sequence Left CTRL | Left CTRL
-
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 |
| Switch to channel #4 | Left Ctrl | Left Ctrl |
| Maximize active channel to full screen | Left Ctrl | Left Ctrl |
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
Where:
- Window top left X location (0 to 100%)
- Window top left Y location (0 to 100%)
- Window X extent as percentage of total X width
- Window Y extent as percentage of total Y height
- X offset (the location of the window compared to the full image size when bigger).
- Y offset (the location of the window compared to the full image size when bigger).
- X scaling as a percentage
- Y scaling as a precentage
| 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 |
