PM1122‐INT Digital Interface Remote serial communication setup. In order to communicate with the PM1122 remote interface using a personal computer, you will have to set up your communication parameters correctly. You also need sufficient rights on your computer, so ask your system administrator for assistance if necessary. Serial cable specifications are also mentioned below.
Enter a name for the new connection, e.g. “PM1122” and click “OK”. As mentioned before, select your computer’s serial communication port. Under the pull‐down menu labeled “Connect Using” select your RS232 Com port, usually this is COM1.
To check the COM port name, look in Control Panel ‐> System ‐> Hardware ‐> Device Manager, you may need Administrator rights to access these pages, so ask your system administrator for assistance if necessary. Set the baudrate to 19200. You find this setting under the pull‐down menu labeled “Bits per second”. 19200 is the standard PM1122 interface baudrate, after connecting, you can change it to 2400, 4800, 9600 or 19200 using the commands as mentioned in the instruction set.
Next set Flow control to “none”. You find this setting under the pull‐down menu labeled “Flow control”. Click OK, normally Hyperterminal will connect automatically, you are ready to start the communication between PC and PM1122 interface.
Click on the telephone symbol to connect or disconnect to the PM1122‐INT. The bottom taskbar shows the connection status (connected / disconnected and the applied baudrate, databits, parity and stopbits). RS232 Cable Specifications. RS232 connection on the PM1122 interface: A straight through PC Serial Cable is used to communicate from the RS232 port to a third‐party controller such as a PC using Hyperterminal to the RS232 serial port on the PM1122INT unit.
Instruction set PM1122‐INT The PM1122‐INT can be controlled using RS‐232. Initial port settings are 19200 bits per second, 8 data bits, no parity, 1 stop bit and no flow control. The baud rate can be configured at different values, but this will be described later. For details on the serial cable and Terminal connection settings, refer to the PM1122‐INT interface serial communication setup document. Standard ASCII strings are used to control the PM1122‐INT so it’s possible to use Terminal software (e.g.
Controls: MSCLVL: Music Level MICLVL: Microphone Master Level SELECT: Input Source Selection MINMSCLVL: Minimum Music Level MAXMSCLVL: Maximum Music Level MINMICLVL: Minimum Microphone Level MAXMICLVL: Maximum Microphone Level To be complete, there is also a RESERVED_REG: which has no function but is kept for future possibilities Except for “SELECT”, all controls can be used with following commands: SET, GET, INC, DEC. “SELECT” can only be used with SET and GET.
RFKEY: Setting of the Easywave radio receiver only. PRESET: Presets can be stored, recalled and cleared. Commands are STR, RCL and CLR. With store and recall, first optional parameter is ZONE1 or ZONE2 and then the preset number between 1 and 64. With the CLR command, the only parameter is the preset number that needs to be cleared or “ALL”. ROTARYATSTART: When this is ON, the PM1122‐INT will load the preset selected by the wired rotary switch at startup (power on).
Easywave An optional Easywave receiver module can be mounted inside the PM1122‐INT. An eight button RF switch can be assigned to a zone of the PM1122. 4 buttons named A to D are used for selecting the source or to recall a preset. By default, these buttons are used to select source A to D. Next to that are an up and down button controlling the music level and finally the same 2 buttons controlling the microphone level.
Presets A preset is a set of stored values. These values are Music Level, Mic Level and Source Selection for zone 1 and/or zone 2. A preset can be stored, recalled or cleared. The only way to store a preset is by using the RS232 interface. A preset can be recalled using the same interface, using the contacts at the back side of the PM1122 or with an Easywave RF switch, if buttons A to D are assigned as preset selector knobs instead of source selectors, as described earlier.
PM1122 Control Panel In order to show you some of the RS‐232 remote control capabilities of PM1122 and PM1122‐INT, we have developped a custom application called PM1122 Control Panel. You will need a PC with a RS‐232 9 pin connector running on Windows 2000/XP and a standard straight through serial cable. Cable details can be found in the PM1122‐INT manual.
In the left menu tree, select “Connection”, the right part of the popup will show the connection details: Here you can select your computer’s COM port used for serial communication, and also select the baudrate, standard setting is 19200. If the “Connect on startup” is selected, the program will attempt to connect to the PM1122‐INT whenever you run it. If you make a change to one of the settings and wish to change the settings for future use, click the “Save Settings” button.
Here you can change the names of the four line sources connected to your PM1122 for easy identification. E.g. click in the SourceA field and type a new name for this source, such as tuner or CD player. Click on the “Save” button to save the names you assigned to the different sources. Now you can test the connection and functionality of the program. Go back to the main screen shown above. The power led indicator in the right top corner program will show the on/off status of the PM1122 pre‐amplifier.
We will now proceed to the next screen and show a few features not available on the pre‐amp’s front panel. Click the “Zones” tab in the top bar and select “Settings”. The mixer screen should look like this: Here you can set minimum and maximum levels for music and microphone in zone 1 and 2. Please note that the top sliders will move according to the min and max settings you specify here.
Here you can recall and save presets.There is a dropdown list showing presets numbered 1 to 12. If you select a preset, all settings specified in the preset will be loaded. In order to recall presets, you will have to save them first, so click the “Open Save dialog” button.
Here you can specify if the settings you make in the mixer and source select screen will be valid for zone 1 and/or zone 2. Simply set the levels and select the source in the mixer screen, click on one of the zone buttons under “What would you like to save” and give the preset a name if you wish. Next click the “Save preset” button.
