PM1122-INT DIGITAL INTERFACE REMOTE Overview The PM1122 Pre‐amp can be remote controlled by the PM1122‐INT. The PM1122‐INT can be controlled in 3 different ways: • Using RS‐232 • Using the contacts to recall presets • Using the optional RF module For control using the RS‐232 port, the PM1122‐INT accepts strings of ASCII characters to control and read settings of music level, microphone mix level and the input selector of both zones.

PM1122-INT DIGITAL INTERFACE REMOTE Instruction set PM1122INT The PM1122‐INT can be controlled using RS‐232. During power up, the current baudrate is shown on a LED bar. Please refer to “PM1122‐INT front panel description” at page 3 for the corresponding values. Initial port settings are 19200 bits per second, 8 data bits, no parity, 1 stop bit and no flow control. Only the baud rate can be configured at different values.
PM1122-INT DIGITAL INTERFACE REMOTE MICLVL: Microphone Master Level SELECT: Input Source Selection MINMSC: Minimum Music Level MAXMSC: Maximum Music Level MINMIC: Minimum Microphone Level MAXMIC: Maximum Microphone Level To be complete, there is also a RSRFFU: which has no function but is foreseen for future use Except for “SELECT”, all controls can be used with following commands: SET, GET, INC, DEC. “SELECT” can only be used with SET and GET.
PM1122-INT DIGITAL INTERFACE REMOTE INFO: Can only be used with GET and is only functional when VALFB is on. It will respond with a list of all controls and corresponding values. Next attributes are constants, which can only be used with GET SERIAL: HWVRSN: SWVRSN: Returns the Serial Number Returns the Hardware Version Number Returns the Software Version Number On the next page, you will find a table with all attributes and the possible commands.

PM1122-INT DIGITAL INTERFACE REMOTE Easywave An optional Easywave receiver module can be mounted inside the PM1122‐INT. To install this receiver, please carefully remove the top cover and slide the module in place like shown on the picture below. Once this module is installed, 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 configured to select source A to D.
PM1122-INT DIGITAL INTERFACE REMOTE command: “SET DBLCLICK OFF”. Please note that the click rate is quiet slow. This is due to the rate at which the RF telegrams are being sent. • Instead of selecting the music input source, the A, B, C and D buttons can be used to recall presets. Assigning these buttons to a preset can be done by the following instruction: “SET RFKEY ZONEx PRESET”. Please note this will take effect on all switches assigned to the same zone.
PM1122-INT DIGITAL INTERFACE REMOTE 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 or clear a preset is by using the RS232 interface.
PM1122-INT DIGITAL INTERFACE REMOTE Example one: by recalling preset 2, we want for zone 1: selector at source B, music level at maximum and mic mix level at minimum. For zone 2 we want the selector at source D and both music as mic mix level at 50%. First thing to do, is to set the controls (selector and levels) at the desired values.
PM1122-INT DIGITAL INTERFACE REMOTE Recall a preset using RS‐232 Recalling a preset with RS‐232 can be done with the RCL command. This will change the values to those of the corresponding memory location.
PM1122-INT DIGITAL INTERFACE REMOTE Before attempting to make adjustments to the settings, check the connection settings. In the upper taskbar, click “Tools”. A drop‐down selection menu will appear, select options, a popup screen will appear, it looks like this: In the left menu tree, select “Connection”, the right part of the popup will show the connection details: 14 WWW.APART-AUDIO.COM / INFO@APART-AUDIO.
PM1122-INT DIGITAL INTERFACE REMOTE Choose the COM port which is connected to the PM1122‐INT. In case you don’t know which port it is, please refer to chapter “Help, where is my COM port?” at page 24. The baudrate can be changed if necessary. If the “Connect on startup” is selected, the program will attempt to connect to the PM1122‐INT whenever started. These settings can be saved by pushing the “Save Settings” button. Next you can select the “Labels” in the left menu tree. The labels can be changed.
PM1122-INT DIGITAL INTERFACE REMOTE The main screen controls the source select (A to D), music level and microphone mix level of both zones. Use buttons and level sliders to adjust the values. The PM1122 will immediately react. This main screen will be called “mixer screen” on the next pages. To adjust minimum and maximum settings, click the “Edit” tab in the top bar and select “Settings”.
PM1122-INT DIGITAL INTERFACE REMOTE Recalling a preset can be done by selecting one in the dropdown list. To store or clear, push the corresponding open dialog button. When “Store dialog …” is pushed, a popup screen will appear: 17 WWW.APART-AUDIO.COM / INFO@APART-AUDIO.
PM1122-INT DIGITAL INTERFACE REMOTE The drop down list indicates how each possible preset can be recalled by using the contacts or the RF remote. If you have chosen a location, a name can be given. Please note these names are only intended for your convenience; they are stored in the control panel software but are not written to the PM1122‐INT. Next, you have to decide which settings have to be stored.
PM1122-INT DIGITAL INTERFACE REMOTE Controlling the PM1122INT with Hercules The RS‐232 port of the PM1122‐INT will commonly be used by a third party device to steer the PM1122. However, it can be used to change parameters and default settings or to store presets. For these purposes, communication between a computer and the PM1122‐INT becomes very handy.
PM1122-INT DIGITAL INTERFACE REMOTE Please read this carefully and click “close” after you have marked the “Don’t show later” check box. The program will open like this: Please click the tab “Serial” to continue. 20 WWW.APART-AUDIO.COM / INFO@APART-AUDIO.
PM1122-INT DIGITAL INTERFACE REMOTE In the frame named “Serial”, you have to provide communication settings. In the list box under “Name”, you have to choose the COM port. If your PC has a serial port, usually it is COM 1. If you use a USB to RS232 adaptor, it can be any number. If you’re not sure about the COM port, please refer to chapter “Help, where is my COM port?” at page 24. Next, the baudrate (Baud) needs to be configured. Default baudrate is 19200.
PM1122-INT DIGITAL INTERFACE REMOTE You can type immediately in the “Received/Sent data” text box. E.g. type “set valfb on”, followed by “Enter”. The PM1122‐INT will reply with “Command Executed!” and will send values of the control parameters whenever they are changed. In the “Send” frame, you can specify strings which will be transmitted if the “Send” button after the corresponding text box is pushed. E.g. type “get info” in a textbox.
PM1122-INT DIGITAL INTERFACE REMOTE This way, we could make it ourselves easy to create and store presets. In the first textbox we type:”set msclvl zone”. In the second one:”set miclvl zone” and finally in the third: “set select zone”. Now, if we want to change the music level of a zone, we only need to push the upper “Send” button and typing the zone number, a space and the desired value. The same way for the mic mix level and the source select.
PM1122-INT DIGITAL INTERFACE REMOTE Help, where is my COM port? To check the COM port name, look in Control Panel ‐> System ‐> Hardware ‐> Device Manager. You might need Administrator rights to access these pages. Ask your system administrator for assistance if necessary. Click Ports (COM & LPT) to view all available COM ports.
PM1122-INT DIGITAL INTERFACE REMOTE One possibility to handle this, is the following: A global string “rest_string” must be defined. At startup, it’s an empty string. Further, following procedures are used: • instr(1st_string, 2nd_string): this procedure returns the position at which the second string occurs in the first string or 0 in case there’s no match. • Left(string,integer) : this procedure returns the by the integer specified numbers of characters from the specified string, starting from the left.
