Page 3: Overview
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. Further, the RS‐232 port will have to be used to store presets, adjust minimum and maximum level settings. Strings can be sent via third‐party software like Hilgraeve’s Hyperterminal or the freeware utility “Hercules SETUP utility” from HW‐group. For preset control using contacts, it’s needed to store the presets using RS‐232. It can be done using terminal software (Hyperterminal, Hercules, ...) or with the APart PM1122 Control Panel software. Please note the APart software runs only on Windows® platforms, it’s freely downloadable but no support or guaranties are given. Once the presets are stored, no RS‐232 communication is needed anymore. Refer to the chapter Presets for more information. For control using the optional RF module, no configuration with RS‐232 is needed. Once the module Easywave is mounted (see chapter “ ” on page 9), the push buttons at the front side are enough to assign a switch to a zone. Please note there are some features which can be configured using RS‐232 but for normal operation, it’s not needed!

Page 5: Instruction Set Pm1122-Int
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 PM1122‐INT front panel description a LED bar. Please refer to “ ” 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. Standard ASCII strings are used to control the PM1122‐INT so it’s possible to use Terminal software (e.g. HyperTerminal, Hercules, ...) to test, configure and/or control it. Instructions are not case sensitive. Each string must be ended with a Carriage Return (<CR>, ASCII code 13 or ”\n”) The string is structured in the following order: Command Attribute Parameter1 Value<CR> Strings require a space between each parameter; the last character in the string needs to be a carriage return <CR>. Line feed <LF> characters are ignored so they may be used. An instruction consists of a command, an attribute and possible one ore more parameters. E.g. the instruction to switch the music volume from zone 1 at maximum will look like this: SET MSCLVL ZONE1 100<CR> where SET is the instruction, MSCLVL the attribute, ZONE1 the first parameter and 100 the second parameter which is the value.

Page 9: Easywave
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. Next to that are an up and down button controlling the music level and finally the same 2 buttons controlling the microphone level. Assigning an RF switch is as simple as pushing the “Learn” button from the corresponding zone (x) and then push any buttons of the RF switch within 5 seconds. In case the PM1122‐INT is in a less accessible place, this can also be done by an RS232 instruction. “LRN RFKEY ZONEx<CR>” has the same effect as pushing the “Learn” button from zone x. Clearing of the memory or un‐assigning the RF switches also can be done in 2 ways: pushing the “Clear” button on the PM1122‐INT for at least 2 seconds or by the instruction “CLR RFKEY ALL<CR>”. Two extra features can be configured by RS‐232: • “Mute”‐buttons: the music level or mic mix level will be put at minimum if the level down button is double clicked. To enable this feature, the following RS‐232 command should be executed: “SET DBLCLICK ON<CR>”. Corresponding, the feature can be disabled by the WWW.APART-AUDIO.COM / INFO@APART-AUDIO.COM... - Page 10 PM1122-INT DIGITAL INTERFACE REMOTE command: “SET DBLCLICK OFF<CR>”. 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<CR>”. Please note this will take effect on all switches assigned to the Presets same zone. For more information about presets, please refer to chapter “ ” at page 11. To put the default configuration back: to select sources, next instruction needs to be executed: “SET RFKEY ZONEx SELECT<CR>”. WWW.APART-AUDIO.COM / INFO@APART-AUDIO.COM...

Page 11: Presets
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. 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 in the chapter Easywave “ ” at page 9. The table below describes the preset memory and the recall behaviour. Zone 1 Zone 2 Recall by Preset Selector Music Level Mic Mix Level Selector Music Level Mic Mix Level Contacts Easywave A - 1... - Page 12 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. To do this, type the following instructions in the terminal window: SET SELECT ZONE1 B<CR> SET MSCLVL ZONE1 100<CR> SET MICLVL ZONE1 0<CR> SET SELECT ZONE2 D<CR> SET MSCLVL ZONE2 50<CR> SET MICLVL ZONE2 50<CR> Now all controls are at the desired level. To store them in preset 2, use the following instruction: STR PRESET 2<CR> Example two: by recalling preset 7, we want only zone2 to change. The wanted controls are: selector at source C, music level at 20% and mic mix level at 70%. Again, first we will have to set the controls at the desired levels: SET SELECT ZONE2 C<CR> SET MSCLVL ZONE2 20<CR> SET MICLVL ZONE2 70<CR> Now we want to store only the values from zone 2 to preset 7: STR PRESET ZONE2 7<CR> A preset can be overwritten by storing at the same preset number or cleared by the CLR command. To clear preset 5, use the following instruction: CLR PRESET 5<CR> To clear the complete preset memory: CLR PRESET ALL<CR> Recall a preset Recall a preset by contacts Two times 6 presets can be recalled this way. The EUROBLOCK connector has 8 pins, COM A, COM B and 1 to 6. Making contact between COM A and contact 1 to 6 will recall the corresponding preset 1 to 6. Making contact between COM B and contact 1 to 6, will recall preset 7 to 12. The contact can ...

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. Again a few examples: To recall the settings as stored in preset 2 (if the preset was stored for both zones, then the stored settings will be applied to BOTH zones): RCL PRESET 2<CR> To put the levels of zone 2 to the minimum and source of zone 2 to “A”: RCL PRESET ZONE2 0<CR> To recall preset number 1 settings to zone 1 only (even if the preset has been stored as a zone 1 and 2 preset): RCL PRESET ZONE1 1<CR> PM1122 Control Panel Software In order to test and demonstrate most of the PM1122‐INT features, a custom application called PM1122 Control Panel was developed. This software tool runs only on windows® platforms. It’s offered for didactical use. It can be very handy to create and store presets. Please note the software is offered for free but there is no guarantee it will work on every platform and no support is given. If the program is not working on your platform, please use terminal software. Please refer to chapter Controlling the PM1122‐INT with Hercules “ ” at page 19 to learn more about our recommended and included alternative. You will need a computer running Windows 2000/XP/vista with a 9 pin RS‐232 COM connector and a standard straight through serial cable. If no serial port is available on your computer, you can use a USB to serial converter. It’s recommended to install the USB to serial converter drivers before installing the PM1122 Control Panel software. The setup for the “PM1122 Control Panel” software can be found on the included CD but if you have internet access, please check the website for the latest version.

Page 19: Controlling The Pm1122-Int With Hercules
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. If you use a PC which has Windows 2000 or XP as operating system, there is program called Hyperterminal available which is perfectly suitable for this purpose. On Vista however, this program is no longer available. Because of that, we decided to distribute “Hercules SETUP utility”. This is a freeware program from HW‐group. It can be found at http://www.hw‐group.com/products/hercules/index_en.html or on the included CD. It doesn’t have to be installed so you can run it directly from the CD. It also works on Windows XP and has some nice features so it is our favorite! Open the application by double clicking “Hercules.exe”. Like stated before, the program can be launched directly from the CD. The security software on your computer might block the program. In that case, click “unblock” to continue. The first time the program starts, the following screen appears: WWW.APART-AUDIO.COM / INFO@APART-AUDIO.COM... - Page 20 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. WWW.APART-AUDIO.COM / INFO@APART-AUDIO.COM...
- Page 21 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. If you’re not sure it is PM1122‐INT front panel description still at default setting, please refer to chapter “ ” at page 3 on how to check the current baudrate setting. Other settings are “Data size”: 8, “Parity”: none, “Handshake”: OFF and “Mode”: Free. Now click “Open”. WWW.APART-AUDIO.COM / INFO@APART-AUDIO.COM...
- Page 22 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<CR>” in a textbox. When “Send” is pushed, the “get info” sting is transmitted and the PM1122‐INT will reply with a list of the control parameters and their value if “VALFB” is on. WWW.APART-AUDIO.COM / INFO@APART-AUDIO.COM...
- Page 23 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. After all control settings settings are at the desired level, just type “str preset ” followed by a zone if needed and the preset number.

Page 24: Help, Where Is My Com Port
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. Here we find it’s COM4 How to deal with bidirectional communication Keeping your system in sync with the PM1122 might look difficult but actually it isn’t if you follow the right strategy. If you are writing a VB project or configuring a system like Crestron, you might experience the same difficulty. What’s it all about? When a preset is recalled or when a “GET INFO” command is executed, a big number of characters are transmitted by the PM1122‐INT. Possible receiving only a part of this string, will call your routine which handles the received data. Although this string is not complete, it might already contain more than one value. For example, a “GET INFO” command might call your receive handler 3 times. In the next example, for clarity, a <CR> is represented by “\r” and <LF> by “\n”. The first time the received string might be:” MSCLVL ZONE1 19\r\nMICLVL ZONE1 0\r\nSELECT ZONE1 A\r\nRSRFFU ZONE1 0\r\nMAXMSC ZONE1 99\r\nMAXMIC ZONE1 60\r\nMINMSC ZO”. The second time it is: “NE1 10\r\nMINMIC ZONE1 0\r\nMSCLVL ZONE2 0\r\nMICLVL ZONE2 0\r\nSELECT ZONE2 C\r\nRSRFFU ZONE2 0\r\nMAXMSC ZONE2 80\r” and finally the last time it’s: “\nMAXMIC ZONE2 100\r\nMINMSC ZONE2 0\r\nMINMIC ZONE2 0\r\nREMOTE ZONE1 1\r\nREMOTE ZONE2 1\r\n” WWW.APART-AUDIO.COM / INFO@APART-AUDIO.COM... - Page 25 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(1 _string, 2 _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. • Right(string, integer) : this procedure does the same but starting from the right side. • Interpret(string): this procedure interprets a string which includes a name, a zone and a value as send by the PM1122‐INT. Receive_Handler(string received_string): { rest_string = rest_string & received_string while(instr(rest_string,”\r\n”) <>0) { Dim first_string as string first_string = left(rest_string, instr(rest_string,”\r\n”) – 1) rest_string = right(rest_string, len(rest_string – instr(rest_string,”\r\n”) – 1) ...
