manual abstract
To set the desired Sync Delay time press and hold the appropriate button on the front panel while turning the unit on/plugging the unit in. The delay time will be stored until the setting has been changed. SYNC DELAY SET 0.0 second delay Press & hold Input 1, Power ON 0.5 second delay Press & hold Input 2, Power ON 1.5 second delay Press & hold Input 3, Power ON 2.0 second delay Press & hold Input 4, Power ON The factory default setting for the MX2206RM is 0 delay. To reset the unit to this default, input 1 must be pressed and held during the power up sequence. The sync delay setting will not be lost by reset or by powering OFF the switcher. 4.4 AUTO SWITCH MODE BUTTON This function allows the MX2206RM to automatically select an active signal by sensing incoming sync. To enable Auto-Switch mode, press and hold this button (F1) for approximately 2 seconds. When in Auto-Switch mode, the rear panel LED lights will “scan” for an active signal until one is found. Auto switching is only available when switching RGBS format signals. 4.5 STAND BY / ALL CHANNELS OFF BUTTON This function allows a user to turn OFF all input signals. It is very useful when the MX2206RM Switcher is used in applications where there is a need to turn the display or the source OFF. Press this function key (F2) to switch to no a signal condition. The LED next to the F2 will light to indicate that the unit is in this mode. To resume input Select switching, simply press the desired INPUT. 4.6 RESET BUTTON This function allows a user to RESET the switcher without unplugging the unit. Press the function key RESET (F3) and hold it for 2 seconds. When you hear beeping, release the key. All of the LED’s will flash simultaneously. The switcher is reset. All previous defaults, such as power on channel default and other user settings are maintained. 4.7 BEEP ON/OFF BUTTON This function allows a user to have audible feedback when buttons are pressed. The factory default is beep ON; however, in some applications, sound may be undesirable. To disable sound, press this function key (F4) and hold it for approximately 2 seconds until a beeping sound is heard. The function is disabled. To enable it, repeat the same steps. The setting is stored in the memory and is maintained during the power up sequence. 4.8 POWER UP DEFAULT SET This function allows a user to select the channel that will be ON at power up. To select the default channel, press the selected channel switch and hold it for approximately 2 seconds until you hear a beeping sound. If the unit is turned off and turned back on, the LED of the selected channel should light. 4.9 ANALOG OUTPUT The analog output of the MX2206RM can be used for controlling several switchers simultaneously. The analog amplifier drives analog output pin 9 on 5 SWITCHERS a 9-pin “D” connector. The output can switch from 0V to approximately 5.0V. The output impedance of this pin is 100 Ohms and it can sink or source up to 5 mA of current. By using this output, several switchers can operate in gang mode. To do this, the analog output of the master switcher (pin 9) is connected to the analog input of the slave switchers (pin 9). Now, every time a channel is selected on the master switcher, the output voltage of the analog output will be set to switch all other switchers into the same channel. The simplicity of this approach is that only 2 wires (one to pin 9 and one to ground) are required to connect and control all of the switchers. The selection of channels can also be accomplished by RS-232 on the master switcher with all slave switchers connected through the analog control pin. A maximum of four switchers can be connected in this configuration. 4.10 POWER SUPPLY The MX2206RM Switcher has 5V power supply available on pin 8 of the 9-pin “D” connector. This voltage can be used to drive external circuits or as a pull up voltage for open collector type outputs. The total current on this pin should not exceed 150 mA continuous operation or 500 mA for 5 minutes. APPLICATION DIAGRAM 5 6 SWITCHERS INSTALLING YOUR SWITCHER 6 Step 1. Make sure that the power input is set to the proper AC voltage in your country. An incorrect setting can result in unit damage not covered by warranty. Step 2. Connect the power cord to the unit and plug it into the power outlet. Step 3. Connect the cables from the video sources (computers) to the input channels and connect the output channel to the display device (i.e. monitor or projector) Step 4. If control system is used to control the unit, connect RS-232 port to the control system RS-232 card. An improper hook up may result in RS-232 interface damage. Step 5. Verify that picture quality on the display is good. If you are not receiving a signal, make sure that the display is compatible with the resolution of the computer graphics card. Contact Closure control requires the use of part #RC5204CC Cable. CONGRATULATIONS! YOU ARE DONE. If you experience any problems, please call 1-800-258-4623 or 1-714-9...
