11. Sections 3 2 1 and 3 3 4 In this application the Remote Module also functions as a sync stripper It strips the sync signals from the color signals separates them and presents them as normal TTL signals to the VGA monitor IMPORTANT NOTES You can only connect a VGA monitor to an RGB video source if the monitor is able to process the source s synchronization frequency for example a multisync monitor with horizontal bandwidth of 30 to 90 kHz probably won t work with a WF470 graphics adapter that uses a frequency of 15 625 kHz The Extender can not generate the special VGA standard phase relation required by some types of dual scan monitors LCD panels etc Be aware that because of the way some RGB cards output sync signals it is possible that despite how the jumpers are set in your Local Module your monitor will still receive CSYNC on its HSYNC lead as well as VSYNC on its VSYNC lead Some VGA monitors have no problem with this but others will suffer from distorted displays If your monitor is affected by this distortion you can suppress the VSYNC signal by removing the Remote Module s JP9 jumper the monitor should work fine using CSYNC only See Section 3 3 3 Siemens users The Extender can process CP581 signals but this requires special cabling Call Black Box for technical support CHAPTER 3 Configuring the ACS235A Table 3 1 Jumper Settings For all of these applications to use AGC you must leave JP3 in the Loca

13. The RGB red green and blue color signals are analog values in the range of 0 to 0 8 Vpp The composite horizontal vertical synchronization signal is usually added to the green signal although some devices also add synchronization or other information to the red and or blue signals Normally the color signals have a DC offset or at least the green SYNC signal does this means that DC voltage is added to the lead so that even when there s no color signal present when the screen is black the color lead with the DC offset has higher voltage than the ground lead These signals must be clamped at the remote end for linear amplification in stages that follow CHAPTER 5 Installation 5 1 4 KEYBOARD AND MOUSE The ACS235A Extender s keyboard and mouse interfaces are standard PS 2 type interfaces so you can attach just about any standard PS 2 compatible keyboard and mouse to the Extender Do not attach serial mice or bus mice to the Extender they will not work You can attach a PC AT style keyboard with a 5 pin DIN connector to the Extender by using a keyboard adapter available separately as product code FA211 The ACS236A Extender s keyboard and mouse interface is a standard Sun type interface so you can attach just about any standard Sun compatible keyboard and mouse to the Extender The Extender is transparent to Sun keyboard type and keyboard language 5 1 5 PARALLEL PRINTER OPTIONAL WITH ACS235A The ACS235A Extender s
