Most keyboards and mice will also operate at distances of 20 metres. A2. SmartView to PCs 1 to 16 Cable specifications: Video - 15 pin high density male D connector to 15 pin high density male D connector wired as a standard VGA PC to monitor cable. There are two types commonly available. The best type cables which will give excellent quality are constructed with coaxial cable cores. Cheaper ‘data’ cables are often used, but can degrade video quality if used over longer distances. Avoid using 'data' cables longer than 2 metres unless the video quality is not important. Good quality coaxial video cables may be run at distances up to 50 metres with little loss of video quality. Keyboard and PS/2 mice - 6 pin mini-DIN male connector to 6 pin mini-DIN male connector with all lines connected straight through (1-1,2-2 etc.). If the PC has a 5pin DIN AT style keyboard connector you will need a PS/2 to AT keyboard adapter 6-pin mini-DIN female to 5-pin DIN male (readily available). Cables should be no longer than 30 metres. SmartView Installation and Use Page 37 SmartView Installation and Use Page 38 RS232 serial mice - these require a special converter to connect the RS232 lines present on the SmartView mouse ports to the RS232 port on a PC. Cables should be no longer than 30 metres. A3. Expansion port pin assignments The 15 way D connector located on the back of the SmartView provides connections for the remote control module and allows an external RS232 device to control the SmartView. See section 3.5 for more details. Pin 9 = GND Pin 11 = RXD Other pins to be left unconnected Appendix B. Problem Solving Problem: Poor video quality with smearing fuzziness or ripple. Action: Use screened coaxial video cables to connect your devices to the SmartView. Problem: Mouse does not move cursor on screen. Action: Ensure that the mouse and computer are both connected to SmartView before power is connected and ensure that the SmartView is powered on before the attached computer. Ensure that your software is configured to accept a Microsoft compatible mouse of the type that you have connected (PS/2 or RS232). If you move the mouse and the activity indicator (dot on 7 segment display) does not flash then the SmartView is not receiving data from the mouse. Check the mouse connection to the SmartView, try resetting the mouse using the reset function (section 3.3) or re-powering the SmartView. If you are attempting to connect the SmartView to a CPU with a PS/2 mouse connection that has not been powered down then you will need to use the mouse restoration functions F5 or F6 (see section 2.9). Problem: Keyboard does not function or functions intermittently. Num lock light does not always come on when the num lock key is pressed. Action: Some older keyboards were designed for use with specific computers and are not truly AT or PS/2 compatible. These are not common but if you experience problems try another keyboard. SmartView Installation and Use Page 39 Problem: Mouse causes channel to change. Action: Some cheaper mice are not fully compatible with the SmartView and can lose data causing the channel to be changed (if mouse switching of channels is enabled). If you experience this problem then change the mouse and use a Microsoft, Logitech, IBM, Compaq or Hewlett-Packard type. Ensure that you are using a Microsoft compatible mouse driver on your PC. Some other manufacturers’ drivers may switch the mouse to use a proprietary mouse data format not supported by the SmartView. If you have unplugged and re-connected a mouse to the SmartView then ensure that you reset it using the mouse reset function (see section 3.3). Problem: Mouse jumps around the screen after disconnecting the mouse cable or powering down the SmartView. Action: If you have disconnected and re-connected a CPU mouse cable or you have powered down the SmartView then the mouse data format may be out of synchronisation with that required by the PC (PS/2 or Intellimouse). Try the ‘restore Intellimouse’ function (F6) to resolve the problem or re-power the CPU. Problem: SmartView does not power on correctly (display is blank or stuck after power on). Action: Switch the SmartView off and leave for 10 seconds. Re-power the SmartView, preferably from a switch on a wall socket rather then by plugging in the connector to the rear panel of the SmartView. Try switching off all the connected CPUs and switching on the SmartView first. If this action does not resolve the problem then there is a fault with the SmartView. SmartView Installation and Use Page 40 Problem: Video appears to be lost after a PC has gone into auto power down mode. Moving the mouse and typing at the keyboard does not wake it up. Action: Some computers tested output an incomplete video signal in auto power down mode. The on-screen menu cannot ‘lock on’ to this signal and so cannot be displayed under these conditions. If the Adder menu is left on the screen and this type of auto power down occurs then the screen b...
