AdderView GEM Installation and Use Page 22 Examples of common hotkey sequences (assuming CTRL + ALT hotkey option): To select channel 2: press ba2 ba2ba2 release 2ba 2ba2ba To 'tab through' channels: press ba babav vvrelease v vvpress v vv v vv v vvvba vbavba release press release 3.5 Mouse control Computers may conveniently be selected using a three button mouse. In order to switch to the next computer simply hold down the central mouse button (the wheel mouse button on an IntelliMouse) and click on the left hand mouse button to select the next computer or the right hand mouse button to select the previous computer. If the AdderView has been set to scan active ports then the next or previous active channel will be selected. If it has been set to scan all ports then the next or previous numerical channel in sequence will be selected (see section 4.5 for more details). Mouse switching may be enabled or disabled by setting options during configuration (see section 4.3). When mouse switching is disabled the third button or wheel button state is ‘passed through’ the AdderView and seen by the application software.

To select a channel the data rate of the sending device must be set to 1200 baud, 8 bits, no parity and 1 stop bit. No handshaking is used by the AdderView GEM. Simply send the character for the channel which needs to be selected, for example ASCII ‘1’ (hex code 31) will select channel 1, ASCII ‘2’ (hex code 32) will select channel 2 and so on. The AdderView will echo the ASCII character back to the sending device when the channel has been changed. The serial interface pins are found on the options connector on the rear of the AdderView. Pin assignments for this connector are given in appendix A. 3.7 Cascading AdderView GEMs AdderView GEM switches can be connected together to expand the number of connected computers. When cascading AdderView GEMs a power adapter (AVGPSU) must be connected to each AdderView GEM. AdderView GEMs can be connected in a cascaded tree structure. This can be particularly useful where clusters of computers are located some distance from each other because each unit acts as data booster and can each be up to 30 metres away from the next AdderView GEM. The channel can be selected on remote AdderView GEM units using an extension of the HOTKEY control . For example, consider a situation where two AdderView GEM units are connected together as shown below. To connect to the computer attached to port 3 on AdderView GEM B the user would hold down the hotkey keys then press ‘2’ followed by ‘3’, whilst keeping the hotkey keys pressed. This will have the effect of connecting to port ‘3’ of the AdderView GEM which is connected into port ‘2’ of the first AdderView GEM unit A. For example to connect to port 3 on the AdderView GEM cascaded off port 2 of your first AdderView GEM use: press ba baba2 22release 2 22 press 3 33release 3 33ba baba AdderView GEM Installation and Use Page 24 AdderView GEM Installation and Use Page 25 A typical cascade of two AdderView GEMs 3.8 Synchronising AdderView GEMs for multiple video head applications Multiple AdderViews may be connected together so that they operate in a synchronised manner. Synchronised operation is useful for applications that require multiple video signals to be switched together. This type of operation is usually required where each computer is fitted with multiple video cards or video cards with multiple video heads. Such configurations are typically required in banking and engineering applications where greater video 'real estate' is required. Whenever the AdderView's channel is switched it sends an RS232 command out on its serial interface. The AdderView switches its channel if it receives the same command on AdderView GEM Installation and Use Page 26 its serial interface. Consequently, by linking the serial interfaces a master unit may be made to automatically switch a daisy chain of slaved units as shown in the diagram below. The slave units will require the optional power adapters because they cannot draw their power from the video link alone. Synchronised AdderView GEMs used for a dual head video switching application 4. AdderView GEM configuration options All the options described in this section are entered in AdderView GEM configure mode - see section 2.6 for instructions on entering configure mode. 4.1 Screen saver time delay AdderView GEM contains a programmable screen saver which will blank the display after the set time delay with no keyboard or mouse activity. Simply typing at the keyboard or moving the mouse will re-enable the display. The display will flash whilst the AdderView GEM is in screen save mode. B1 - screen save...
