• A standard wipe causes the preview image to appear to unroll over the program image horizontally or vertically. A standard wipe can have either hard (sharp) or soft (fuzzy) edges.
Operation, cont’d • A square wipe causes the preview image to appear to unroll over the program image in one of two transitions (figure 3-35): • Starting at all four edges of the screen and moving in to the center of the screen. • Starting at the center of the screen and moving out to the edges of the screen. Figure 3-35 — Square wipe effects • A title effect produces two different effects: ECP window and ECP key.
ECP key causes any portion of the preview image which is over half intensity (.35V) to be displayed with the program image. As an example, by creating a preview image which is composed of white text on a black background, the white text will be the only portion of the image which will be keyed to the program image (figure 3-37).

SGS 408 Switcher 4 Chapter Four Serial Communication RS-232 Programmer’s Guide Control Software for Windows
Serial Communication, cont’d Serial Communication The switcher’s RS-232 connector can be connected to the serial output port of a host device such as an ECP 1000, a computer, or a control system. This connection makes software control of the switcher possible. Figure 4-1 shows a switcher RS-232 connection to a host serial port connector.
SGS error responses When the switcher receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the switcher is unable to perform the command because the command is invalid or contains invalid parameters, the switcher returns an error response to the host.
