Each manufacturer may have its own terms, so look for terms like “auto setup”, “auto sync”, “pixel phase”, and “tracking”. Operating Problems The table below shows some common operating problems and their solutions. Problem Cause Solution No image appears. The input signal is Attach an input device that is incompatible. compatible with NTSC 3.58, NTSC 4.43, PAL, or SECAM. Freeze mode was Deactivate freeze mode entered when the image was black.

The control device (host) can use either Extron’s Simple Instruction Set (SIS) commands or the graphical control program for Windows. The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control. The rear panel RS-232 9-pin D connector has the following pin assignments: Pin RS-232 function Description 1 – No connection2 Tx Transmit data 3 Rx Receive data 4 – No connection5 Gnd Signal ground 6 – No connection7 – No connection8 – No connection9hardwired IR IR input 51 96 DB9 Pin Locations Female RS-232 Programmer’s Guide Host-to-scaler communications SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the DVS 406 determines that a command is valid, it executes the command and sends a response to the host device. All responses from the scaler to the host end with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters. It is also possible to send several SIS commands back-to-back in sequence. Scaler-initiated messages When a local event such as a front panel selection or adjustment takes place...
