CB512 HD Caption Legalizer / Relocating BridgeThe S function mapped to GPI-A takes precedence over the D function mappedto GPI-B. If the S function is mapped to GPI-A, then GPI-B has no effect onthe caption source.The h command, described on page 8, takes precedence over boththe S and D GPI settings. This means that if the h mode has beenenabled, only the Source Video is used for caption data regardless of GPIsettings.Entering the R command with no parameters will display thecurrent GPI configuration.Entering the R command with four hyphens will return the GPIconfiguration to the factory default.The following table identifies the valid settings for each of the GPI switches.Valid setting options are:Switch A Switch B Switch C Switch D- RT/LT/RB/LB/T/BSD- Hypen = default functionalityT/B(n) Top or Bottom, followed by the row numberS Caption source input select modeD Disable bridging from Source Video (when GPI asserted)Examples:R - B4 T4 - assigns the GPI-B switch to protect thebottom 4 rows of the screen from caption overlay and GPI-C to protect the top4 rows, and leaves the GPI-A and GPI-D switches to perform their defaultoperations.R s B4 LT4 RT4 maps GPI-A to source input selectmode, assigns the GPI-B switch to protect the bottom 4 rows of the screenfrom caption overlay, GPI-C to protect the top 4 rows while mapping all HDcaptions to the left, and GPI-D to protect the top 4 rows while mapping all HDcaptions to the right.To place the above command in NVM so that the encoder will automaticallypower up in the mode described in the example above, you would enter:w R s B4 LT4 RT4 14©2009-2011 EEG Enterprises, Inc.
