Hello Glenn, we tested the signature pad in our office and used the code Alex provided above and it worked for us in 10.2 update 1. You might want to verify that the js files were updated after the patch.  At this point I guess it's best to open a support case if you cannot get it to work.  

Good Morning Everyone,  I have made the above mentioned edits to the script, with 10.2, update 1, and SigWeb installed, and still not working properly.  When the form loads and the signature button is clicked, the signature pane does display and switches to only the draw tab at the top, however, when you sign on the pad, nothing is displayed on the signature pane on the screen.  I am attaching the script I am currently using, which i believe is the same as Alexander's recommendation above with the exception of localhost being replaced with our LF server name.  I am also attaching the warning that is seen in the Chrome console when the signature window displays.

One last thought/question...  What does enabling SSL change to this process?  I am working with a test server to enable SSL and am seeing various warnings if i leave the path to the server as http://server or https://server.domain.coms,.  

var baseUri = "http://meadelf:47289/SigWeb/";

function initSigWeb(){
  var ctx = $("#sigTabContent .signatureSettings").get(0).getContext('2d');
  ResetParameters();
  SigWebSetDisplayTarget(ctx);
  tmr = setInterval(SigWebRefresh, 50);
  SetDisplayXSize(438);
  SetDisplayYSize(150);
  SetJustifyMode(0);
  SetTabletState(1);

  $("#sigNav a:eq(0)").hide();
  $("#form-signature-dlg").on("shown.bs.modal", function(){
    $("#sigNav a:eq(1)").click();
  });
  $("span.clearSignature").on("click", function(){
    SetLCDCaptureMode(1);
    KeyPadClearHotSpotList();
    ClearSigWindow(1);
    ClearTablet();
    $("button.signSignatureBtn").removeAttr("disabled");
    setTimeout(function(){SetLCDCaptureMode(2);}, 2000);
  });
  $("#form-signature-dlg").on("hidden.bs.modal", function(){
    SetLCDCaptureMode(1);
    KeyPadClearHotSpotList();
    ClearSigWindow(1);
    ClearTablet();
  });
}

$(document).ready(function(){
  if (!window.isPrintMode){
    $.getScript("http://meadelf:47289/SigWeb/SigGetScript/SigWeb.js", function(){
      initSigWeb();
    });
  }
});

First, make sure to apply Forms 10.2 Update 1.

Next, try using this updated javascript code on the form:

var baseUri = "http://localhost:47289/SigWeb/";

function initSigWeb(){
  var ctx = $("#sigTabContent .signatureSettings").get(0).getContext('2d');
  ResetParameters();
  SigWebSetDisplayTarget(ctx);
  tmr = setInterval(SigWebRefresh, 50);
  SetDisplayXSize(438);
  SetDisplayYSize(150);
  SetJustifyMode(0);
  SetTabletState(1);

  $("#sigNav a:eq(0)").hide();
  $("#form-signature-dlg").on("shown.bs.modal", function(){
    $("#sigNav a:eq(1)").click();
  });
  $("span.clearSignature").on("click", function(){
    SetLCDCaptureMode(1);
    KeyPadClearHotSpotList();
    ClearSigWindow(1);
    ClearTablet();
    $("button.signSignatureBtn").removeAttr("disabled");
    setTimeout(function(){SetLCDCaptureMode(2);}, 2000);
  });
  $("#form-signature-dlg").on("hidden.bs.modal", function(){
    SetLCDCaptureMode(1);
    KeyPadClearHotSpotList();
    ClearSigWindow(1);
    ClearTablet();
  });
}

$(document).ready(function(){
  if (!window.isPrintMode){
    $.getScript("http://localhost:47289/SigWeb/SigGetScript/SigWeb.js", function(){
      initSigWeb();
    });
  }
});

This is a known issue and has been fixed in the coming hotfix.

I have had the T-S460-HSB-R working sucessfully with a client running Forms up to version 10.1. The 10.2 update broke the ability to capture signatures. I have reinstalled the sigweb drivers and service, but cannot get the signature pad working with forms again.
