browser.driver.findElement(by.id(browser.params.loginPage.IdTextBoxCode)).then(function(codeTextBox)
    {
        try 
        {
            console.log("Entering Code: "+code);
            codeTextBox.sendKeys(code);
        }
        catch(err) {
            console.log('In catch block');
        }
   }, function(err) {
        console.info('Code Text Box not displayed on page. Proceeding with default Code');
    });
