Introduction The Remote Display is a richly-featured measurement system that allows for the simultaneous connection of up to four gauges and displays their current measurements on a connected Android tablet. In addition, the Remote Display can connect to up to two external data consumers (desktop computer, laptop, PLC, or any generic serial device) over RS-232 and USB. The Remote Display has been designed to work with nearly any gauge that outputs data in Digimatic format.
Hardware Overview The front panel of the Remote Display Mux Box contains the connectors for up to four gauge channels. Each 10-pin connector supports both quadrature probes and any gauge that supports Digimatic communications. 1 Global send footswitch for triggering updates on all connected channels. 2 Four 10-pin gauge channel connectors The rear panel of the Remote Display Mux Box the power and communication interface connectors, as well as a power indicator LED.
Quickstart Guide The following instructions will demonstrate how to operate the Remote Display with one Digimatic indicator and one quadrature Probe. 1. Plug in the supplied power adapter to the Remote Display Mux Box (item 5 on page 3). The red LED on the rear panel will light up. 2. Power up the supplied Android tablet. Press and hold the On Button (approx. 5 seconds) until HP logo appears on screen and then release the On button. The display will take approx. 30 seconds to startup.
Android Application Operation Launching and Connecting The Remote Display Android application will automatically launch and connect when the tablet is connected to the Remote Display Mux Box. Alternatively, the app can be launched by clicking on the Remote Display icon from the App Drawer. After connecting the Android tablet to the Remote Display Mux Box and launching the app, the system will establish communication.
Main Display The main screen of the Remote Display application is shown below. As channels are enabled and disabled, the screen will update dynamically to maximize the amount of screen area available. This example shows two con e ted de i es ha els is a Quad atu e QUAD i st u e t a d ha el is a Digi ati DIGI i st u e t. If Digi ati is hose as Gage T pe a d o device is connected to that channel, then TIMEOUT will appear on the display.
Regardless of the type of connected device (Quadrature or Digimatic) there are several settings that are always available. These settings are summarized in the following list: Setting Channel Enabled Gage Type Unit Type Mode Absolute Offset Travel Direction Tolerance High Tolerance Low Tolerance Ratio Mode Ratio Value Automatic Log Log Interval (s) Show Analog Scale Analog Scale Show Leading Zero Notes Enables/Disables channel. Disabling a channel will hide it from the main display.
Digimatic Devices Channels can also be set up to read output from Digimatic devices. These devices need to be polled for their current data. The following settings are only available for Digimatic channels: Setting Log on Request Auto Request Request Interval (s) Notes If enabled, a timestamped entry will be made to the data log every time the data is refreshed manually Enables/Disables automatic data refresh. Sets the data update interval if Auto Request is enabled.
To install PuTTY, follow this procedure: 1. Once on the Putty we site s oll do to “ite ap a d li k o Download PuTTY! 2. Scroll down to Windows Installer for everything except PuTTYtel click on Installer: putty-0.63installer.exe. 3. When the installer finished downloading, double-click on it to start. Follow the prompts to complete the installation. To open the VCP and query the Remote Display for the current gauge reading on channel one, follow these steps.
3. Click on Connection -> Serial on the left sidebar, and make sure the connection parameters are set as shown below (Enter COM Port number if different from COM1) 4.

If nothing is displayed on the terminal screen, disconnect the device, cycle power, and then repeat this procedure. 6.
RS-232 Serial Connection The Remote Display supports an RS-232 connection to data consumers, such as a computer or PLC. To connect the Remote Display to an external RS-232 device, use the following procedure: 1. Find the female RS-232 connector on the rear panel of the Remote Display Mux Box. 2. Using a shielded RS-232 cable, connect the Mux Box to the external data consumer. a. Depending on the device and cable configuration, it may be necessary to use a femaleto-male gender changer.
Parameter List The following list summarizes the configuration parameters available for configuring each device channel. When editing these values over RS-232 and/or USB, make sure to call the Save command to commit the values. Otherwise, they will be reset if the Remote Display is powered down. Important Note: While these parameters can be changed over RS-232 and USB, the preferred way to edit these settings is by using the Channel Settings menu on the Android application.

Supplemental Information Digimatic Interface The following describes the standard 10-pin Digimatic connector pinout. Signal Timing Figure 1-1 shows a timing chart for the case where the host device triggers a data transfer by asserting the active-low request signal (/REQ). The gauge then sends data (the DATA signal) that is clocked by the CK line. In this case, the data ready (RDY) line is not applicable.

Digimatic Data Format 20
Quadrature Signal Format The following diagram and schematic describe the format of quadrature data that the Remote Display is expecting to receive. Failure to meet these specifications will not guarantee proper functionality of quadrature devices. Expected Quadrature Signal Quadrature Conditioning Circuit The following circuit is used internally in the Remote Display to condition the quadrature signals for decoding.
