This is the core data and video channel between VDP and control cabinet PC, consisting of two RJ45 interfaces:
XSER (Data Interface): Color coded in purple, transmitting control data, keyboard signals, etc.
XVID (Video Interface): Color coded in black, transmitting display signals.
Connecting cables: Pre made cables specified by Bosch Rexroth (part numbers starting with R91117) must be used, with lengths ranging from 0.5 meters to 50 meters. Using non specified cables may cause signal interference or functional failure.
Relationship between cable length and resolution:
800 x 600 pixels: up to 80 meters in length.
1024 x 768 pixels: up to 70 meters in length.
1280 x 1024 pixels (VDP 60.3 only): up to 60 meters in length.
Expansion plan: When a longer distance is required, a Y-shaped repeater (VAC 01.1, part number R911171187) can be used for relay, which can cascade up to four operation display terminals.
DIP switch (S1):
S1/2 switch: used to adapt to long-distance cables. When the CDI cable length connected to the control cabinet PC is ≤ 30 meters, set it to OFF; When the length is greater than 30 meters, set it to ON. This setting affects the working speed of the USB interface.
Functional Area (FE) Connection:
Critical: It is necessary to ensure the reliable connection of the functional ground (M5 screw terminal) between the VDP terminal and the control cabinet PC. Otherwise, when only one side of the device's power supply is interrupted and restored, electronic devices may be damaged due to potential differences. The optimal approach is to connect the two functionally directly.

Mechanical installation and environmental requirements
Installation steps:
Process and install holes (with a diameter of 5mm) on the installation panel according to the drawing.
Remove the protective paper from the back sealing strip of the front panel.
Insert the terminal into the opening from the front, allowing the mounting bolt to pass through the hole.
Tighten the M4 nut with a torque of 1.4 Nm from the back of the panel to avoid mechanical damage.
Installation environment:
Space: At least 50mm of space should be reserved around the equipment for heat dissipation and cable layout.
Direction: Only vertical installation is allowed, with a maximum deviation of ± 45 degrees from the vertical direction.
Wiring: Cables should reserve loops and use stress relief devices. CDI cables must be kept away from strong interference sources such as motor cables, as parallel wiring can cause signal interference.
Environmental conditions:
Operating temperature:+5 ° C to+45 ° C.
Storage/transportation temperature: -20 ° C to+60 ° C.
Humidity: During operation and storage, the relative humidity should be between 5% and 85%, and condensation is not allowed.
Vibration and Shock: Compliant with EN 60068-2-6 (Vibration) and EN 60068-2-27 (Shock) standards, suitable for industrial environments.
Operating elements and device description
Membrane keyboard:
The device comes pre installed with an English keyboard driver, which supports language independent operations and does not require changing the driver for different language interfaces.
Function keys (F2-F9) and operation keys (OP2-OP9): Their functions are defined by the upper layer application software.
Machine function keys (M keys): L1-L8 and R1-R8 keys located on the left and right sides of the screen. Its status can be read in two ways: as a USB keyboard signal transmitted to the PC; or as a bit encoded form transmitted to the control cabinet PC through a serial connection of CDI interface, and can be further output through Profibus DP card insertion.
Status and error display LED:
The front panel provides system status indicator lights, such as:
HDD (yellow): Flashing indicates hard disk access; Continuous flashing may indicate SMART error.
Temp (red): Constant light indicates equipment temperature>50 ° C; flashing indicates control cabinet fan failure.
UPS (red): It lights up to indicate that the control cabinet PC is using UPS power supply and the main power supply has failed.
Note: Not all LEDs are activated on all control cabinet PCs, please refer to the PC documentation for details.
Safety, Maintenance, and Compliance
Security Warning:
The document adopts the security identifier of ANSI Z535.6 standard:
Danger: Failure to comply may result in death or serious injury.
Warning: Failure to comply may result in death or serious injury.
Caution: Failure to comply may result in minor injuries.
Tip: Failure to comply may result in property damage.
Touch screen operation: Only finger or dedicated stylus (part number 1070923266) operation is allowed, using sharp objects may damage the screen.
maintain:
Backlight: As a vulnerable component, the lifespan of the backlight is approximately 50000 hours (at an ambient temperature of 25 ° C). After the end of its lifespan, the brightness drops to 50% of its initial value. You can set the backlight off delay through the Windows' Power Options' to extend its lifespan.
Cleaning: Do not use solvents or high-pressure cleaning equipment. Only use a soft damp cloth to wipe.
Regular inspection: Check the tightness of all plug and terminal connections and the integrity of cables at least once a year.
