RDP100 Remote Display Panel

Overview

Vaisala Remote Display Panel RDP100 is a digital display that shows the live
measurement of one or two environmental m easurement parameters, supplied
by a compatible Vaisala measurement instrument. RDP100 shows the data
from the instrument as-is - there are no adjustments or calibrations on the
display side. The parameter(s) to be displayed are select ed using D IPswitches
on the display's component board.

The housing of the RDP100 is designed t o be recessed into a wall, wit h only the
front cover visible. There is no user interface on t he outside of the RDP100.

Note: Datasheet isavailable from the product page at

www. vaisala.com/ rdp100.

Serial Port Settings

RDP100 and t he measuring inst rument communicate on the RS-485 line using a
Vaisala proprietary protocol. There must be only one RDP100 and one
compatible inst rument on the RS-485 line - no other devices. The serial port
settings of the connected measuring instrument must be:

l 19200bits per second
l 8 data bits
l no parity bit
l one stop bit

Note: The requiredsettings are t he factory default s ettings for all of t he
compatible inst ruments. However, if you have changed the serial port
settings, y ou must change them back to 19200-8-N-1before RDP100 c an
read the instrument.

There are no requirements for the serial port operating mode (f or example,
STOPmode), address, or measurement message format of the measuring
instrument.

Power Supply and Wiring Considerations

RDP100 requires a regulated 12 ... 28 VDC supply voltage. To simplify t he
wiring and avoid ground loops, use only a single power supply to power both the
RDP100 and t he measurement instrument. The recommended wiring
arrangement depends on the instrument that is connected:

l HMDW110 series t ransmitters are designed t o supply operating

power to the RDP100. For wiring instructions, see sect ion Wiring
HMDW110 with RDP100 on page9.

l The rest of the supported instruments s houldbe powered through the

RDP100. For wiring instructions, s ee section Wiring on page8.

2 = Display element (do not touch).
3 = Direction arrow, point up duringinstallation.
4 = Electronics housing.
5 = Stainless steel front cover.
6 = DIPswitc hes f or parameter selection and unit select ion.
7 = Power pass-through jumper. Connecting t he jumper t o position 1-2 allows

the s upply voltage to pass through the RDP100 unregulated. Connecting
the jumper to position 2-3 regulates the pass-through voltage to 7.5 VDC.

8 = Mounting screws (4 pcs).
