OPERATIONS

In Slave Mode the Remote Display will wait for commands and
data from the Serial Bus.

In Host Mode the Remote Display will send data automatically and
continuously into the Serial Bus.

When used in RS-485 Mode, the device must be accessed with an
appropriate Address Value.

Latched Mode: Alarm remains latched until reset. To reset already
latched alarm select any menu items and then press “up” or “down”
button.

Write alphanumeric characters to the Remote Display
from the computer (Display in Slave Mode)

a) Single Remote Display: (RS232) write 4(6) characters, then

CR (carriage return)

b) Multiple Remote Display: (RS485) write *, device address

(2 digit), CR, 4(6) characters, then CR

c) How to display time format or colon “:”, ex: 12:30,

from keyboard enter: 1230 !

Host mode uses Newport product protocols

Process V

Press dto request “Process” Value.

a) RS-232 Mode, will send: *X01
b) RS-485 Mode, will send: *01X01

Peak Value (Display on Host Mode)

Press bto request “Peak” value:

a) RS-232 Mode, will send: *X02 (or *X03 †)
b) RS-485 Mode, will send: *01X02 (or *01X03 †)

Display Color Setup (Alarm Setup)

This menu allows the user to select the color of the display in
normal conditions and when alarm is triggered. If user wants the
Display to change color every time when both Alarm 1 and Alarm 2
are triggered, the Alarm values should be set in such a way that
Alarm 1 is always on the top of Alarm 2 value, otherwise value of
the Alarm 1 will overwrite value of Alarm 2 and Display color would
not change when Alarm 2 is triggered.

Example 1:

Alarm 1 setup:

“ON”, Alarm Mode High “A1HI”, Alarm High

Value “HI-1”=400, Alarm Color “A1CR”=Amber
Alarm 2 setup:

“ON”, Alarm Mode High “A2HI”, Alarm High

Value “HI-2”=200, Alarm Color “A2CR”=Red
Normal Color:

“NO.CR”=Green

Display colors change sequences

Mounting Remote Display Through Panel:

1.

Using the panel cutout diagram shown above, cut an opening in
the panel.

2.

Remove two screws at the back of remote display to remove back

cover.

3.

Insert the unit into the opening from the front of the panel, so the
gasket seals between the bezel and the front of the panel.

4. Align back cover to remote display and reinstall screws.

Mounting Remote Display on Bail:

1. Use the Remote Display template to mark the location of

mounting screws on the flat surface.

2.

Be sure to leave enough room around the bail (as noted on the

template drawing) to allow for removal and rotation of the display.

3. The display can be rotated to 12 positions for the best

viewing angle.

Disassembly Instruction:

Warning: Disconnect all ac power from the unit before
proceeding.

1.

Remove all wiring connections from the rear of the instrument, by
unplugging the power and input connectors.

2.

Remove two screws at the back of remote display and back cover.

3. Remove the Remote Display from the panel.

4. To remove the Remote Display from the bail, spread

mounting ears.

RD4 AND RD6 REMOTE DISPLAY

DESCRIPTION:

The RD4 and RD6 are 4(6) digit master/slave displays providing
remote readout from instruments such as programmable controllers,
digital panel meters and other instruments with serial output. Two
communication interfaces are supported in Remote Display: RS-232
and RS-485 and can be programmed through front panel buttons.

The RD4/RD6 remote display can be mounted in a 1/8 DIN panel
cut-out or surface mounted with the included bale.

The Remote Display features big bright 21mm (0.83”) and 17.3mm
(0.68”) 9 segment LED’s that can be programmed to change color
between Green, Amber, and Red to indicate alarms.

Serial Communications can be made to an RJ-11 jack or screw
terminals. In the Slave mode, the RD4/RD6 can be used for
displaying Alphanumeric characters from a computer.

Power is supplied from 10 to 36 Vdc power supply or AC adapter
120/240 Vac to 12 Vdc (200 mA).

Compatible Host device must feature serial RS232 or RS485 output.

SAFETY:

• The instrument is a panel mount device protected in
accordance with

EN61010-1:2001

.

•

This device does not provide safety isolation. Therefore,
always use a Safety Agency Approved DC power source.

EMC:

• Whenever EMC is an issue, always use shielded cables.

• Never run signal and power wires in the same conduit.

• Use signal wire connections with twisted-pair cables.

• Install Ferrite Bead(s) on signal wire close to the instrument if
EMC problems persist.

Wiring RS-485 Interface.

The RS-485 standard (multipoint) allows a computer, one or more
devices and Remote Displays (up to 32) to be connected using a
two-wire connection (half-duplex) plus a common wire to connect
to the shield of the cable. It is recommended to use shielded cable
with one twisted pair for EMI noise protection.

Connections to the computer are optional.
