2. Wiring RS-485 Interface.

The RS-485 standard (multipoint) allows a computer, one or more
devices and Big Displays (up to 32) to be connected using a two­wire 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.

Example 2:

Alarm 1 setup:

“ON”, Alarm Mode Low “A1LO”, Alarm Low
Value “LO-1”=100, Alarm Color “A1CR”=Amber
Alarm 2 setup:

“ON”, Alarm Mode LO “A2LO”, Alarm High
Value “LO-2”=300, Alarm Color “A2CR”=Red
Normal Color:

“NO.CR”=Green

Display colors change sequences:

DESCRIPTION:

The iLD24 is a 4-digit master/slave display providing remote readout
from instruments such as programmable controllers, digital panel
meters and other instruments with serial output. Communication
interfaces supported are RS-232 or RS-485 standards. Both
RS-232 or RS-485 are programmable through front panel buttons.

The Big Display features a large three color programmable display
with the capabitity to change color every time an Alarm is triggered.

SAFETY:

• The instrument is a panel mount device protected in
accordance with EN61010-1:2001.

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.

MOUNTING

Mounting Big Display Through Panel:

1.

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

2.

Remove six screws at the back of Big 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

Big Display

and reinstall screws.

WIRING

1. W

iring RS-232 Interface.

The RS-232 standard (point-to-point) allows a single device to be
connected to the

OPERATIONS

1. Peak V

alue

(Display in Host Mode)

Press bto request “Peak” value:

a) RS-232 Mode, will send:

*X02 (Interface DRNT), or *X03 (Interface DRNP)

b) RS-485 Mode, will send:

*01X02 (Interface DRNT), or *01X03 (Interface DRNP)

In the examples for RS-485 it is assumed that the
device address is 01.

2. V

alley Value (Display on Host Mode)

Press cto request “Valley” value.

a) RS-232 Mode, will send:

*X03 (Interface DRNT), or *X04 (Interface DRNP)

b) RS-485 Mode, will send:

*01X03 (Interface DRNT), or *01X04 (Interface DRNP)

3. Process Value (Display on Host Mode)

Press dto request “Process” Value.

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

4. Write alphanumeric characters to the Big Display
from the computer (Display in Slave Mode)

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

CR (carriage return)

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

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

5. 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:
