IR30 DIM
This is a simple unit with make or break double push buttons, used for pulse dimming. Holding
down the buttons will ramp the dimming. An external DC voltage is required.
The IR30 dimmer may be connected directly to AUX in of JB70D1. DIM Up on CN1 16/18, Dim Dn
on CN2 06/08.

How to connect IR30 DIM to CD401-MR
Note
: Due to optcouplers inside the compact, an external DC source is
necessary on the DIM Up A/B and DIM Down A/B inputs.

IR31 DIM
The CD402 may be dimmed by NMEA DDC commands. The DDC command is input to the NMEA
input of JB70D1 Electronic unit.
The IR31taking up to 2 NMEA lines and multiplexing onto it a DDC or Proprietry message
each time a button is pushed
Auto mode with internal or external light sensor the unit can be made to send
messages when the correct light conditions are reached (User adjustable)

connecTion
The JB70D1-XX system has 1 NMEA isolated input and 4 output ports driven separately from a single
com port, each capable of delivering 20mA. These are marked in blue and can be programmed to
give out a number of messages. In addition, the LAN port can be used to provide the same formats
using the IEC61162-450 standard. However, it should be noted that this port will normally also send
out proprietry messages with information to the CD401CU-XX control unit. Approved messages are
sent at a 1 second interval, and are marked with the ‘VD’ identifier. Data is sent at 4800 baud, 8
data bits, 1 stop bit. The inputs require 2ma when the voltage is limited to 2V. Generally the inputs
use 2.5 mA if available.
