OVERVIEW
The AVINTCDR is an RS232 or RS485 interface to an MLS Connect
Digital Intelligent LCM (or CD Box) which expands the scope of the
MLS system such that it can be controlled via AV equipment.
The AVINTCDR is compatible with the RS232/RS485 protocol used
by AV systems (Dynet protocol).
When the interface receives a command from the AV system, LED1
will flash RED then Green. The decoded signal is then sent to the CD
Box where it is translated and forwarded on to the MLS Bus.
A command can recall scenes 1 to 6 of a zone in the range 1 to 100.
INSTALLATION
Only suitably qualified personnel should install this equipment.
The AVINTCDR is supplied in a protective enclosure which should be
placed where it is readily accessible for commissioning purposes.
CONNECTION
The AVINTCDR requires 12V DC power which it obtains from the CD
Box. Connection to the CD Box is achieved by a standard RJ45 patch
lead, up to 10 metres, plugged into any detector port.
For RS485 Mode:
Connections at the 9-way D-type should be wired to the AV system
preferably at the end of the data line (due to the terminal size of the
supplied connector) using suitable screened twisted pair cable
(recommend stranded). For 120 Ohm end of line termination ensure
that the ‘Terminator’ jumper (JP7) is fitted.
For RS232 Mode:
Connections at the 9-way D-type should be wired to the AV system
using suitable RS232 data cable.
Changing the jumpers will require opening the enclosure.
Please use a slotted screw driver to gently prise the enclosure.

Factory Default Jumper Settings Summary
Option to provide 12V to D type connector
When JP5 is made the AVINTCDR can provide 12V DC to pin 9 of the
D-Type connector. This function is only available in RS232 mode.
LED Status:
LED1 Red = Receiving signal from AV system
Green = Received Data Ok
LED2 Red = Error
Green = Ready to receive signal

Termination Resistors for RS485 Mode
Operation of RS485 systems requires that the data lines be
terminated. Provision is made to connect this 120R terminator using
jumper, JP7.
COMMUNICATION MODES
Format:
9600 Baud, 8 bit data. 1 start bit, 1 stop bit, no parity.
RS232 Mode 9-Way Port Info;
In RS232 mode connections are made via the 9-way D-type
connector on the interface. The onboard connector is female and
configured as a DCE.
JP7 Link Function
PROTOCOL INFORMATION
The interface uses a subset of the Dynet 8-byte strings.
The AVINTCDR does not transmit a reply and there are no
downloadable settings.
AV system configuring
The AV system needs to transmit packets to communicate the desired
scene and the target MLS zone. This will be in the format of the Dynet
protocol. The second byte (Byte1) is the zone and fourth (Byte3) will
be the scene.
8-byte packet. Checksum = Negative 8 bit 2’s complement sum of
bytes 0-6. All numbers in hexadecimal, example zone 12 will be 0C.
XX = Not applicable although normally zero.

RS485 Mode 9-Way Port Info;
In RS485 mode connections are made via the 9-way D-type
connector on the interface. The onboard connector is female and the
supplied mating socket has screw terminals. (Do not over tighten the
screws.)

Example: Select Scene 4 in MLS zone 1
[1C] [01] [64] [03] [00] [00] [00] [7C]
Note: Many AV/Architectural dimming systems like to use scene 4 for
“OFF”. If desired, the MLS ystsem can be aligned with that by simply
programming scene 4 in the MLS system to mean “OFF”.
