IntelliFlex™ RF Remote Control by Draper Page 2 of 2

A Note on Interference

This equipment has been tested and found to comply with the limits for a

class B digital device, pursuant to part 15 of the FCC Rules. These limits

are designed to provide reasonable protection against harmful interference

in a residential installation. This equipment generates, uses and can radiate

radio frequency energy and if not installed and used in accordance with

the instructions, may cause harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular

installation. If this equipment does cause harmful interference to radio or

television reception, which can be determined by turning the equipment off

and on, the user is encouraged to try to correct the interference by one or

more of the following measures:

➀

Reorient or relocate the receiving antenna.

➁

Increase the separation between the equipment and receiver.

➂

Connect the equipment into an outlet on a circuit different from that to

which the receiver is connected.

➃

Consult the dealer or an experienced radio/TV technician for help.

Operation with non-approved equipment is likely to result in interference to

radio and TV reception. The user is cautioned that changes and modiﬁ cations

made to the equipment without the approval of manufacturer could void the

user’s authority to operate this equipment.

Radio Codes

Radio Frequency is 418 MHz ± 75 KHz, on-off keying.

All times in the following description are nominal with a tolerance of ± 5%,

however, all times must change proportionally.

A packet of data consists of:

A start sequence, 20 address bits, and 16 data bits. The packet is similar to

that used by the Holtek brand of data encoder chips.

The Start sequence consists of:

471 µs on, 471 µs off, 973 µs on, 973µs off, 471 µs on, 471 µs off, 973 µs

on, 973 µs off, 471 µs on.

Address & data bits consist of:

A “0 bit” being deﬁ ned as 471 µs off, 973 µs on,

A “1 bit” being deﬁ ned as 973 µs off, 471 µs on.

The start sequence plus the address and data bits make a packet 57 msec

long. There must then be a pause of 17 msec before the packet is transmitted

again.

The address is encoded in 20 bits (A0 = least signiﬁ cant bit, A8 = most

signiﬁ cant bit of 512 possible addresses):

A0 0 A1 0 A2 0 A3 0 A4 A5 A6 A7 A8 1 1 1 1 1 1 1

The button data is encoded in 16 bits (D0 = least signiﬁ cant bit, D7 = most

signiﬁ cant bit of 256 possible numbers):

1 D0 1 D1 1 D2 1 D3 1 D4 1 D5 1 D6 1 D7

The button data is converted into a command compatible with the “BUS”

connecting receiver controls together.

Splitter

Modular Jack Adapter

Modular Cable Coupler

Optional Cable Accessories

A Note on Wiring

The RF Receiver must be plugged in to an open "Eye" jack (see diagram on

page 1). All input devices connect using electrically straight 4-conductor

modular cable.

Please note: If you use standard telephone cable, you must ﬁ rst remove one

connector, turn it over and re-attach, to ensure that the cable is electrically

straight (see diagram below).
