IMPORTANT NOTICE

Dear Customer:

We are in the process of changing the standardization of screws from slotted head to
phillips headt The new screws will also be black or stainless steel instead of zinc.

If some of the screws in your kit do not match the description in the Manual, use the
screws that match the size, thread and length of the description as shown in the
following example.

Thank you,

WARNING

This equipment has been verified to comply with the
limits for a Class B computing device, pursuant to Subpart
Iof part 15 of FCC Rules.

This equipment generates and uses radio frequency energy
for its operation and if not installed and used properly,
that is, in strict accordance with the instruction manual,
may cause interference to radio and television reception.
It has been type tested and found to comply with the RF
emission limits for a Class B computing device which is
intended to provide reasonable protection against such in-
terference in a residential installation. However, thereis

no guarantee that interference will not occur in a particu- '

lar installation. If this equipment does cause interference

to radio or television reception, which can be determined ~

by turning the equipment off and on, the user is encour-
aged to try to correct the interference by one or more of
the following measures: '

If additional help is needed, consult th

- Move the equipment away from the receiver
being interfered with.

- Relocate the equipment with respect to the
receiver.

, - Reorient the receiving antenna,

INTRODUCTION

The Heathkit Model GD-1530 is a computer Interface
device which allows you to operate your BSR X-IO
modules from a computer having an RS-ZSZC out-
put.

/

A
With the RSZ3Z/BSR Interface, you can write a pro-
gram on your computer to control various appli-
ances, lights, and other devices controlled by mud-
ules in your BSR X-10 Control System.

Your computer system must be equipped with an
RS-232C Serial Interface Port [no protocol required
or available) capable of a baud rate between 110
baud and 2400 baud to work correctly with the GD-
1530 Interface. "

Programming syntax and simple program examples
are provided in the Appendix at the back of this
Manual. You may develop more sophisticated pro-
grams for your own applications, or you may find
programs available in various users groups.

WARNING

Federal Communications Commission requirements prescribe verification of computing devices in
Part 15 Subpart I of the rules and regulations. This computing device will meet these requirements
when constructed in strict accordance with the instructions in this manual, using only components
and materials supplied with the kit or the exact equivalent thereof.

PARTS

Resistors are identified in Parts Lists and steps by
their resistance value in 0 (ohms), k0 [kilohms], or
M!) (megohms). They are usually identified by a color
code and four or five color bands, where each color
represents a number. These colors (except for the last
band, which indicates a resistors tolerance] will be
given in the steps in their proper order. Therefore, the
following color code is given for information only.
NOTE: Occasionally, a precision or power resis-
tor may have the value stamped on it.

Capacitors will be called out by their capacitance
value in uF (microfarads) or pF (picofarads) and type:
ceramic, Mylar", electrolytic, etc. Some capacitors
may have their value printed in the following man-
ner:

EXAMPLES :

1511K = 15 x 10 = 150 pF
759 = 75 x01 = 7.5 pF

NOTE: The letter R" may be used at times to signify a

First d'Q" °_f decimal point: as in: 2R2 = 2.2 (pF or [.LF).
capacttors value: 1 1 5 1 K

PARTS LIST

Unpack the parts and check each part against the fol-
lowing list. The key numbers correspond to the num-
bers on the Parts Pictorial (Illustration Booklet, Page
1]. Any part that is packaged in an individual en-
velope with a part number on it should be placed back
in the envelope after you identify it imiil it is called
for in a step. Do not discard any packing materials
until all the parts are accounted for.

Some parts are marked with a 171-" or 172- pack-
aging number. These numbers are used for packaging
purposes only and do not appear in the Manual Parts
List. &

To order a replacement part, always include the
PART NUMBER. Use the Parts Order Form furnished
with the kit. If one is not available, see Replacement
Parts inside the rear cover. For prices, refer to the
separate Heath Parts Price List.
