INTRODUCTION
The Antex SX-5e, SX-6, SX-34 and SX-36 family of cards are ISA
bus audio “add-in” cards for the PC. They all incorporate DSP’s
(Digital Signal Processors), which allow the cards to do a variety
of audio formats. (MPEG, PCM16, MSADPCM, etc.) All cards are
dual device, which means they can operate on 2 hard drive files at
the same time. These cards operate at several fixed standard
sample rates: 8, 11.025, 16, 22.05, 32, 44.1, and 48 KHz. The
SX-5e and SX-6 are playback only cards, and the SX-34 and SX-
36 have playback and record capability. The SX-5e and SX-34
have unbalanced analog I/O and the SX-6 and SX-36 have bal-
anced analog I/O. Up to 4 cards may be installed into one com-
puter.
Software is provided for Win95/98, and WinNT. Software in-
cludes the “driver”, the Antex Demo application, Antex Mixer ap-
plication, and Antex VU Meter application. Contact Antex Techni-
cal Support or visit the Antex website (www.antex.com), for infor-
mation about DOS or Windows 3.11 drivers, or the Software De-
veloper’s Kit (SDK).
CARD INSTALLATION
Make sure the main power to your computer is OFF. You will
need a 16 bit/AT slot. If you are unfamiliar with the internal design
of your computer see its "Guide to Operations" manual for step by
step installation procedures. To avoid damaging the board or
your computer with static electricity:
1. Touch the metal of your computer chassis first to discharge
the static electricity from yourself before opening the antistatic
bag the Antex Card is packaged in.
2. Move around as little as possible. Don’t shuffle your feet on
carpet or move around in your chair.
3. Handle the card by the bracket and the edges. Try not to
touch the gold fingers or any of the parts on the board.
2
Set the board number with jumpers as shown below. If only one
board is being used, leave the jumpers off (sets to board number
one). When using more than one card in a computer, each board
must be given a different number by setting the jumpers differ-
ently on each card. Any model Antex Card may be used with any
other model Antex Card. All model Antex Cards use the same
jumper arrangement to set the board number.

The jumpers are oriented vertically so that they may be easily
changed without having to remove the card from the computer
slot if they should need to be changed later. These jumpers only
set the board number, allowing for more than one board in a com-
puter. They do not set interrupts.

I/O ADDRESSES AND INTERRUPTS
SX-5e, 6, 34, 35 & 36 I/O addresses and interrupts are software
selectable. The valid I/O addresses are:
180h, 220h, 280h, 300h, 320h and 380h
The valid interrupts are:
2, 3, 4, 5, 10, 11 and 12
Note that interrupts 3 and 4 are normally used by the computer’s
COM ports and will not be available. The interrupt and I/O ad-
dresses are selected at the time of software installation or auto-
matically by Windows 95/98.
________________________________________________
MAKING CONNECTIONS TO THE CARD
The more commonly used signals are connected to the card from
the rear of the computer using connectors on the card’s bracket.
Other connectors for auxiliary functions are single or dual row
male headers on the card itself. The pins on these connectors
are numbered as follows:
Dual row headers oriented vertically on the card start with pin 1 in
the upper left corner. Odd number pins continue down the left
column of pins. Even numbers go down the right column of pins,
with pin 2 being at the top.
Single row headers oriented horizontally on the card have pin 1 on
the left.
See the appendix for information on the mating connectors for the
single and dual row headers. Cables which connect to the DB9
connector on the SX-6, SX-35, and SX-36 are available from An-
tex. The following wiring diagrams are provided to make your own
cables. Antex recommends using shielded twisted pair cable for
4
balanced connections and shielded coax cable for unbalanced
connections. See the section “Balanced and Unbalanced Sig-
nals”.
