Declaration of Conformity
FCC Class A
This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause interference in which case the user
is required to correct interference at his own expense.
This product has passed the CE test for environmental specifications when shielded cables are used for external wiring.
We recommend the use of shielded cables. This kind of cable
is available from Advantech. Please contact your local supplier for ordering information.
The Advantech PCI-1734 is a 32-channel isolated digital
output card for the PCI bus. For easy monitoring, each isolated digital input channel is equipped with one red LED,
and each isolated digital output channel is equipped with one
green LED to show its ON/OFF status. The PCI-1734 provides specific functions for different user requirements.

Startup Manual
1. 1. Turn off your computer and unplug the power
cord and cables. TURN OFF your computer
before installing or removing any components on
the computer.
2. Remove the cover of your computer.
3. Remove the slot cover on the back panel of your
4. Touch the metal part on the surface of your computer
to neutralize the static electricity that might be on
your body.
5. Insert the PCI-1734 card into a PCI slot. Hold the
card only by its edges and carefully align it with the
slot. Insert the card firmly into place. Use of excessive force must be avoided; otherwise, the card might
be damaged.
6. Fasten the bracket of the PCI card on the back panel
rail of the computer with screws.
7. Connect appropriate accessories (37-pin cable, wiring
terminals, etc. if necessary) to the PCI card.
8. Replace the cover of your computer chassis. Re-connect the cables you removed in step 2.
9. Plug in the power cord and turn on the computer.

Switch and Jumper Settings
The PCI-1734 card has one jumper setting.
Isolated Digital Output Connections
Setting the time to reset digital outputs
Some users will want the capability of clearing each
digital output when the system (or PC) issues a reset
signal on the PCI bus. Some users will want to clear
their digital outputs only as part of system power-on.
The PCI-1734 satisfies both these needs by providing
jumper JP2. Depending on the application, this capability may allow digital outputs to be “OFF” without
requiring a complete shutdown of processes controlled
by the card.
Complete loss of power to the chip clears the chip
memory. Thus, no matter how JP2 is set, if the power to
the PCI-1734 is disconnected, the digital output channel’s initial power-on state will be “OFF”.
Each of the 32 isolated digital output channels comes
equipped with a darlington transistor. Every eight output channels share common emitters and integral suppression diodes for inductive load, activated by
connecting PCOM to VDD. (Channels 0 ~ 7 use
PCOM0. Channels 8 ~ 15 use PCOM1. Channels 16 ~
23 use PCOM2. If the external voltage source (5~40 V)
is connected to each isolated output channel (IDO) and
its isolated digital output turns on (200 mA max./ch),
the card's current will sink from the external voltage
source. The current through EGND should not exceed
4.8 A. If the current for all channels combined exceeds
2 A, CN2 must be connected to the external ground to
share the extra current. The following figure shows how
to connect an external output load to the card's isolated
