Fully compatible as its ISA-bus product
All the specifications, connectors, pin-assignments, registries format are the same. Users can upgrade their system into PCI bus without change any existed wiring system.
For the existed Windows application program:
Users just need to remove the PCL-730/733/734 via the 'Device
Manager', then install the PCI-1730/1733/1734 for instead (the device number must be the same). After that, user's original windows application program can work with PCI-1730/1733/1734 properly.
For the existed DOS application program:
Users just need to add some statements (to get the PCI bus PCI-
1730/1733/1734 card's address and IRQ information) from our PCI-
1730/1733/1734 DOS example program into their original DOS application program. After that, user's original DOS application program can work with PCI-1730/1733/1734 properly.
Robust Protection
The PCI-1730/1733 digital input channels feature a robust isolation protection for industrial, lab and machinery automation applications. It durably withstands voltage up to 2,500 V
DC
, preventing your host system from any incidental harms. If connected to an external input source with surge-protection, the PCI-1730/1733/1734 can offer up to a maximum of 2,000 V
DC
ESD (Electrostatic Discharge) protection. Even with an input voltage rising up to 70 V
DC
, the PCI-1730/1733 can still manage to work properly albeit only for short period of time.

Reset Protection Fulfills Requirement for Industrial Applications
When the system has undergone a hot reset (i.e. without turning off the system power), the PCI-1730/1734 can either retain outputs values of each channel, or return to its default configuration as open status, depending on its on-board jumper setting. This function protects the system from wrong operations during unexpected system resets.
Plug-and-Play Function
The PCI-1730/1733/1734 is a Plug-and-Play device, which fully complies with PCI Specification Rev 2.2. During card installation, there is no need to set jumpers or DIP switches. Instead, all bus-related configurations such as base I/O address and interrupt are automatically done by the Plug-and-Play function.
Board ID
The PCI-1730/1733/1734 has a built-in DIP Switch that helps define each card’s ID when multiple PCI-1730/1733/1734 cards have been installed on the same PC chassis. The board ID setting function is very useful when users build their system with multiple PCI-1730/1733/1734 cards.

Default configuration
Setting the time to reset the 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-1730 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-1730 is disconnected, the digital output channel’s initial power-on state will be "OFF".

Isolated Digital Output
Each of the 16 isolated digital output channels comes equipped with a darlington transistor. Every eight ouput channels share common emitters and integral suppression diodes for inductive load, actived by connecting PCOM to VDD. (Channels 0~7 use PCOM0. Channels
8~15 use PCOM1.)
If the external voltage (5~40 V) is connected to each isolated output channel (IDO) and its isolated digital output turns on (200 mA per channel maximum), the card's current will sink from the external voltage. The current through each EGND should not exceed 50 mA.
If the current for all channels combined exceeds 150 mA, return the current to the external voltage through CN6. The following figure shows how to connect an external output load to the card's isolated outputs.

Appendix C. Register Structure and Format
C.1 Overview
The PCI-1730/1733/1734 is delivered with an easy-to-use Advantech
Device Drivers for user programming under the Windows
2000/95/98/ME/NT/XP operating system. We advise users to program the PCI-1730/1733/1734 by using the Advantech Device Drivers provided by Advantech to avoid the complexity of low-level programming by register.
The most important consideration in programming the PCI-
1730/1733/1734 the register level is to understand the function of the card's registers. The information in the following sections is provided only for users who would like to do their own low-level programming.
C.2 I/O Port Address Map
The PCI-1730/1733/1734 requires 16 consecutive addresses in the PC's
I/O space. The address of each register is specified as an offset from the card's base address. For example, BASE+0 is the card's base address and BASE+6 is the base address plus six bytes.
The table C-1 shows the function of each register of the PCI-
1730/1733/1734 or driver and its address relative to the card's base address.
