PDS System Recommendations

To install our software, your computer should meet the specifications. Our products have been tested using these system requirements. However, because computing environments and internet service vary so widely, these system requirements are provided without guarantee. Your computer performance will vary based on hardware configurations, network traffic, and local workstation settings.


Our software requires a tray-fed laser or inkjet printer that is compatible with the system requirements provided above. Laser and inkjet printers are also suitable if driver support is available for the associated operating system.


The MICR Image Reader works only with desktop versions, not OnDemand.

For SpeedCheck, ACS Technologies offers the following scanners to fit your needs. All scanners are remote deposit ready.
  • SpeedCheck Scanner Single-Scan — Scans and loads checks one at a time.
  • SpeedCheck Scanner 30 DPM — Scans multiple checks with speeds up to 30 documents per minute.
  • SpeedCheck Scanner 55 DPM — Scans multiple checks with speeds up to 55 documents per minute.
  • SpeedCheck Scanner 120 DPM — Scans multiple checks with speeds up to 120 documents per minute.

Monitors & DPI

For all software, ACS Technologies recommends using 17-inch monitors, which are designed at 96 DPI.

Widescreen monitors may cause some software to look different on a 17-inch monitor, unless DPI settings are modified.


We require a business-class router with Quality of Service ("QOS") Capability. This allows you to specify the priority of certain traffic to the Internet. For instance, all OnDemand traffic to the Internet for ACS, PDS, and HeadMaster uses port 491. Clients who have set priority for the required port for OnDemand traffic have found dramatic improvement in performance and reliability.

Your router needs to be able to handle a sufficient number of IP threads for the traffic generated by the maximum number of concurrent users. When calculating total Internet traffic, take into account: e-mail, Web browsing, uploading and downloading files, OnDemand, any video or audio streaming, and all other network use.

Internet Connection

OnDemand requires a response within 500 ms or 1/2 of a second. If the Internet lag time exceeds this limit, the connection can be lost, and the session will be disconnected. Below is a guide which outlines the number of concurrent users who can be supported at various broadband speeds when only OnDemand is running:

Kbps Upload/Download30300750150030006000
Mbps Upload/Download0.030.30.751.53.06.0

At the absolute minimum, the bandwidth for uploading and downloading must not be less than 30 Kbps per concurrent user. Ideally, your ISP's advertised connection speed should be significantly greater in order to keep users from being dropped during peak Internet times. Also, note that upload speed is equally important as download speed when using OnDemand.

We cannot guarantee that any particular DSL or cable connection to the Internet will perform satisfactorily due to the countless factors that may affect and degrade the performance of your connection.
CAUTION: ACS Technologies does not support OnDemand using a satellite broadband service. We have found that the latency in this service does not create a good experience.


As ACS Technologies moves more products and services to the Web, we require a high speed internet connection using the latest, stable version of Microsoft Internet Explorer®, Chrome®, Safari®, or Firefox®.

Microsoft End of Life Policy

ACS Technologies adheres to Microsoft's life-cycle policy for operating systems. As a system approaches its end-of-life date, we recommend upgrading your operating system. Once an operating system is no longer supported by Microsoft, we can no longer support that system. This does not mean that products will not work on a retired operating system, but it does mean that, should a problem occur that would require an update for a retired operating system, we cannot provide support assistance for clients using those operating systems.
