The World Leader in High Performance Signal Processing SolutionsThe World Leader in High-Performance Signal Processing Solutions Adding a Parallel Port to a Computer
Problem Older ADI eval boards & software require a parallel port, yet most new PCs dont come with a parallel port Software requires parallel port to be at a legacy address: 0x378, 0x278, and 0x3BC As far as we know, USB to Parallel port adapters do not work. Weve heard from many customers who have tried and were unsuccessful. Solution Find a computer with a parallel port Add a parallel port to your computer Re-write the evaluation software source code Source code is usually available upon request, however ADI cannot provide help or support for this.
Adding a Parallel Port to Computer Desktop PCI or PCIE card (not researched here) Plugs into PCs motherboard Should easily be configured to work as legacy parallel port Laptop Laptop docking station (also not researched here) Not all Laptops can use a docking station Usually specific to the laptop brand and/or model More expensive than add-on card Provides additional connectors, not just parallel port Good for fixed workstation Also should easily be configured to work as legacy parallel port Add-on card (researched here) Not all cards can be configured to work as a legacy parallel port Highly portable
Laptop Add-on Cards Add-on Cards are either PC Card (aka PCMCIA) or ExpressCard.PC Card ExpressCard Slots on the laptop may look the same, however PC Cards will not fit into ExpressCard slots and vice versa. If looking at ExpressCards, make sure it communicates to the motherboard via PCIE instead of USB 2.0. Remember, USB communication does not work.
Laptop Add-on Cards PC Cards tested by ADI: Startech CB1PECP Syba SD-PCB-1P Quatech SPP-100 Only working solution was Quatech because it can remap to a legacy parallel port address. Quatech also makes an ExpressCard option, the SPPXP-100 Both Quatech cards support 32-bit and 64-bit Windows XP, Vista, and 7. SPP-100 PC Card costs about $100 ( Google Shopping) Google Shopping SPPXP-100 ExpressCard costs about $115 (Google Shopping)Google Shopping
Before Buying a Card… Check if PC resources are already taken. Open Device Manager In the View menu select Show Hidden Devices Go back into the View menu and select Resources by Type Expand the category Input/output (IO) Do any of the ranges include 00000278 and 00000378? If both are taken, getting a parallel port card will not work.
Installing Quatech Card While computer is on, insert the card into the card slot (slot is plug- n-play) When the Found New hardware Wizard pops up, select Install from a list or specific location
Installing Quatech Card Let the Wizard search for drivers on the CD or point it to drivers downloaded from http://www.quatech.com/http://www.quatech.com/ Click finish when complete
Changing Port Address of Quatech SPP-100 Open Device Manager, expand Ports (COM & LPT) and double click on Quatech SPP-100 PCMCIA Parallel Port.
Changing Port Address of Quatech SPP-100 Go to Resources tab and un-check Use Automatic Settings. Change the configuration to one with an I/O Range that starts with 0378 or 0278, has an IRQ interrupt, and does not conflict with existing hardware.
