Introduction
The TS-DIO24 is an 8-bit PC/104 expansion board that provides 24 digital I/O points. The I/O connector is an Opto-22 compatible interface that provides 16 I/O points configurable as input or output (24 mA as outputs) as well as 4 dedicated outputs capable of driving 48 mA and 4 dedicated outputs capable of sinking 1 Amp. The PC/104 interface decodes as registers in I/O space, the address is jumper selectable.
- 24 Digital I/O points
- Opto-22 compatible 50 pin connector
- 4 dedicated 48 mA ouputs, 4 dedicated 1 Amp outputs
- 16 programmable I/O points
- I/O address jumper selectable
- 4 interrupt capable inputs
- Up to 4 boards in a single system.
Hardware Configuration
Pin 1 has a 1 near the pin. All odd pins are on the same side, and all even pins are on the other side.

Product Notes
FCC Advisory
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used properly (that is, in strict accordance with the manufacturer's instructions), may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class A digital device in accordance with the specifications in Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the owner will be required to correct the interference at his own expense.
If this equipment does cause interference, which can be determined by turning the unit on and off, the user is encouraged to try the following measures to correct the interference:
Reorient the receiving antenna. Relocate the unit with respect to the receiver. Plug the unit into a different outlet so that the unit and receiver are on different branch circuits. Ensure that mounting screws and connector attachment screws are tightly secured. Ensure that good quality, shielded, and grounded cables are used for all data communications. If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions. The following booklets prepared by the Federal Communications Commission (FCC) may also prove helpful:
How to Identify and Resolve Radio-TV Interference Problems (Stock No. 004-000-000345-4) Interface Handbook (Stock No. 004-000-004505-7) These booklets may be purchased from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402.
