CHAPTER 1 Introduction

The Standalone PCI Interface Package is designed for those applications using a single or limited number of test chambers with no intentions for future expansion. Unlike the modular interface packages, there is no external cabinet and power supply. Connections are made directly to the "standalone" card, which plugs in to a compatible computer. Inputs and outputs are contained on the single card that also provides timed interrupts as required by MED-PC software.

The Standalone PCI Interface Package is available with either 4 Inputs / 8 Outputs or 8 Inputs / 16 Outputs. This manual covers both packages.

WARNING: Do not activate 28 Volts DC with any device connected to the interface card before reading this manual. Certain devices are designed to operate from a short pulse and may be damaged if held on for any extended period of time. Until the function of this card and the software controlling it are understood, it is possible for an output to be held on indefinitely.

The Port System

The port address is hardwired to port 780 for inputs and port 792/793, offset 0 for outputs. MED-PC users should note that in MPC2INST, the MED-PC installation program, the card is the same as a SmartCtrl module. Select DIG-715/716 or DIG-716B depending on the package purchased.

CHAPTER 2 System Overview

4 Input, 8 Output System

This package includes one DIG-750D SmartCtrlTM_{PCI card, one SG-716 SmartCtrl}TM connection panel and one SG-501 28-Volt power supply.

The cables included with the package are one SG-210CB control cable, and two SG-750D power adapter cables. A 25' (7.6 m) power cable (SG-210CP-25) is supplied for the first test station in each group of four. Subsequent stations are daisy chained together with 8' cables (SG-210CP-8).

This system provides four inputs and eight outputs that may be assigned any function and connected to any accessory on the test chamber.

This package includes one DIG-750D SmartCtrlTM_{PCI card, one SG-716B SmartCtrl}TM connection panel and one SG-508 28-Volt power supply.

The cables included with the package are one SG-210CB control cable, and two SG-750D power adapter cable. A 25' (7.6 m) power cable (SG-210CP-25) is supplied for the first test station in each group of four. Subsequent stations are daisy chained together with 8' cables (SG-210CP-8).

This system provides eight inputs and sixteen outputs that may be assigned any function and connected to any accessory on the test chamber.

CHAPTER 3 Input Settings

The input settings are selected using the dipswitches labeled SW1 and SW2 located in the upper right corner of the DIG-750D circuit board. The location of the switches is shown in Figure 3.1.

Transition and Level Input Settings

The row of switches (SW1) used for this setting can be set to L for Level or T for Transition. The default switch placement is Transition, as shown in Figure 3.1.

Transition

This setting provides a single input, no matter how long the input is held. When used with a response lever, for example, this requires the animal to both press and release the lever before another response could be detected. The input may occur on either the press or the release depending on the switch contact (normally open or normally closed) and the input setting (Normal or Invert). Because the input of the card is filtered against switch bounce and latched until polled by the computer, even the shortest contact (or contact break if in Invert mode) will not be missed.

(8)

Level

This setting results in an input being detected each time the card is polled, for as long as the input is maintained. (In MED-PC® this occurs on each interrupt and is determined by the resolution setting when Med PC is installed. See the MED-PC® manual for details). This may be desirable when using photobeams, or when timing how long a response lever is held.

Normal and Inverted Input Settings

The row of switches (SW2) used for this setting are labeled + for Normal and - for Inverted. The default switch placement is Normal (+), as shown in Figure 3.1.

Normal

This setting is designed to work with a normally open contact, such as those found in response levers, and will cause an input to occur when the response lever is pressed or the switch contact is closed.

Invert

This setting is designed to work with normally closed contacts, such as those found in pigeon keys, and produces a response when the key is pressed. This setting should be used if an input should occur when a normally open response lever is released or a switch contact is opened. Also use with photobeam inputs if an input is desired when the beam is uninterrupted instead of broken.

CHAPTER 4 Wiring Instructions

The wiring instructions vary slightly between the 4 Input, 8 Output System and the 8 Input, 16 Output System. Refer to the cable guide for illustrations of each cable.

WARNING: Do not activate 28 Volts DC with any device connected to the interface card before reading this manual. Certain devices are designed to operate from a short pulse and may be damaged if held on for any extended period of time. Until the function of this card and the software controlling it are understood, it is possible for an output to be held on indefinitely.

1. Using the SG-210CB cable, connect the 25-pin connector on the bottom of the SG-716 Connection Panel to the 25-pin connector on the DIG-750D card.

2. Using an SG-750D adapter cable and the 8’ SG-210CP cable, connect any of the 28 Volt connectors on the SG-716 Connection Panel to either of the power inputs on the DIG-750D card.

3. Using the other SG-750D adapter cable and the 25’ SG-210CP cable, connect the other power input on the DIG-750D card to the 28 Volt connector on the SG-501 power supply.

4. Using the included AC power cord, connect the SG-501 power supply to a standard wall outlet.
