System

The TDT system provides a unifying interface for sending and receiving behavioral 

information from a behavioral control box without the need for the external devices 

from these other companies.
TDT provides a default set up that uses standard Molex pins, an External power 

source to drive high current and high voltage devices (such as feeders, water 

delivery systems, foot shock systems, etc) or to accept inputs from such devices. 

The hardware states of these particular interfacing devices are fixed and the BH32 

bank directions and logic levels must be configured to match (see “Digital I/O ” on 

page 17-19).

Configuration

 

Information can be sent and received from the Molex interface in the following ways.

Note:

Molex Banks A and B can be used as outputs and only outputs. Molex Bank D can 

be used as inputs and only inputs. The direction and logic level of each bank is 

configured through the BH32 web interface (See “Controller Configuration” on 

page 17-23).

Important!:

Attempting to drive an input from both the digital input and Molex connectors will 

damage the device.

only)

Configure the bank as an output. The Molex outputs are low when active. The digital 

output logic is the inverse of the Molex output logic.

(bank

Configure Bank D as an input. Active-Low means that when the Molex input is low, 

the value is 1. The digital output logic mirrors the Molex input logic.

Configure the bank as an input, to bypasses the internal processor and control the 

Molex lines directly. Molex output logic is the inverse of the digital input.

only

If the Molex connectors are not being used, then all four banks of digital I/O can 

be used to send receive signals with the UDP/Serial interface with no restrictions on 

bank direction.

Digital

 

I/O

 

The BH32 includes 32 bits of programmable I/O grouped in four 8-bit banks. Digital 

I/O lines are accessed via the Digital IO–1 and Digital IO–2 25-pin connectors on 

the back panel. Digital inputs 5V TTL inputs. Digital outputs are +5V. For 

pinouts, see “BH32 Technical Specifications” on page 17-30.

Status

 

Lights

A row of 32 status lights on the front panel report the state of the individual input/

output bits and are labeled to show banks A – D. When a bit is active, the 

corresponding bit light glows red.
