BH32 Behavioral Cage Controller
BH32
Behavioral
Cage
Controller
Overview
The BH32 Behavioral Cage Controller integrates neural signals with behavioral inputs
and outputs from standard behavioral cages; such as operant conditioning boxes. The
device acts as a network appliance that can be used over a LAN to control several
behavioral boxes or can be directly linked to a TDT RZ device for integration with
neural recordings. The device provides the end user with 32 I/O lines in banks of
eight. Each bank can be configured as inputs or outputs. End users can drive
standard 5 Volt devices or power the device with an external supply to deliver up to
30 Volts, 3 A.
Features
Molex
Pin
and
Socket
Connectors
The BH32 uses 1.57 mm Diameter Standard Molex Pin and Socket connectors on
the top panel. For pinouts, see “BH32 Technical Specifications” on page 17-30.
Power
The BH32 logic board is powered by either a 6-9V, 3A center-negative adapter
connected to the power input on the back panel of the device or by Power over
Ethernet (PoE) through the Ethernet Port (see “Ethernet Port” on page 17-20).
The BH32 Molex outputs can be driven by either the same power source as the
logic board (5V) or by an external power source connected to the ‘External Power’
connectors on the top of the device. The ‘External Power’ connectors allow you to
drive higher voltages/currents to external devices that require it, One connector can
be used to input a 5-30V, 3A external power source that is shared among all
Molex output connectors. A toggle switch on the back panel of the device determines
which power source is used for the Molex outputs. The Molex connector outputs are
always Active-Low.
