procedures on how to transfer applications by using

pass-through.

DH+ Terminal Connections

This section describes connections for the DH+ PanelView terminals

including:

• DH+ ports

• typical DH+ system configuration

• making DH+ connections

DH+ Terminal Ports

The DH+ versions of the PanelView terminals (catalog numbers

ending in 8) have a DH+ port and an RS-232 port.

Use the DH+ port to:

• communicate with a PLC-5 controller on the Allen-Bradley DH+

link via the processor’s DH+ port.

• communicate with an SLC 5/04 controller (Channel 1 port) on

the Allen-Bradley DH+ link via the processor’s DH+ port.

• communicate with a ControlLogix controller on the

Allen-Bradley DH+ link via the 1756-DHRIO module.

• transfer applications over the DH+ link from a computer with a

DH+ connection.

TIP

If the terminal is the last device on the link, connect a 1/2 watt

terminating resistor across terminals 1 and 2. The value of the

resistor depends on the DH+ baud rate:

• for 57.6 kilobaud and 115.2 kilobaud, use a 150-ohm resistor

• for 230 kilobaud, use an 82-ohm resistor
