a. Method 1, For Load Resistance > 250 Ohms.

Refer to Figure 7-1 and the following steps to

connect the HART Communicator to a signal line

250 ohms or more of load resistance.

Explosions can result in death or serious

injury. Do not make connections to the

HART Communicator's serial port, 4-

20 mV signal line, or NiCad recharger jack

in an explosive atmosphere.

Using the supplied lead set, connect the HART

Communicator in parallel to the Oxymitter 4000.

Use any wiring termination points in the analog

output 4-20 mA signal line.

b. Method 2, For Load Resistance < 250 Ohms.

Refer to Figure 7-2 and the following steps to

connect the HART Communicator to a signal line

with less than 250 ohms load resistance.

Explosions can result in death or serious

injury. Do not make connections to the

HART Communicator's serial port, 4-20

mA signal line, or NiCad recharger jack in

an explosive atmosphere.

1. At a convenient point, break the analog

output 4-20 mA signal line and install the

optional 250 ohm load resistor.

2. Plug the load resistor into the loop connectors

(located on the rear panel of the HART

Communicator).

7-3. HART COMMUNICATOR PC CONNEC-

TIONS.

There is an option to interface the HART

Communicator with a personal computer. Load the

designated AMS software into the PC. Then link the

HART Communicator to the PC using the interface PC

adapter that connects to the serial port (on the commu-

nicator rear panel).

Refer to the proper HART Communicator

documentation in regard to the PC interface option.
