Remote Mode Operation

Remote mode operation is when the 4200-DR is being controlled by a computer

over the USB interface. When in remote mode, the 4200-DR behaves differently,

preventing you from affecting the operation of the instrument, such as changing

the set point, unless enabled in Comm menu. You cannot enter the menu

without taking the unit out of remote mode, and the knob is disabled.

You can exit remote mode at any time by pressing the Menu button, which has

a secondary function to return the 4200-DR to local operation.

While in remote mode, the Remote LED also acts as an activity indicator, and

will flash whenever there is communication with the computer.

Details on how to communicate with the 4200-DR can be found in the

Computer Interfacing Manual which is included on the CD that accompanied

this product.

Installing the USB Drivers

Using the 4200-DR via USB is just as simple as using the serial port. In fact,

once you have installed the USB drivers, the instrument will appear as a virtual

serial port that you can use just like a normal serial port.

To install the drivers, simply plug in the instrument to your computer. When the

Add New Hardware wizard appears, insert the CD you received with the 4200-

DR and follow the on-screen instructions.

Once the drivers are installed, to determine the COM port number, go to Control

Panel and select System. Once the System Properties dialog appears, choose

the Hardware tab then click on the Device Manager button. When the Device

Manager appears, click on the plus sign to the left of Ports. The port identified

as a USB Serial Port is the 4200-DR. In the event you have multiple Arroyo

Instruments products plugged in simultaneously, you will need to experiment to

see which instrument was assigned to which port. For example, you could send

a *IDN? query and see which instrument goes into remote mode.
