Digital Inputs 

There are 4 digital inputs available on the Model 9840.  They are accessible on the Digital 
I/O connector on the back panel (pins 9 - 16).  These inputs are individually opto-isolated 
and include current limiting resistors.  An input voltage anywhere from +4 to +22 volts DC 
may be used to obtain the “on” state.  See Appendix B for a full description of the Digital 
I/O connector. 

If you do not require isolation for your application you can use the +5 or +12 volt and GND 
available on the Digital I/O connector (pins 24-26).   

These 4 inputs are called IN1 through IN4 and have the following standard functions: 

Functions may be assigned to these inputs by custom programming at the factory. 
 
All the features and settings of the Model 9840 can be accessed remotely using the 
Remote ASCII command set.  These commands fall into three groups: those similar to 
the Run Mode touchscreen commands; similar to the Setup Mode touchscreen 
commands; and similar to the Calibration Mode touchscreen commands.   
 
Communications can be established via RS232 protocols through the serial port on the 
rear panel of the unit, or via USB communications through the USB port on the rear panel 
of the unit in conjunction with the USB driver installed on the host PC.  The commands 
and command formats are the same for each method of communications.   
 
Pinouts for the RS232 serial port communications are listed in Appendix B of this manual.  
For older computers, USB communication may require the installation of the USB driver 
located on the CD-ROM that accompanies this product.  If the host PC can communicate 
with the Model 9840 via USB, no driver is needed. 

USB Driver 

If the host PC cannot communicate with the Model 9840 via USB, install the USB driver 
that accompanies this product on CD-ROM.  To install the USB Driver, place the CD in 
your CD-ROM drive.  Select Run from your Windows Start menu.  Type 
D:\USB_Driver\CDM_Setup.exe (“D” or the corresponding CD-ROM drive letter for your 
computer) in the box and hit Enter. You will be notified when the driver has finished 
installing. 
 
If no CD-ROM was received, download and install the USB driver from 
http://www.ftdichip.com/Drivers/VCP.htm. You need to download and install driver version 
2.04.06 or higher.  Click on the download link 2.04.06 listed next to Windows XP and 
follow the download and install instructions. 

 
Communications Settings 

The Model 9840 supports remote operation using a standard Remote interface consisting 
of ASCII characters and terminal emulation software package such as HyperTerminal or 
ProComm.  The baud rate for the Model 9840 is in  “Com Baudrate” within the Systems 
Options of the Setup Menu.  Supported rates are 

300

, 

600

, 

1200

, 

2400

, 

4800

, 

9600

, 

19.2k, 38.4k, 57.6k, 

and 

230.4k

 baud.  There must be 

8 data

 bits, 

no parity

, and 

1 stop

 

bit. USB Communications does not require this setting to function.
