14 COMMUNICATIONS AND OUTPUTS
Communication with Series 7 force gauges is achieved through the micro USB or 15-pin serial ports
located at the bottom of the instrument, as shown in the illustration in the Power section. Communication
is possible only when the gauge is in the main operating screen (i.e. not in a menu or configuration area).
14.1 Serial / USB
To set up RS-232 and USB communication, select Serial/USB Settings from the menu. The screen
appears as follows:
Select either RS-232 or USB input (output is always active for both the USB and RS-232 ports). RS-232
must be selected when communicating through a Mark-10 test stand controller. When communicating
from the gauge directly to a PC or data collector, either RS-232 or USB can be selected as required.
Press DATA to transmit individual data points or to commence an automatic output sequence (see
Automatic Output sub-section for details). Single point or continuous data may also be requested via
ASCII commands from an external device (see Command Set sub-section for details).
Communication settings are permanently set to the following:
Data Bits: 8
Stop Bits: 1
Parity: None
Other settings are configured as follows:
14.1.1 Baud Rate
Select the baud rate as required for the application. It must be set to the same value as the receiving
device. When communicating with a Mark-10 test stand controller, the baud rate must be set to 9,600.
14.1.2 Data Format
Select the desired data format. The screen appears as follows:
