Instruction Manual – FA Series Force Gauge
12.4 Interface and USB Port Configuration
The Interface menu is designed to allow you to change the format and rates at which information is transmitted
to a computer. You must connect the force gauge to the computer using the USB port. To access this function
go to CONFIGURATION in the Main Menu.
* To connect the force gauge up to a computer it is recommended that TORBAL FM is installed on the
computer. With this program the user can view real-time results and measurements from the force
gauge. TORBAL FM also allows the user to fully control the force gauge from the computer. The
TORBAL FM settings must match those of the force gauge.
The optimal settings from transmitting information to a
computer are as follows:
-Baudrate (transmission and receiving rate): 4,800, 9,600,
19,200, 38,400, 57,600, 115,200 bps.
-Bits (the number of bits which define a character): 7 or 8
bits.
-Parity (refers to the alteration of the process that the bits are sent and received in): none, odd, even.
-Sending (the transmission method during measurement):
Normal
Waits for stable results after pressing PRINT before sending.
NO STB Sends results regardless of stable results after pressing PRINT.
AUTO STB Automatically sends after the result has stabilized.
CONTIN. Sends continuous transmissions (approx. every 0.1s).
Description of the data transmission protocol when working with a computer (LonG):
The scales transmit the result as follows (8 bits, 1 stop, no parity, 4,800 bps):
Computer

Gauge: initiating signal S I CR LF (53 h 49 h 0Dh 0 Ah),
Gauge

Computer: gauge indication according to the following format (16 bytes)
Description of individual bytes:
byte 1 - “-“ or space
byte 2 - space
byte 3-4 - digit or space
byte 5-9 - digit, comma or space
byte 10 - digit
byte 11 - space
byte 12 - k, l, c, p or space
byte 13 - g, b, t, c or %
byte 14 - space
byte 15 - CR
byte 16 - LF
