CONNECTION
The RS232 Interface Kit cable terminates with a 9 pin Sub-D female connector.
Active pins: Pin 2 = TXD, Pin 3 = RXD, Pin 5 = Ground, Pins 4 and 6 are connected for hardware
handshake, Pin 7 = CTS, Pin 8 = RTS.
The Interface connector will connect directly to a computer, an Ohaus printer and many other printers.
OPERATION
RS232 OUTPUT
With the Adapter installed the balance will operate in one of the following three ways:
•
RS232 = on, Auto Print = off, Stable = on or off
Pressing PRINT will send the display data.
If Stable is set to On, the balance will wait for a stable reading before sending data.
•
RS232 = on, Auto Print = on, Stable = on or off
The balance will automatically send data based on the settings in the Menu.
If Stable is set to On, only stable values will be sent.
•
RS232 = off
The interface is turned off. During battery operation, this saves significant power.
Data sent from the Interface is in standard ASCII format terminated with a [CRLF] (carriage return-
line feed). The output format is as follows:
[weight]
10 characters (right justified)
[space] 1
character
[unit]
5 characters max (left justified)
[space] 1

[stability indicator]
1 character
“?” when unstable, blank when stable
[space] 1

[legend]
10 character
TOTAL, hh:mm:ss(time interval), etc.
[CR] 1
