PAGE 31
Appendix II RS-232 Serial Data Communications The balance keyboard functions can be accessed via the RS-232 interface. The following commands are available: u = UNITS key m = MODE key % = % key t = tare function p = print function # = immediate print a = auto display response rate f = fast display response rate s = slow display response rate Receiving Data Using the Immediate Print Symbol When a balance is connected to a computer, it is suggested that immediate print (“#”) be used.
PAGE 32
The immediate print output is always transmitted with a carriage return and line feed. If the balance is set to a specific number of line feeds, these will be transmitted with a carriage return. The RS-232 Interface Hardware Although Setra balances can communicate with almost any RS-232 device, the built-in interface does not include the complete protocol. Only the transmit and receive lines of the standard interface are used. This should not present any interfacing problems in most applications.
