Printing to a Printer or ComputerPrinting with PK-Series balances simply means that the displayed LCD con-tents are sent out the 9-pin RS-232 port to either a connected printer orcomputer. To successfully print the following conditions must exist:1. Attach the balance to a printer or computer using the appropriate datainterface cable. The correct cable must be used to connect the twodevices together. Correctly configured cables can be purchased fromDenver Instrument, or, can be made by the user. See the table “DataInterface Cable PIN Configuration For PK-Series Balances”.2. The RS-232 settings on both the balance and printer (or computer) mustbe the same. Both devices must be set to the same number of data bits(“7”, not configurable), baud rate, parity, stop bits and handshake.3. If the balance is set to manual print (default), press and hold the“TARE/PRINT” key until an audible beep is heard. The LCD contents willbe sent out the RS-232 port to the attached device.Controlling The Balance Remotely Via ComputerBecause the PK-Series RS-232 interface is bi-directional, a connected com-puter can remotely control the balance. There are nine (9) balance func-tions, as listed in the table entitled “Remote Balance Operation Functions& Control Codes” that can be remotely invoked from an attached comput-er. The process of sending these codes varies depending on the computersoftware used. Programming languages such as C++ and Visual Basic canbe used to create routines to grab data from the balance. There are alsomany software packages commercially available to help users capture datafrom RS-232-enabled laboratory devices, like the PK-Series.11
