IN SSIGNMENT
The AccuPyc is a standard DTE device. The RS232 port can be used to connect an analytical
balance for transfer of sample weight, or for transmitting data to a computer. The receiving device
must be configured to interface with the RS232 pin assignments. Any signals that are not listed in the
RS232 Pin Assignment table are ignored.

The AccuPyc uses the DTR and DSR signals for hardware flow control. Ensure that the serial
device provides these signals. For example, if attaching to a computer (also a DTE device), use a
null modem cable which includes the designated signals. If transmission problems occur, ensure that
the signals are set up properly. If the signals are correctly configured, contact the receiving device
manufacturer for assistance.
