RS232 Pin Assignment

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.

RS232 Pin Assignments
Pins Signal Description Data Direction
2 RXD Receive Data Into AccuPyc
3 TXD Transmit Data From AccuPyc
4 DTR Data Terminal Ready From AccuPyc
5 GND Ground N/A
6 DSR Data Set Ready Into AccuPyc

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.
