Setting Up the Serial Port for Communications With
Other Devices
Before serial communication can be initiated between the ELx800™ and another device
(such as a host PC running BioTek’s Gen5™, KCjunior™ or KC4™ software), the
communication parameters must match between the devices.
The ELx800 has a 25-pin serial (RS-232) port located on the rear panel of the
instrument. The serial port allows the reader to communicate with a computer, using
standard communications software and/or RS-232 protocols.
Appendix A contains
information on required protocols for computer control of the reader.
The serial port also allows field upgrades of the ELx800 software.
Attaching the Cable
1. Power down the computer and the ELx800.
2. Connect the appropriate serial cable to both machines. The serial port on
the reader is a DTE configuration with a 25-pin (pin-male) D-sub connector.
3. Power up the reader and the computer.
4. Ensure that the ELx800 and the computer are operating with the same
communications settings.
Installing Software on the Host PC
Refer to the Gen5 Getting Started Guide or Help system, or to the KC4 or KCjunior
User’s Guides for complete instructions for installation of the software. Refer also
to
Appendix A for basic software installation and configuration instructions.
Setting Communication Parameters
The reader’s default communication parameters are:
• 9600 Baud Rate
• 8 Data Bits
• 2 Stop Bits
• No Parity
The baud rate can be changed to 1200 or 2400 bps, if necessary.
The Data Bits, Stop Bits, and Parity settings cannot be changed.
