OBJECTIVE or GOAL
Connect a benchtop lab instrument, such as a balance or pH meter, to Waters Serial Device Support (SDS) software. SDS makes the instrument available for use in LMS Smart Builder forms.
- NuGenesis 8 LMS
- Waters Serial Device Support (SDS) 2.0 or higher
- One Tibbo Device Server has been purchased for each lab instrument to be connected to SDS
The following is a quick checklist for connecting a lab instrument to SDS. It is intended as a quick-reference guide for people who are already familiar with SDS. For those unfamiliar with SDS, please see the attached document.
- Get the make and model numbers of all instruments that are to be connected via SDS.
- Obtain the manuals for each model of instrument. Electronic manuals are preferred so that they can be easily sent to support for assistance.
- Read the manual to determine a model's RS232 port's physical properties and its serial communication capabilities. Look for terms "RS232" or "serial port" in the e-manual, or look for information in the admin/setup/configuration chapters, or perhaps a technical specs/reference chapter.
- Obtain the necessary cables. Often it's a standard 9-port serial cable, but it might be a 25-pin port on the device, or a non-standard port, which would require a converter or a manufacturer-specific cable. Rarely is it a null-modem cable, which is visually similar to a standard cable but does not have the wires reversed; the need for such a cable is usually highlighted in the device manual.
- Connect the device to a Tibbo box. Connect the Tibbo box to power and to Ethernet.
- Use the Tibbo Device Server Toolkit software on a PC to find the Tibbo box. The PC must be on the same network segment as the Tibbo box; ideally, it should be plugged into a port next to the Ethernet port used by Tibbo. WiFi is not recommended because wireless tends to be on a different network segment than the wired ports.
- Configure the Tibbo box with a static IP address as provided by IT. Restart the Tibbo box through the Tibbo DS Manager software.
- Configure the Tibbo box's RS232 parameters per the device manual.
- Verify that the device's RS232 parameters are as specified in the manual. Use the device's physical interface to check the parameters (baud rate, parity, # of bits, etc.), and if they differ from the manual, configure Tibbo to match the device's settings.
- Use the SDS Diagnostics program to verify connectivity with the device. Use a PC with a physical serial port for this purpose; USB-to-serial converters are not recommended. Examine the device's output. Save a copy of it's output to a text file.
- Use the SDS Configurator program to build a configuration file for the device. Enter it's IP address and port. If it accepts commands via RS232, select Active mode; if not, use Passive mode. Configure regular expressions to extract each relevant bit of data from the device's output.
- Upload the SDC file to the device's record in the LMS Instrument Inventory.
