The units have three general communications ports : A USB port and two RS232 ports. All ports can have the same functionality. However, the USB port can restrict and assign the RS232 port's functionality. The USB port is the "master" and is used to set up other ports and configure the machine.
The RS232 port "D1" can be used for LIMS (Laboratory Information Management Systems) or printing. In addition to the three universal ports the CAL3K has a balance port.
MULTIPLE COMMUNICATION CHANNELS
All units have Multiple Communication Channels. USB (short distance for setting up and management). RS232 D1 port, variable baud speed, can be used for LIMS and printing, or wireless, or PC. RS232 D2 port, 115.2Kb, can be used for wireless, or PCLearn More
This overwhelming area of ports is required to connect to the real world. The USB port has unrestricted access (with password!) to the CAL3K and it can restrict the other RS232 ports functionality. The two RS232 ports are functionally the same. Both can be used with the PC software if your PC has a RS232 port. Most PCs don't have RS232 ports and for this reason both ports can connect to a BLUETOOTH bridge which requires a USB (virtual) port on the PC.Learn More
CONNECT A PC TO THE CAL3K
The two RS232 ports are functional the same, just the name changes. This means you can connect a BLUETOOTH device to either RS232 port. Connecting a BLUETOOTH or other wireless device to the USB port is not recommended. All three ports have the same functionality. That is to say that the supplied CAL3K software can operate on any of these ports.Learn More
