The following information applies to the : CAL3K-AP , CAL3K-A,CAL3K-F.
The CAL3K has four communication ports for connecting to the outside. These ports are:
|USB 2.0||Prime access port, short distance, no restrictions|
|DATA#1||RS232, 1.2 - 115.2Kb, 10-30 meter distance|
|DATA#2||RS232, 115.2Kb, 10-30 meter distance|
|(BALANCE RS232, 1200 – 38400 baud, 10-30 meter distance)|
The operations of the RS232 ports #1 and #2 can be restricted via the USB port.
In addition the PORT D1 can be assigned to printing or LIMS output only.
The DATA# 1, 2 ports are meant to be connected to REMOTE devices. The restrictions apply to the ‘operational powers’ of these ports. A good example is the ability to RESET the CAL3K: If the unit is reset from a remote device during the main period then the determination is aborted and the result is lost.
Here is a list of possible port restrictions:
- Delete Results Enable
- Clear Event Log Enable
- Perform a temperature calibration enable
- Load default parameters enable
- Load Vessel default parameter enable
- Load default ID parameters enable
- Reset enable
The list may change with time. Note that there are no restrictions to uploading data, or any form of data retrieval!
The three ports are functional the same, apart from the restrictions. This implies that the port#1 and port#2 restrictions must be changed from the USB port.
The location of the ports depend on your calorimeter type. The ports are clearly labeled.
If you’re PC for data handling (LIMS) has no RS232 connector then the Wire Replacing adapter set is recommended.
All ports are bi-directional and respond to requests issued by the remote device. If a port is supporting LIMS operations, then the port is OUTPUT only and data are send to the ports ‘unsolicited’ when they become available. For details see: PC Enabling LIMS Support.
CONNECT A PC TO THE CAL3K
The CAL3K has three ports to connect a PC or laptop to. These ports are: USB. Distance approx. 2 meters. Ideally suitable for laptops. A USB cable is supplied in the 3K-1-KT (USBCABAB), RS232 DATA D1 Port. Distance approx. 20-50 meters. Speed: 1.2 - 115.2Kb, RS232 DATA D2 Port. BLUETOOTH. Speed 115.2Kb.Learn More
The LIMS (Laboratory Information Management System) output must be enabled on the D1 port via the PORT DEFINITION. The data port D1 has the following specification: RS232, 8 bit, no parity, 1.2 to 115.2Kb. The following items must be set to affect a LIMS output...Learn More
All CAL3K units have the same connectivity as the other family members. The family members are : CAL3K-AP, CAL3K-A, CAL3K-F. 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
