The ControllerThe Concept As a producer of hardware we know that it is expensive to make custom equipment.The vision of the controller is to have a single versatile hardware interface that can be made into virtually any custom instrument by means of softwareThe Infinity concept is to create custom instruments in software, similar to LabView, but with two significant advantagesBetter Hardware- Ultra-high resolution inputs, serial and digital interface components needed for laboratory and process controlBetter Software – Written in VB.net and designed specifically for your application. Using dot.net language removes many programing limitations and J-Kem also releases the original source codeTechnical SpecificationsThe standard Infinity controller has analog inputs for two type T thermocouples, 1 pH probe, and one pressure input. Additionally, one of the serial ports on the side of the controller is programmed to operate an overhead stirrer, a second port is configured for a chiller, and a third port is available for an additional instrument.Analog inputs – If you wish to use the thermocouple and pH probe inputs, then attach the sensors to the appropriate connectors. To monitor the pressure of an attached reactor, connect a piece of tubing from the pressure transducer input on the back of the controller to the reactor to monitor.Serial Inputs – Connect a 9-pin serial cable between the port on the side of the controller labeled "Stirrer" to the serial port on the stirrer. Connect a second serial cable between the port on the side of the controller labeled "Chiller" to the serial port of the chiller. NOTE – prior to ordering, the model number of the chiller and stirrer must be specified (this is for FAT).

Pump ControllerController The pump is operated from your PC and is the most versatile syringe pump available. Programs are stored and recalled, and the experiment's progress is displayed on the PC. PUMP CONTROL SOFTWARE IS SUPPLIED WITH PUMPStandard ProgramsComes with KEM-Pump graphical control software that runs the syringe pump module.   KEM-Pump implements all of the standard programs of the SYR-1200 plus additional programs for serial and multi-reactor reagent additions. Unlike any other syringe pump, KEM-Pump is an open source code application that allows researchers with programming experience to create their own applications without limitations.Pre-written applications include:Timed Addition  -Adds a single reagent (any volume) to a single reactor at a user specified rateMulti-Step Timed Addition  -Adds up to 16 different reagents, independent volumes and rates to a single reactorMulti-Reactor Addition - Adds a single reagent to 1-7 different reactors at independent rates and volumesProgram Builder  -A drag-n-drop application, for non-programmers, to build sophisticated pump programs

Serial Communication IssuesSerial communication with external instruments is a very complex task, primarily because there are somany different manufactures and each manufacture uses its own unique communication protocol andcommand set (additionally, some manufactures do a very poor job implementing reliable serialcommunications). J-KEM has simplified this complex task by pre-configuring the Infinity controller withthe communication parameters of the most common laboratory instruments. Three elements must beaddressed to successfully communicate with an instrument through the Infinity software.1) The instrument must be connected to the proper Infinity (or PC) port.2) The instrument must be programmed with the correct communication parameters (like the correct baud rate). In general, the only parameter that must be set in the instrument is the baud rate. The baud rate should be set to 9600. In any case, the baud rate set in the instrument (chiller, stirrer, etc.) must be the same value specified in the Serial Port Configuration table. Contact the instrument manufacture for assistance.3) The correct cable must be used to connect the instrument to the Infinity controller. This is veryimportant, and is usually the source of errors. Below is a list of instruments that use non-standardcables. If you do not have the correct cable, it must be purchased.

Instrument Specific IssuesThe serial communication protocol for every manufactures instrument is different, additionally, some instruments have special cable requirements. To the degree possible, know issues with common instruments are listed below.IKA Stirrers IKA stirrers must be connected directly to the PC, either a PC 9-pin serial port or a USB port.IKA manufactures a wide verity of stirrers, but most fall into these categories. Stirrers with 15-pin serial connectors – These stirrers require a custom USB to serial cable. This cable is available CG-1978-Q. Stirrers with 9-pin serial and USB connectors – To use the 9-Pin connector, you must use the proper USB to serial cable CG-1978-Q to use the USB connector, you must install the VCP driver available from IKA.Julabo Chillers These chillers require a custom 9-pin serial cable. These are available CG-1978-Q cables.Huber Chillers These chillers require a custom 9-pin serial cable. These are available CG-1978-Q cables.Heidolph RZR StirrersThese stirrers require a custom 15-pin serial cable. These are available CG-1978-Q cables.Serial commands for four RZR models are implemented, the models 2051, 2052, 2102, and 2012Z. Each of these stirrers have different speed ranges. It is the user’s responsibility to not send a speed outside of the stirrer’s range. In the case of the Model 2102 stirrers, the user must manually place the stirrer in Speed range I or II using the stirrers front panel controls before starting a run with the Infinity controller.DON’T FORGET YOUR HUBER REQUIRES AN E-Grade or DV-Grade Up Grade
