All documents are provided for download at www.knick.de. 3 FCC ComFu 300 Wireless Set (ComFu 300C, ComFu 300E) This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
1. 2. This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. ComFu 300C Note:
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a resi-
dential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. 4 Radio Transmission with ComFu
"ComFu" is a ZigBee wireless set for wireless data transmission between sensors and the measuring system. "ComFu" consists of the ComFu E end device on the sensor (up to 2 units) and the ComFu C wireless coordinator on the analyzer. E 0 0 3 u F m o C l 1 e u d o m

The "ComFu" ZigBee wireless set has a 400 m range in free field. The ZigBee "Coordinator" automatically searches for free channels. The data is securely encrypted using AES 128 bit key and is transmitted with CRC tele-
gram protection. The ZigBee modules on the sensors communicate interval-controlled. Therefore they always operate for a short time only. One battery set allows an operating time > 1 year (depending on measuring rate and outer temper-
ature). The "ComFu" ZigBee wireless set uses the 2.4 GHz frequency band. Here, 16 channels with a maximum data rate of 250 kbits/sec are available:
Channels 11 ... 26
(16 channels) 2.4 GHz 5 MHz 2.4835 GHz 5 ComFu 300 E Sensor End Device The ComFu 300 E (end device) is a radio sensing element with automatic sensor recognition. Measured values and sensor data are transmitted to the ComFu 300 C wireless coordinator by radio, which is connected to the Protos 3400 measuring system. ComFu 300 E is configured through the Protos 3400 measuring system. The rotary switch on the ComFu 300 E allows setting the operating modes ON, OFF, or HOLD. Measured values and status messages are transmitted cyclically, the transmission interval for the measured values can be freely configured. The rotary switch allows setting the operating modes ON, OFF, or HOLD flashes green every second Red and green LEDs signal the operating mode, battery replacement, and pre-alarm Connecting to network Normal measuring mode flashes green every 4 seconds HOLD No connection Battery replacement required Battery replacement Turn the lower cap nut clockwise until the battery chamber can be pulled out of the stainless steel housing. Be sure to observe the correct polarity when inserting the 8 AA batteries (see markings in the battery chamber). flashes red every 4 seconds lights up red (for 3 seconds) flashes 2x red every 4 seconds Measuring module for connecting a sensor Measuring modules for pH and ORP are available. The measuring module looks like a cartridge. It is simply shifted into the ComFu 300 E and secured with the coupling nut. 6 ComFu 300 E: Connection ComFu 300 E is designed for operation with pH sensors with integrated temperature detector and VP cap. For connecting the sensor, Knick provides special cables with VP connectors on both cable ends. These cables are available in two versions for sensors with and without solution ground. With the suitable cable type, correct connection of the sensor is automatically ensured. Wiring example:

It is operated and configured from the Protos measuring system see instruction manual for FIU 3400-141 module on included CD-ROM
(or in the download area of our website www.knick.de). ComFu 300 C establishes and controls a radio network. It can communicate bidirectionally with up to two ComFu 300 E units. The ComFu 300 C receives its power from the FIU 3400-141 module. Failure or disruption of the data transmission is immediately recognized by the ComFu 300 C and signaled to the Protos measuring system. ComFu 300 C can be installed in an optimal position. The Protos 3400 measuring system with display and keypad should be installed at a location which is easy to access for the operator. The antenna should be positioned so that a line of sight between the ComFu 300 E end device and the ComFu 300 C wire-
less co ordinator is maintained. Obstacles in this line reduce the maximum range or even make wireless data communication impossible. A "Network Planning" document is available on request. RS-485 connection for communication with control unit. For connecting the RS-485 cable, please refer to the instruction manual of the Protos 3400 FIU 3400-141 module on the included CD-ROM (or to www.knick.de). 8 Configuring the FIU 3400-141 Module Specifying the "Radio" mode Note: HOLD mode active.
