1. DESCRIPTION RX-MFS-ESCAN-HS1 is a MFS 2.4GHz receiver with 2 CAN Interfaces, 2 independent E-Stop Relay Outputs, 2 Application Relay Outputs, 4 optional 0~10V, 0~20mA analog or 0~30V digital inputs, a USB and an optional RS232 interface. It shall be equipped with RTC and SD card for data logging capability. It is designed for applications using CAN bus topology to integrate a number of devices and operating on 12 or 24V battery. The function of this device is to provide a bidirectional RF control to CAN bridge in a machine control application, along with standard Main Contact safety functionality. Receiver and CAN settings shall be H-Link configurable and are saved to an on-board EEPROM. RX-MFS-ESCAN-HS1 uses the MFS 2.4GHz communication protocol. The decoder receives control packets at a 1%-10% duty cycle to the receiver and transmits one feedback packet for every control packet. The feedback packets are sent on one of the sixteen IEEE 802.15.4 ISM-band channels, ranging from 2.405-2.480GHz. The channels and duty cycle are configured with the H-Link software. The packets are DSSS O-QPSK modulated using an on-board surface-mount transceiver and then amplified through an on-board surface-mount bi-directional RF Front End. The RF signal goes through a surface-mounted SMA connector, through a 50-ohm coaxial cable to an external antenna for transmission/reception. The external antenna is a Hetronic Gainflex 2.4GHz antenna (Hetronic Part Number 56506605) with a nominal gain of 3dB.  The antenna is Model: 56506605 – Manufacturer: APEX - Gainflex Type GK 442TF R Half wave flexible dipole – maximum power 10W – TNC Plug Reverse Polarity  Antenna Gain: 3 dB Note: Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Note: The RX-MFS-ESCAN-HS1 is shipped with the FCC/IC ID label attached. The FCC/IC ID label must not be removed. See Figure 3 for additional labeling information. FCC ID Number: LW9-RXMFSCANHS1 IC ID Number: 2119B-RXMFSCANHS1
RSS-Gen license-exempt notice: “This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.” RSS-Gen antenna notice 1: “Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. ”

FUNCTIONAL DESCRIPTION 3.1. Operation As a standard Hetronic MFS receiver, this module is equipped with 2 microcontrollers, Main and Stop, for safety and redundant control of E-Stop Relay outputs. The Stop controller is common to standard 2.4GHz MFS receivers. The Main controller will have full control of RF, analog inputs, digital outputs, USB, RS232 and CAN interfaces. There are 2 CAN interfaces, namely CAN1 and CAN2, with optional isolated supplies, RS232 interface with a 4-pin Dubox header and a USB interface that can be used for firmware update and H-Link configurations. CAN2 will be dedicated to J1939 protocol for possibility of controlling and monitoring other devices on the truck using J1939 protocol. CAN1 will be used as a CAN Master on CAN open protocol to control and monitor other Hetronic Slave devices. RTC with a back-up battery shall be used to keep time for data logging of different possible events such as abnormal conditions and operating times. Nominal operating voltage range will be 9 to 24Vdc. Electronic control unit will remain operational within 6 to 36Vdc. 3.2. Operation
