DESCRIPTION
RX-MFS-ESCAN-HS1A is an 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-HS1A 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
