Mounting

For best performance of RHSS-12 below points needs to be taken into consideration. 1) The hole in the panel should not be more than 9.5mm. 2) RHSS-12 should be mounted with Star washer given along with the product and perpendicularity

Magnetic Cross Talk

If two RHSS-12 units are to be installed closer than 2 inch (measured between the center of both shafts), a magnetic shield, such as a small steel plate should be installed in between to prevent one encoder from causing small changes in reported position through magnetic field cross -talk.

Two Wire Communication

The RSSK12-XI2C is a Absolute encoder which acts as a slave and communicate with master micro controller as per the standard Protocol of I2C. It is also known as Two Wire Communication.

RSSK12-XI2C communicate in 8 Bit of Transmission. RSSK12-XI2C has a provision of Dual Output first I2C communication and PWM mode of communication 14 Bit and 12 Bit of Resolution respectively.

As per standard Protocol each slave (RSSK12-XI2C) has a Slave address of 7 bit which is being made of two Address Pin 1 and 2 while the remaining 4 bits are always 0 and MSB being 1. Address pin 1 and 2 are Least significant bit of Address. Hence we can use maximum of 4 such sensors in a Daisy chain mode of communication with slave address as 1000001 / 1000000 / 1000011 / 1000010.

RSSK12-XI2C communicates the angle information in two cycles. By sending the register address 254 and 255. To have the complete angle information we need to eliminate two most significant bit (6 and 7) of the data byte we receive after sending register address 255.

RSSK12-XI2C will communicate the angle information in below pattern

Serial Peripheral Interface

The RHSS12-XSPI is a Absolute encoder which acts as a slave and communicate with master micro controller as per the standard Protocol of SPI.

As per standard protocol of SPI RHSS12-XSPI communicate with master protocol when the MOSI pin is active high or 3FFF hex data is sent on the bus and the CS pin need to toggle from low to high for only one clock pulse.

RHSS12-XSPI communicate in 16 Bit of Transmission. After each cycle of communication it is compulsory to toggle CS pin from high to low.

RHSS-XSPI has a provision of Dual Output first SPI communication and PWM mode of communication 14 Bit and 12 Bit of Resolution respectively.

Number of sensors can be connected in daisy chain mode of 4 wire or (n+3 wire connection). please contact Mr. Pavan Kinariwala (pavankinariwala@gmail.com) for more information on the same. RHSS12-XSPI will communicate the angle information in below pattern.
