GENERAL DESCRIPTION The 7I47S is a 12 input, 8 output RS-422 interfface for Mesa’s Anything I/O series of FPGA interface cards. The 7I47 has 12 receive and 8 transmit channels plus a analog output intended for spindle speed control. The 7I47S is mainly intended for motion oriented applications, for example as an output buffer and line receiver for connecting step and direction drives and encoders to Anything I/O FPGA cards. -
Page 5: Hardware Configuration
CABLE POWER ENABLE The 7I47S can supply I/O power to P3 and P4 via P1 or via the 50 conductor flat cable. If W1 is in the left hand position, flat cable power is used. If W1 is on the right hand position, P1 power is used. -

Page 7: Controller Connector
50 pin header connector J1 connects to the anything I/O card/motion controller. This can be a male 50 pin header on the top of the 7I47S card or a female 50 conductor header on the bottom side of the 7I47S depending on 7I47S model. - Page 8 CONNECTORS RS-422 CONNECTOR P4 Connector P4 is a 3.5MM pluggable screw terminal block with the following pinout: P4 PIN FUNCTION TO 7I47S /RX0 TO 7I47S FROM 7I47S TO 7I47S /RX1 TO 7I47S FROM 7I47S TO 7I47S /RX2 TO 7I47S TO 7I47S...

Page 11: Operation
The power from connector P1 Passes through a 1.3A PTC device before being routed to the I/O terminals. This limits the total I/O power supplied by the 7I47S to ~800 mA in 0 to 70C ambients. RS-422 OUTPUT DRIVE The 7I47Ss outputs are designed to drive singly terminated RS-422 lines or remote opto-isolator diodes. -
Page 12: Analog Out
OPERATION ANALOG OUT The 7I47S provides one analog output for spindle control. The analog output is a isolated potentiometer replacement type device. It functions like a potentiometer with ANALOG + being one end of the potentiometer, ANALOG OUT being the wiper and ANALOG- being the other end. -
