SUPPLIED CONFIGURATIONS
7I77_7I74D
7I74_7I77D is a configuration intended to work with a7I77 six axis analog servo
daughtercard on P2 and a 7I74 eight channel RS-422 interface daughtercard on P1. It
includes six encoder inputs, 14 smart serial interfaces (2 used on the 7I77 for 48 bit
isolated field I/O and analog out) , a watchdog timer and GPIO.
7I74X2D
7I74X2D is a configuration intended to work with two 7I74 RS-422 daughter cards
It include sixteen smart serial interfaces allowing real time control of up to 784 digital I/O
points, a watchdog timer and GPIO.
7I78X2D
7I78X2D is a configuration intended to work with the 7I78 four axis step/dir
daughtercard. It will support two 7I78 daughtercards, one on each of the 7I92s I/O
connectors. The configuration includes eight hardware step generators, two PWM
generators, two encoder inputs and two Smart Serial interfaces, a watchdog timer and
GPIO
PROB_RFX2D
The PROB_RFX2D configuration is a step/dir configuration intended to work with
most common parallel port breakouts. Two breakouts are supported, one on each of the
7I92s I/O connectors. The configuration includes eight hardware step generators, two
encoders with index, four PWM generators , a watchdog timer and GPIO.
PIN FILES
Each of the configurations has an associated file with file name extension .pin that
describes the FPGA functions included in the configuration and the I/O pinout. These are
plain text files that can be printed or viewed with any text editor.
