7I47S 1
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
outputintendedforspindlespeedcontrol.The7I47Sismainlyintendedformotionoriented
applications, for example as an output buffer and line receiver for connecting step and
direction drives and encoders to Anything I/O FPGA cards.
The controller connection is a 50 pin header that matches the pinout of Mesa’s
Anything I/O cards. All RS-422 interface connections use pluggable Phoenix compatible
3.5 mm screw terminals.

HARDWARE CONFIGURATION
GENERAL
Hardware setup jumper positions assume that the 7I47S card is oriented in an
upright position, that is, with the 50 pin controller connector is on the left hand side.
DEFAULT CONFIGURATION
JUMPER FUNCTION DEFAULT SETTING
W1 CABLE/AUX 5V POWER LEFT = CABLE POWER
W4 RX11 LEFT = TERM
W5 RX5 LEFT = TERM
W6 RX10 LEFT = TERM
W7 RX4 LEFT = TERM
W8 RX9 LEFT = TERM
W9 RX3 LEFT = TERM
W10 RX8 LEFT = TERM
W11 RX2 LEFT = TERM
W12 RX7 LEFT = TERM
W13 RX1 LEFT = TERM
W14 RX6 LEFT = TERM
W15 RX0 LEFT = TERM
TERMINATION ENABLE
The 7I47S can terminate its RS-422 inputs if desired. Termination is enabled by
setting the appropriate jumper to the left hand position. If termination is not desired, the
jumper should b moved to the right hand position.
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.

AUX 5V POWER
2 pin pluggable terminal P1 can be used to supply 5V power to the I/O terminals on
the7I47S. This is suggested for most applications as the encoders typically will drawmore
current than can be supplied via the FPGA flat cable. P1 has the following pinout:
