Configuration
n This letter designates the status of the pin
as either high or low during “Power up” of
the unit.
when n = 1 the pin is set as high
when n = 0 the pin is set as low
Example: Set pin 1 of port 3 as low during
POWER ON. [SETPD3,1,0]

This command sets the “Power ON” status of all
the pins on the particular port of the unit. This
command determines whether port pins will be high
or low during “Power up”. It is a programming
command and should be issued only once during
the configuration of the CP7317RS. Once issued,
this command is stored in the non-volatile memory
and is maintained during Power “ON/OFF”.
The factory preset of the CP7317RS is that all pins
in all ports are set as output pins.
If it is required that the pin is set to low during
power up. The pin status must be set as output. If a
particular pin is set as the input then it can not be
set low by this command during “Power up”.
p This letter designates the port number. It is
an ASCII character from 1 to 4 that
matches the port number on the back of the
CP7317RS. The acceptable values are 1, 2,
3 or 4. Any other value will cause an error
as a feedback code.
b This letter designates the pin numbe r. The
position of this number corresponds to the
number on the 9 pin connector on the back
of the CP7317RS. For example, b
4
is the
fourth pin on the connector. A valid range
for b is 1 or 0. Any other numbers will cause
an error as a feedback code.
Example: Set pins 1 through 3 on port 2 as
high; set pins 4, 6, 7 and 8 as low and pin 9
as high. [SETPD2,10101001]
[SETPRp,b,n]
This command sets the “Power ON” status of each
relay on a particular port of the unit. This command
determines whether a relay will be open or closed
during “Power up”. This command is a
programming command and should be issued only
once during the configuration of the CP7317RS.
Once issued, this command is stored in the non-
volatile memory and is maintained during “Power
ON/OFF”.
The factory preset of the CP7317RS is that all
relays are set to open.
p This letter represents the port number. This
is an ASCII character from 1 to 4 that
matches the port number on the back of the
CP7317RS. The acceptable values are 1, 2,
3 or 4. Any other value will cause an error
as a feedback code.
b This letter represents the relay number.
This number corresponds to the number on
the terminal block connector of the
CP7317RS as shown on the diagram
below. A valid range of numbers is from 1 to
8, inclusive. Any other numbers will cause
an error as a feedback code.
