CP7317RS FEATURES
4.1
RS-232 PORT
This port (located next to the power outlet) is a fully
programmable, bi-directional, and full duplex port
that has the ability to operate at any baud rate up
to 9600. The general standard on transmission is 8
bits, no parity, and 1 stop bit. The factory default
for communication through this port is 2400 baud.
Several standard baud-rates are available through
programming: 300, 600, 1200, 2400, 4800, and
9600 baud. The following table shows the pin-out
configuration of RS-232 ports on the CP7317RS.

RELAY CONTACTS
The CP7317RS has 4 ports with relay contacts.
Port 1 has two groups of 4 relays. The relays are
single-pole, single-throw (SPST) type and can be
set to default to either a normally open or normally
closed condition. Each relay of port 1 can be
individually turned “ON” or “OFF”. Figure 1 shows
port 1 configuration.

Subsequently, Port 2,3, and 4 can be treated as a
single port with 8 relays or as three independent
ports. Port 2 can be treated as a single port with 4
relays and Port 3 and 4 with 2 relays each.

In addition to relay contacts the CP7317RS
Controller has “+5” voltage available on ports 3 and
“GND”(ground) available on port 4. The
(+5) volts output is designed to drive external
circuitry and has 280mA maximum current output.
The graph below shows the maximum of allowable
current from +5V pin and through digital I/O pins as
a function of the number of relays turned ON at any
given time.

The ground pin on Port 4 is true ground and is
connected to the system ground but it is not
connected to any common pins.

DIGITAL I/O PORTS
These ports are designed as general-purpose
input/output ports (see Figure 4).
