to reach all devices. It is designed to handle multiple IR codes so that only one
sprayer is needed for many devices.
NOTE:
The C2I-IR1 port does not support simultaneous IR and RS-232
control. That is, an IR driver cannot be stacked on the port together with a one-
way serial driver. The control format must be of one type. Use only one 1-way
Serial Driver or up to five IR drivers.
In addition, the IR port does not have negative voltage and thus may not provide
the full voltage range required by some RS-232 devices (although nearly all RS-
232 devices will operate properly). In these cases the DB9 serial COM ports can
be used instead.
Slot 2: C2I-DI04
Slot 2 provides four digital input ports: <
o1
> through <
o4

Signals
•
Digitals: <o1> through <o4>
Description
The C2I-DIO4 provides four digital inputs for connection of external sensors or
other contact closure devices. The <
o
> outputs are a logical high until it detects
the presence of a low on the corresponding input.
The built-in port supports dry contact closure to ground.
Slot 3: C2I-COM2-232 - Port A and Port B
The C2I-COM2-232 provides two COM ports (A and B) for controlling serial
devices over RS-232.
NOTE:
Does not support RS-422 or RS-485.
Each COM port has a built-in two-way serial driver.
To program a serial driver or serial device expand the C2I-COM-2 in
