External I/O (D-Sub25 pin)
Input signal
(Control of the printer)
Output signal
(Check the printer status)
Synchronize
USB or Ethernet (Used to transmit commands)
External device
Overview
This guide describes the external I/O specifications for the CW-C6000 Series/CW-C6500 Series. Please develop
your device to match these specifications.
Functionality
Using the external I/O signal allows the user to perform synchronous control of the printer and external devices
and to check the printer status.
Signal transmission between the printer and external device uses a D-Sub 25 cable.
Also, use a USB cable or Ethernet cable to send commands, which set the operation for the external I/O, from
the host PC.
System structure
1
A system using the external I/O can be structured as follows.
9
External device
The following external devices can be connected.
• Automatic application machine
• Roll rewinder
• Devices that must sync with the printer other than the above
The number of possible connections is one.
Q NOTE
10
External I/O Specification
This section describes the external I/O for the printer.
Connector
The external I/O connectors are as follows.
D-sub25 connector (female connector)
Screws: Metric screws
13 1
25 14
Chapter 2 External I/O Specification
Be sure to use the screws to affix the connection cable and ensure the cable does not fall out.
Q NOTE
Signal Definitions
Pulse signal
A pulse signal is a square wave with a fixed short-term width. A low active pulse is a signal that changes sharply
from High to Low, maintains a low state for a short period of time, and then sharply changes back to High. A
High active pulse is a signal that changes sharply from Low to High, maintains a High state for a short period of
time, and then sharply changes back to Low.
If a pulse signal meets the specification for pulse width, the time for the pulse width does not matter.
Pulse width of input signal
As shown in below, input pulse signals that can be received must have a pulse width of 20 msec or more.
Maintain the low state stable for a pulse width of 20 msec.
2
Min. 20 msec
11
Minimum interval between input pulse signals
Min. 50 msec
Proper operation
cannot be
guaranteed.
Min. 20 msec
As shown below, the interval between input pulse signals that can be received should be 50 ms or more.
Proper operation cannot be guaranteed if the input pulse signal is less than 50 msec.
Level signal
A level signal is a signal that maintains a Low and/or High state for a certain length of time, and refers to the
time during which that state is maintained. A Low active level signal changes from High to Low, and the time
during which it maintains the Low state is the active state. A High active level signal changes from Low to High,
and the time during which it maintains the High state is the active state. If both Low and High are significant,
both the Low state and the High state are each maintained for a certain length of time.
Minimum time input level signals that can be received are maintained
As shown below, input level signals that can be received must be maintained for 20 msec or more.

The maximum current that can be provided is
180 mA.
Set a jumper on CN200 to provide an external I/
O power supply, while also keeping Signal
Ground and Frame Ground separate.
Input Pulse/Level Sends an instruction to start printing.
• In pulse mode, printing starts if a change from
High to Low is detected. Detection occurs
only when the state of the "End print" signal is
High, and does not occur while printing is in
progress.
To print a new label, first return the signal to
High, and then change it again from High to
Low.
• In level mode, printing starts if this signal is
Low. Detection occurs only when the state of
the "End print" signal is High. Printing of new
labels will continue until Low is detected.
• Signal logic: Low active

Input Level Sends an instruction to feed the paper.
• When the printer is in the Ready or Pause
state, the printer feeds paper if this signal is
Low.
• For labels, if this signal changes to High while
the printer is feeding paper, feeding will stop
when the edge of the next label is detected.
• For continuous paper, if this signal changes to
High while the printer is feeding paper,
feeding will stop after the detection time has
elapsed.
• Signal logic: Low active
Input Pulse Sends an instruction to pause the printer.
• The printer is paused if a change from High to
Low is detected.
• While the printer is paused, if a change from
High to Low is detected again, the printer will
be unpaused.
• Signal logic: Low active
*3
Input Pulse If the label reprinting function is enabled, an
instruction to reprint the label that was last
printed is sent from an external device.
• The label is reprinted if a change from High to
Low is detected.

• The head is cleaned if a change from High to
Low is detected.

• H: Clogged nozzle not detected
* The results of the previous nozzle check are
applied.
* Even if nozzle clogging is not specified (when
a nozzle check is not performed, or if a warning occurs while the state of the nozzles is
unclear), the value at that time is maintained.
Output Level Indicates whether the printer is in a paper out
state.
• L: Paper out
• H: No paper out
∗1 Input and output directions are described as viewed from the printer.
Input: Signal input to the printer from an external device.
Output: Signal output from the printer to an external device.
∗2 The logic for output signals can be reversed.
The information provided in the Description column is based on the default signal logic.
If the signal logic is reversed, it will be the opposite.
∗3 The logic for input signals is low active. (The logic for input signals cannot be reversed.)
∗4 The "Start print" signal and "End print" signal can be switched between pulse and level.
∗5 The results of the previous nozzle check are applied to the clogged nozzle detected signal (pin 24). Therefore,
during a nozzle check, issue a nozzle check command (pin 14) before checking the clogged nozzle detected signal
(pin 24). Refer to timing "Timing" on page 49.
