CAPTER 1 General Description
This chapter provides an overview.
1.1 Overview
When you connect a DP-581H thermal printer to the midi LOGGER series, the logger signals can
be printed on the printer. The waveforms of the input signals can be printed in real time,
numeric values can be printed as a log, and the displayed screen can be printed.
1.2 Features
Portability
By combining the DP-581H thermal printer and the compact midi LOGGER series, you can
create a mobile print environment.
Wireless LAN Connection
The GL840/GL240 midi LOGGER can be connected to a printer through wireless LAN using the
optional wireless LAN unit (B-568).
A variety of print features
Direct Y-T printing can be used to print input signals in real time. Further, the print timing can
be synchronized to triggers.
Data recorded in the past can be played back and printed. The period in which you want to print
can be specified with cursors.
The logging print function allows printing of numeric values such as those in CSV data.

1.3 Operating Environment
The following table shows the midi LOGGER series instruments that can connect to the printer.
If you are already using a midi LOGGER series instrument, you need to update the firmware.
You can download the firmware from the Graphtec website.

printer.
For the procedure to make a Web connection to the printer and that to change the
printer settings through the Web connection, see the printer instruction manual. For the
SSID and key, set the same SSID and key as the logger access point set in step 1-3.

10
3. Printer registration
3-1. Press the MENU key on the logger to open the OTHER menu.
3-2. Under the printer registration, set the interface to use to wireless LAN.
The logger needs to be set to access point mode in advance in step 1-3.
3-3. The printer name will be displayed when you perform a printer search. Press ENTER to
select the printer and complete the registration.
※Check
If the printer name does not appear, check the SSID, encryption method, encryption key, and so
on set in “2. Printer configuration.” Moreover, check the IP address and network mask to verify
that the printer is in the same segment as the logger’s wireless LAN.
4. Test print
4-1. Perform a test print, and check that it is printed properly.
※Check
If the test print fails, check the following.
- Check that the wireless connection between the logger and printer is established. You can
check whether a wireless connection is established with the WIFI setting of the printer.
- Check the printer’s IP address and network mask to verify that the printer is in the same
segment as the logger’s wireless LAN.
- Turn the logger and printer off and then back on.
※If the communication speed decreases due to the communication environment, print data
may be lost.
※When the printer is connected with the logger’s wireless LAN setting set to access point
mode, the WL sensor (GL100-WL) cannot be connected.
※If you want to connect the logger as a client to an off-the-shelf wireless LAN router, set the
wireless LAN setting to station, and set the same SSID and key as the off-the-shelf wireless
LAN router. Then, refer to the procedure for the wired LAN connection.
※Only a single logger can be connected to a printer.

11
Wired LAN connection
To use a wired LAN connection, you need an off-the-shelf wireless LAN router. Obtain it in
advance. Make sure that the off-the-shelf wireless LAN router meets the following
specifications.
IEEE802.11n compatible
Has a wired LAN port
Has a router mode (RT mode)
※Graphtec will not guarantee the operation of the off-the-shelf wireless LAN router or answer
any questions about it.
Required items
DP-581H printer
GL840 or GL980/GL2000 midi LOGGER
Off-the-shelf wireless LAN router

Normally, an off-the-shelf wireless LAN router has an auto network address assignment
function (DHCP), so you can set the “Auto IP address assignment” of the logger to
“Enabled” to automatically obtain the addresses. If the DHCP on the wireless LAN router
is disabled, set the “Auto IP address assignment” of the logger to “Disabled” and set the
addresses.

CAPTER 3 Print Functions
The following main print functions are available.
Direct Y-T printing
Hard copy printing
Memory out printing
List printing
Logging printing
3.1 Direct Y-T Printing
Signals applied to the data logger are printed in real time in the form of waveforms. You can
adjust the chart speed, print in sync with a trigger function, and print comments as you like.
Further, printing is divided into zones according to the logger setting.
Y-T printing without division Y-T printing with divisions

14
3.2 Hard Copy Printing
The contents displayed on the screen are printed on the printer. The color screen is converted
into black-and-white with the dither method and output.
Y-T printing
GL240 Y-T printing In case of black and white reversal
GL240 prints 90 degrees inverted.
XY waveform printing (GL980/GL2000 only)
All screens Waveform screen

15
3.3 Memory Out Printing
A specified period of the recorded data can be printed after the data is played back. Settings
specific to memory out printing are available, so you can adjust them as necessary without
returning to the normal printer settings.

16
3.4 List Printing
The configuration status of the data logger is printed. The following information is mainly
included.
●Model name, firmware version, and other specifications
●Data timestamp
●Various data settings
●Annotation settings, etc.

17
3.5 Logging Printing
Numeric values are printed with the channels in columns and the times in rows in the form of
CSV data. The maximum, minimum, and average values are printed in the last row. The print
direction is different between direct logging and memory out logging.
During direct logging
Direct logging printing is only supported on the GL240 and GL840. Direct logging printing is
performed when data is printed with the screen mode set to digital display. The fastest print
sampling speed is 1 second. Decimation is performed at data sampling settings faster than 1
second. Logic nor pulse signals cannot be printed.
On the GL840, the channel set on the information channel is printed. For the information
channel setting, see “Information channel setting” in chapter 4, “Configuration.”
A “T” mark is printed next to the time in the row in which a trigger occurs. Moreover, an “A”
mark is printed in the channel of the row in which an alarm occurs.
※If Trigger Sync is set to off and the sampling interval is set slower than 30 seconds, the
sampling interval will be offset near the start trigger because trigger detection is
performed at 30-second intervals.

18
During memory out logging
Memory out logging printing is supported on the GL980, GL2000, GL240, and GL840.
During memory out logging, up to 1000 points can be output. A header is printed every 100
points. If you set full-width characters in annotations from the software, they will appear as
blanks. Logic nor pulse signals cannot be printed.
A “T” mark is printed next to the time in the row in which a trigger occurs. Moreover, an “A”
mark is printed in the channel of the row in which an alarm occurs.

19
