HD40.1 -3-V2.0
INTRODUCTION
The HD40.1 is a lightweight, compact, portable thermal printer. The connection to the
instruments or to a PC is made through the RS232 serial input.
A careful design allows you to replace the thermal paper roll in a few seconds.
A four NiMH rechargeable battery pack provides power supply and ensures long
autonomy: it is possible to print up to 3000 lines at full charge.
Standard thermal paper roll width: 57 mm.
Print resolution :203 dpi
Print characters (each line): 24
Protection degree: IP40.

1. STATUS Led: shows the printer status.
2. MENU key: advances paper by two lines. When you turn on the printer, if you
press the Menu key and the ON/OFF key, you activate the printer configuration
mode.
3. Cover that gives you access to the paper roll and the printing mechanism.
4. POWER Led: provides information on rechargeable battery status.
5. ON/OFF Key: switches on and off the printer. If you press it with the MENU
key, it gives you access to the configuration mode.
6. Power supply connector. The positive pole is in the middle .
7. 9-pole D-Sub male connector for RS232 serial connection.

HD40.1 -6-V2.0
KEYBOARD AND LED DESCRIPTION
Press the ON/OFF key until the Status led starts blinking to turn on the printer, then
release the key.
Press the ON/OFF key until the Status led remains on to turn off the printer, then
release the key.
To access the configuration mode, press the ON/OFF key and the MENU key to turn on
the printer: when the paper roll starts advancing, release both keys (see chapter
Printer Configuration).
When the printer is on, press the MENU key to advance paper by two lines.
When you turn on the printer, press the MENU key with the ON/OFF key to activate
the printer configuration mode.
The POWER Led provides information on the rechargeable battery status.
When you connect an external power supply, the printer checks rechargeable battery
status and, if necessary, it starts charging batteries.
A pre-charge phase may precede the real charge to avoid excessive stress on
batteries when they are significantly discharged, or their temperature is too low: in
this phase the POWER led blinks every second.
After this first phase, the quick charge starts: the POWER led remains on and it turns
off when the battery is fully charged.
At this point, it is possible to disconnect the external power supply and use
rechargeable batteries only.
Warning: if you connect an external power supply and the POWER led turns off
immediately instead of lighting, it means that there is a fault or there are no batteries.
The STATUS led shows the printer status. If the led blinks every two seconds, it
means that the printer is on and ready to print. If you disable the automatic switch -
off, the led blinks twice every two seconds (to set automatic switch-off, see chapter
Configuration).
To turn off the printer, press the ON/OFF key until the STATUS led stops blinking and
remains on: now you can release the key. The printer turns off.
The following table shows different POWER and STATUS led combinations.

HD40.1 -8-V2.0
INSTALLATION AND USE
CONNECTIONS
The printer has one input (1) for the battery charger power supply and one plug (2)
for RS232 serial connection.
Power supply connector
The power supply connector is 5.5 mm in outer diameter and 2.1 mm in inner
diameter.
The positive pole is in the middle
The printer is provided with the SWD10 power supply which features:
•Output voltage: 12 Vdc
•Maximum current: 1A.
The printer is supplied with a four 1.2V rechargeable battery pack located in the
battery compartment: the printer does not work without batteries.
See at the following chapters how to charge batteries.
RS232 serial connector
The printer is equipped with an RS232 serial communication interface with 9-pole D-
sub male connector (2).

HD40.1 -9-V2.0
A null modem cable is necessary to connect the printer to the instrument: use the
HD2110CSNM cable for instruments with 8-pole Mini DIN connector (e.g. HD21…
series).
Use the 9CPRS232 cable for instruments with 9-pole connector (e.g. HD25.2, etc.).
HOW TO LOAD THE PAPER
The printer uses thermal paper rolls which are 57 mm wide and max. 32 mm in
diameter. Loading thermal paper roll is easy and quick.
Follow the steps below to replace the paper roll:
1) Pull the lid to open the cover.
2) Insert the paper roll according to the sense of rotation as shown below.

HD40.1 -10 -V2.0
3) Pull the paper and close the cover centring the paper roll.
4) Tear off excess paper. The printer is ready.
BATTERIES
HOW TO CHARGE BATTERIES
Use the SWD10 battery charger supplied with the printer to charge batteries.
Follow the steps below:
•Connect the battery charger plug to the mains and the battery charger connector
to the socket in the rear of the printer.
•If batteries are extremely discharged or temperature is too low, the POWER led
blinks for a few seconds (pre-charge) and then it remains on to indicate printer
quick charge.
•Charge the batteries until the POWER led turns off.
•Now the printer is ready: disconnect the battery charger cable.
Note: The first time you use the printer, you need to fully charge batteries.
NOTES ON BATTERY USAGE
•A new NiMH battery performs best only after fully discharging and charging it at
least twice or three times.
•Battery autonomy changes significantly depending on printing intensity and
quantity. Even a charged battery will eventually discharge if unused.
•The battery may be charged and discharged hundreds of times, but the battery will
eventually become exhausted. When autonomy (both when printing and waiting) is
far lower than usual, battery pack needs replacing.
•Use only the BAT-40 Delta OHM battery pack and charge it by using the SWD10
battery charger, or alternatively, one complying with our technical specifications.
•NiMH batteries last longer if you discharge them completely from time to time.
•Extreme temperatures may negatively affect battery performance.

HD40.1 -11 -V2.0
HOW TO REPLACE BATTERY BACK
Follow the steps below to replace the battery pack:
•Disconnect the external power supply and turn off the printer.
•Unscrew (2) the battery compartment cover located at the bottom of the printer
(1).
•Remove the connector. Make sure you don’t tear wires.
•Remove the battery pack.
•Plug the connector to your new battery pack: a notch on the connector will help
you insert it correctly.
•Position the pack in the battery compartment.
•Screw the battery compartment.
BATTERY DISPOSAL
Recycle or dispose of batteries properly.
Do not throw batteries in the dustbin.
Do not throw batteries into fire.

HD40.1 -12 -V2.0
PRINTER CONFIGURATION
The printer operating parameters are as follows (factory values have been
underlined):
1. Interface selection: RS232
2. RS232 serial communication baud rate: 9600, 19200 or 38400.
3. Automatic switch-off delay: 0, 5, 10 or 15 minutes.
4. Printing density: -2, -1, 0, +1, +2.
Please follow the steps below to change these parameters:
•When the printer is off, press the MENU key and the ON/OFF key until the printer
turns on and the paper roll advances. The first parameter you want to change will
appear.
•Press the MENU key to change a parameter: the new value is printed.
•Press the ON/OFF key to confirm a parameter that you selected and go to the next
one.
•Finally, after confirming the last parameter, the printer exits the configuration
menu.
PRINTING PARAMETERS IN DETAIL
1. Baud Rate
The baud rate is the RS232 serial port communication rate, expressed as bit/second.
The following values are available: 9600, 19200 and 38400 baud.
2. Automatic switch-off delay
When this interval of time has elapsed, the printer turns off automatically if you have
neither entered any command nor pressed any key.
You can set the following intervals: 0 or 5, 10 or 15 minutes. If you choose 0, the
automatic switch off is disabled and the printer turns off only if you press the
ON/OFF key.
3. Printing density
This parameter allows changing the intensity of print character. “0” is the standard
value, -2 and -1 reduce intensity, +1 and +2 increase it.

HD40.1 -13 -V2.0
RS232 SERIAL INTERFACE
The printer has an RS232 serial interface with a 9-pole RS232 connector located in the
rear of the printer. Two different connection cables are available on request according
to the device you want to connect - instrument or PC -:
•9CPRS232: is a 9 pole – 9 pole cable for any instrument with standard serial
connector and for PC connection. It is also suitable for other brand instruments.
•HD2110CSNM: is a 9 pole – 8 pole MiniDIN cable for Delta OHM instruments
equipped with this connector (e.g. HD21…).
