GENERAL FEATURES
The S16SB (Fig.2) is an extremely practical, easy-to-use desk or panel
printer. It is the ideal solution for all those applications, whether they be
industrial, professional or laboratory-related, in which data has to be
immediately printed out in ticket form: measuring systems, receipts (not for
tax purposes), security, control, diagnosis purposes, vehicles (taxis, trucks),
portable version for measuring and reports of all kinds, and any other
circumstances in which high performance printing is required in tight spaces.
(Fig.1)

INTRODUCTION

S16SB/S16B-IR
The printer is equipped with a 4-pin impact mechanism which uses ordinary
44.5mm paper rolls with a maximum of 16 columns per line, and housed
inside it is a battery which means the printer can be operated without being
connected to an electrical outlet.
The S16SB is so compact, lightweight and economical that it can be
installed extremely easily on any type of equipment.
It has a standard RS232 serial interface.
PRINTER DESCRIPTION
The printer has an ABS casing with a cover which opens to allow access to
the paper roll and print head.
On the front of the panel there is a ON-OFF / FEED key and an LED.
(Fig.2)
1) ON-OFF / FEED key. If the printer is off (green LED off), when this key
is pressed briefly, power is turned on to the printer (green LED blinking).
To turn off the printer, press the key briefly (the LED starts to blink
faster) and if the key is not pressed again within a second the printer
shuts off, otherwise it returns to operational status.

INTRODUCTION

(Fig.3)
If the key is held down during power up, a test receipt will be printed out
giving the default parameters and character font.
If the key is pressed when the printer is on, the paper can be fed
manually.
•GREEN LED: Intermittent blinking of the LED indicates that the printer is
functioning.

1. INSTALLATION AND USE
11- S16SB/S16B-IR
1.1 CONNECTIONS
1.1.1 Power supply
The printer is equipped with an autonomous, rechargeable battery pack for
printing. Recharging is carried out using the J1 mod. DC 1.3mm power plug
which requires a supply voltage of between 9 and 15V.
Inside the printer is a battery recharge circuit. To guarantee optimum battery
recharging, we suggest that the pack be recharged for 8-10 hours.
WARNING
Be sure to follow the battery charger polarity.

1.1.2 Character bit selection
Jumper JP6 (fig.1.1) enables data to be sent to the printer (8 bits per piece
of data,1 stop bit, parity none), in which the most significant bit is not
handled. Jumper setting is given in Table 1.2.

1.1.3 Carriage Return selection
Jumper JP8 (Fig. 1.1) enables the carriage return. If jumper JP8 is closed,
the printer management software ignores the $0D (carriage return)
command code. This procedure is also run by the $0F (CRLF) command.
Jumper setting is given in Table 1.3.

1.1.4 Print direction selection
By means of the jumper JP7 (Fig.1.1), Normal or Reverse print directions
may be selected. In normal printing mode, the characters are printed from
left to right, while in reverse mode the characters are printed upside down
and from right to left. It is always possible to vary this configuration using the
software commands ESC R and ESC N.

1.2 MAINTENANCE
1.2.1 Changing the paper roll
To change the paper roll, proceed as follows:
1) Remove the upper cover (1) of the printer by pressing from behind.
2) Position the paper roll (2) making sure it unrolls in the direction indicated
in the drawing below.
3) Insert the end in the printing mechanism opening (3) and press the
FEED key (4) until the paper edge emerges 3 or 4 centimeters.
4) Replace the upper cover and tear off the paper.

2.1 RS232 / TTL SERIAL
The printer is equipped with an RS232 or TTL serial interface that is
connected using a 9-pin female connector.
In the serial protocol, the signals relating to communication are RX and RTS.
The reception format is fixed at 8 data bits, 1 stop bit, parity none. It is,
however, possible to vary reception speed by using jumpers JP1 and JP2.
The table below describes the pins of the 9-pin external rectangular
connector, or the points to which the user must connect, if not using the
connector:

Jumpers JP4 and JP5 select the speed at which the RS232 receives the
data. This setting is read by the printer software immediately after a reset
(hardware or software). Any changes made in the configuration while the
printer is operating will not, therefore, produce any effect.

As can be seen in figures 2.3 and 2.4 the RS232
standard signal (+12 / -12 V) is inverted with
respect to the TTL standard signal (0 - 5 V).
During data transmission it is extremely important to
test the RTS line in order to check whether the
printer can receive data. When the printer is ready
to receive, the RTS line is in a “high” logic state
(+12 V) for the RS232 standard (Fig.2.3) and in a
“low” logic state (0 V) for the TTL standard
(Fig.2.4); when the printer is busy, the RTS line is in
a “low” logic state (-12 V) for the RS232 standard
(Fig.2.3) and in a “high” logic state (+5 V) for the
TTL standard (Fig.2.4).
Before sending any data, the device which
transmits data to the printer must ensure that the
RTS line is in a “high” logic state when the RS232
standard is used, or in a “low” logic state when the
TTL standard is used.
If this structure is not adhered to, data could be lost.
Fig.2.2 gives a sample flow chart for data
transmission using RS232 standard.

The diagram in Fig.2.3 illustrates the status of the RX and RTS lines
required to ensure good communication with RS232 standard, and Fig.2.4
illustrates the status for good communication using TTL standard:

2.2 INFRARED
Data is received through an infrared photo transistor that normally has a band
width of 890nm. The transmitter, whose band must be equal to that of the
receiver, can be a photodiode or traditional light source such as an LED or 7-
section red display. The distance of the optic link depends on the brightness
of the source: if a photodiode is used, this distance is ..... with a power supply
currentof.....;if an LED orreddisplayisused,thisdistance is reduced according
to the characteristics of the transmitters.
“1” is defined as signal presence at the start of the first half of the half bit time
followed by signal absence for the second half of the half bit time.
“0” is defined as signal absence at the start of the first half of the half bit time
followed by the signal for the second half of the half bit time.
The time of a half bit is 2mSec, therefore a signal pulse lasts 1mSec and a
time bit lasts 4mSec.
The start bit is composed of three signals at the start of the first half of the half
bit time. After having transmitted an entire data item, an interval equal to 3 half
bit times must elapse before sending the next one (Delay).
A character is composed of 8 data bits and 4 error correction bits for a total of
12 bits. The correction bits are codified in the same way as the data bits. Each
correction bit is used as an even parity bit for four distinct groups of data bits.
These four groups are indicated in Table 2.2.

For example, the first correction bit (bit 11) must be transmitted as 1 if the
number of 1 in bits 6, 5, 4 and 3 is uneven, making the total of 1 an even
number.
Example: if we wish to transmit ASCII character “A” corresponding to the binary
configuration “01000001”, the error recovery code will be “1101”. The
complete frame will thus become “110101000001”.

Before starting to transmit a data sequence, a start of string character must be
transmitted to synchronize the reception hardware. This character is ASCII
“SYN” corresponding to decimal code 22 or hexadecimal 16. For example, to
send the string Custom, transmit:
“SYN” “C” “u” “s” “t” “o” “m”
Each time data transmission is interrupted for more than 50mSec, the “SYN”
character must be used to re-synchronize reception.
