IS 1314i/1412i/1512/3434i’s IP ADDRESS SET BY DHCP?
This determines whether the IP address of the Monitor is fixed or if the IP
address is set by DHCP.
DHCP is a server on the Ethernet network who automatically assigns IP
addresses to Ethernet devices on the network.
1314i/1412i/1512/3434i’s IP ADDRESS
If the IP address is not set by a DHCP server (as selected in the previous
setup) the IP address of the Monitor can be entered manually.
1314i/1412i/1512/3434i’s IP PORT NUMBER:
The IP port number where communication between the Monitor and host PC
goes through. The default port number is 23.
PROTECTED IP ADDRESS
This sets the IP address of the host PC, who is allowed to communicate with
the Gas Monitor.
If the value is 000.000.000.000 the any host PC is allowed to communicate
with the Gas Monitor.

Data Lines
Pins 2 and 3, Transmitted Data and Received Data, are data lines. For data
lines, RS–232 specifies that:
•A voltage below –3V signifies a binary 1
•A voltage above +3V signifies a binary 0
•When a data line is passive, it is held in the binary 1 condition.
Data transmission is asynchronous as shown in Fig. 1.10.

BB6032-14 Photoacoustic Gas Monitor LumaSense Technologies
1314i / 1412i / 1512 / 3434i Page 17 of 81
The data is transmitted in the form of ASCII codes. All ASCII codes given in
the following text are decimal numbers.
Control Lines
Pins 4, 5, 6, 8 and 20 are control lines. For control lines, RS–232 specifies
that:
•A voltage above +3V signify the “on” state.
•A voltage below –3V signifies the “off” state.
The use of the control lines is described in section 1.4.2.
1.4.1Interconnection
A null-modem cable must be used to interface the Monitor to another DTE-
coupled device (computer or printer), so that the DTEs appear to each other
to behave like modems. The null-modem cross connections which should be
used with the Monitor are given in Fig. 1.11.
Fig. 1.11 Null-modem cable details (9-pin to 9-pin connectors)
1.4.2Interface Set-up
The Set-Up tree enables you to specify the RS-232 interface set-up of the
Monitor. The selections are :SET-UP — CONFIGURATION — SYSTEM —
COMMUNICATION — RS–232–C.
WARNING! You must partially reset the Monitor if the RS–232 configuration
is changed, for example, if the baud rate is changed. See the Instruction
Manual for details.

BB6032-14 Photoacoustic Gas Monitor LumaSense Technologies
1314i / 1412i / 1512 / 3434i Page 18 of 81
Baud Rate
The baud rate is the speed of data transmission. Possible baud rates are
300, 600, 1200, 2400, 4800 and 9600 bits/sec.
Parity
Checking the parity of a transmitted byte is a way of detecting transmission
errors. Possible set-ups are:
•Even
•Odd
•None
Even (odd) parity means that a transmitted byte must contain an even (odd)
number of binary 1’s. To achieve this, one extra bit — the parity bit — is
added to each byte transmitted. When “None” is selected, no parity check is
performed.
Stop Bit
The stop bit is used to terminate a transmitted character (see Fig. 1.10).
Together with the start bit, the stop bit frames the data bits and is used to
synchronise data transmission. The Monitor can use either one or two stop
bits.
Data Bit
The number of data bits determines how many bits are transmitted for every
byte of data. Possible set-ups are 7 or 8 data bits to a byte.
Handshake Method
The handshake method is the method used by the Monitor and the external
device to synchronize their transmissions. Three possible set-ups exist:
•X-On/X-Off handshake
•Hardwired handshake
•None
When X-On/X-Off handshake is used, the Monitor transmits the X-Off
character (ASCII 19) when it can handle no more input data. When the
Monitor is once again ready to receive data, it transmits the X-On character
(ASCII 17) over the interface. Similarly, when the Monitor receives an X-Off
character during a transmission, it stops transmitting until it receives the X-
On character. If the X-On character does not arrive within 30 seconds, the
Monitor regards the transmission as aborted and issues a time-out warning.
In Hardwired-handshake mode, the Monitor sets the DTR control line (pin
20) off when it will accept no more data. When it is ready to receive more
data, the DTR line is set on. When the external device sets the DSR control

_________________________________________________________________________________________
BB6032-14 Photoacoustic Gas Monitor LumaSense Technologies
1314i / 1412i / 1512 / 3434i Page 19 of 81
line (pin 6) off, the Monitor stops transmitting until DSR goes back on. If the
DSR line remains off for more than 30 seconds, the Monitor issues a time-
out warning.
If “None” is selected, handshaking is disabled.
If either “Hardwired” or “None” is selected and the external device attempts
to use X-On/X-Off handshaking, the Monitor displays a warning. Similarly, if
“X-On/X-Off” or “None” is selected and DSR is set off by the external device,
a warning will appear.
Hardwire Mode
This parameter determines how the Monitor uses the control lines of the
interface. Three set-ups exist:
•3–Wire mode
•Switched–Line mode
•Leased–Line mode
In 3–wire mode, only the data lines are used. All control lines are ignored.
This means that X-On/X-Off handshake is the only handshake method
available.
In Switched–Line mode, the CTS and DSR control lines are monitored. If one
of the two control lines is set off, data transmission from the Monitor is
blocked. It is recommended that the external device uses the DSR line for
handshaking.
In Leased–Line mode, the CTS, DSR and DCD control lines are monitored.
CTS and DSR have the same effect as in Switched-Line mode. If the DCD
input control line goes off, the Monitor ignores all incoming data.
1.4.3Transmission Interrupt
If the Monitor receives a Ctrl-C (ASCII 3) character over the interface during
transmission of data, the transmission will be aborted.
