Safety Isolated RS-232 Interface
The RS-232 interface of the 4314Ki Igniter Testers is an ultra-safe isolated serial Interface. The digital
signals are transmitted across the isolation barrier using iCoupler technology. The interface provides a
safe way to communicate with the device via a computer or PLC and allows the transfer of single reading
or continuous transmission of data.
Connecting the 4314Ki via RS232
The RS232 interface capabilities:
The RS232 interface provides a point-to-point connection between two items of equipment such as a
computer and the 4314Ki. There are some parameters you need to set on both sides. Once you have set
these parameters, you can communicate with the 4314Ki through the RS232 interface.
•
Baud rate: 115200 baud.
•
Parity bit: none.
•
Data bit: 8 bits.
•
Stop bit: 1 stop bit.
•
Data flow control: none.
Notes for RS232 installation
The 4314Ki is a DCE (Data Channel Equipment) device with a 9-pin D-type shell RS232 connector located
on the rear panel. Table 4 shows the 9-pin connector (Female) with its pin number assignments.

Checking Connections
To test whether the RS232 connection is working, you can send a command from the computer. For
instance, using a terminal program send the query command
Idn?
The device should return the Manufacturer, model number, firmware version in the following format:
Valhalla Scientific 4314Ki V1.0
If you do not receive a proper response from the 4314Ki, please check if the power is on, and all cable
connections are active.
