1-3. Overview
SI-65, SI-65A, and SI-65FA are communication converters which convert asynchronous
communication on RS-422/485 into TCP/IP or UDP/IP communication on Ethernet.
These converters have built-in Lantronix XPort at the LAN interface part and the RS-
422/485 interface supports 4-wire full duplex and 2-wire half duplex. Thus It can be applied
to various systems which requires liability. You can control the device which has a serial
port from a PC on the network by socket communication. By using COM port redirector,
which is included in the CD-ROM, you can use it like com port communication. It is also
possible to extend the serial line without PC by connecting the two devices by LAN.

Chapter 2 SI-65(A/FA) Usage
2-1. SI-65(A/FA) Overview and Features
SI-65 is a DC powered model. SI-65A is a DC powered model which is adaptive to cold
district. SI-65FA has a built-in AC power supply and has a insulator between the interfaces
(Ethernet and the RS-422/485). These three models have the same function as to the conversion
function. You can set an IP address to the converter and the converter communicates with the
Ethernet device by TCP/IP or UDP/IP. When it receives data from serial side, it transmits the
data by putting it on the data part of the TCP/IP or UDP/IP packet. When it receives data from
the Ethernet side, it extracts the data part of the TCP/IP or UDP/IP packet and transmits it to the
serial part.

SI-65(A/FA) Line Monitoring Function
RS-485 communications of two-wire half duplex is required to send data after conrming
that any devices have not sent data into the RS-485 line. The line monitoring function
allows to detect that any devices have not sent data into the RS-485 line, and to conduct
the ow control. To use this function, the ow control of built-in XPort is required to set to
CTS/RTS (Hardware).
RS-485 Line Condition Flow Control Condition
The period of time from when to detect a space bit of the data
in the RS-485 line sent by another device, to when not to get
to continuously detect a space bit over internal timer time of
the converter, while the RS-485 driver of the converter is not
active.
Prohibits sending data
from the converter to the
RS-485 circuit.
The period of time when not to detect a space bit in the RS-
485 line which another device continuously sends over
internal timer time of the converter, or when the RS-485
driver of the converter is active.
Permits to send data from
the converter to the RS-
485 circuit.
*This function allows the ow control to operate in a direction of sending only. The
ow control in a direction of receiving does not operate.

This setting makes the converter operate in the half duplex RS-485 mode. Communicated
data is sent and received through SD/RD+ and SD/RD- terminals.
SW-B No.2 (Echo Back Setup)
Selects the echo back specication for the half duplex RS-485 mode.
OFF(Echo Back)
Echo back the data which is sent from the converter to the RS-485 line. The full
duplex RS-422 mode does not echo back data even when this switch is in the OFF
setting.
ON(No Echo Back)
When you communicate in the half duplex RS-485 mode, setting this switch to ON
prohibits the data, which is sent from the converter to the RS-485 line, is echoed back to
the LAN host. Therefore, while the driver is active, the ON setting makes the receiver
non-active.
* Be sure to set this switch to OFF in the full duplex RS-422 mode.
SW-B No.3 (Terminal End Between SD+ and SD-)
Setting this switch to ON inserts the terminator 100 ohm between SD+ and SD- (terminal
block 1, 2) in a direction of parallel.
SW-B No.4 (Terminal End Between SD/RD+ and SD/RD-)
Setting this switch to ON inserts the terminator 100 ohm between SD/RD+ and
SD/RD- (terminal block 3, 4) in a direction of parallel.
*1 Press down the DIP switch to switch on and press up to switch off.

2-7. SI-65(A) Power Source
There are two ways to supply power to SI-65/SI-65A.
Supply by AC
1. Connect the plug of the AC adapter to the DC jack (DC-IN) of SI-65/SI-65A.
2. Plug the AC adapter to an AC outlet to supply power.
Please use appropriate AC adapter which complies with the power specication and safety
standards of the country in which you use SI-65/SI-65A.
Model Power specication Safety standards
VFN-650B AC 100V ± 15%, 50/60 Hz PSE
6A-181WP09 AC 90 - 264 V, 50/60 Hz PSE/UL/CUL/GS/CCC/CE
Note: When using VFN-650B (AC adapter), power consumption of AC is about 4.9VA for SI-65 and
about 3.7VA for SI-65A.
The operating temperature of the VFN-650B is from –10 to +50 degrees Celsius. When using SI-
65A at the temperature of –25 to –10 or +50 to +75 degrees Celsius, please do not use the AC
adapter. Prepare a DC source which is appropriate for the environment.
Supply by terminal block
(In the case of SI-65)
1. Prepare DC source of 5 - 12V (DC 5 - 9V is recommended), 4W or more.
* Current consumption of SI-65 is up to 300mA regardless of supply voltage.
External source of lower voltage is recommended. Because the more voltage is,
the more power consumption and heat tend to be.
2. Connect the 6th pin of the terminal connector with the plus pole of the external
source and connect the 5th pin with the minus pole (GND) of the source.
* Please use a cable of AWG22 - 14. Bare the end of the cable for 6mm, which is
to be connected to the terminal block. Please do not make offset when you use
twisted wire.
(In the case of SI-65A)
1. Prepare DC source of 5 - 30V, 2W or more.
* Current consumption of SI-65A is up to 330mA when DC is 5V, 130mA when
DC is 12V and 60mA when DC is 30V.
2. Connect the 6th pin of the terminal connector with the plus pole of the external
source and connect the 5th pin with the minus pole (GND) of the source.
* Please use a cable of AWG22 - 14. Bare the end of the cable for 6mm, which is
to be connected to the terminal block. Please do not make offset when you use
