Characteristics and basic properties
IP Relay combines two relays controlled over Ethernet and RS-
232 / Ethernet converter. The device can reset a remote device
via Ethernet or switch its power supply on or off. IP relay can be
also used as a remote serial port.
Features
•
Ethernet
- RJ45 (10BASE-T - IEEE 802.3)
•
RS-232 Serial port
(RxD, TxD, CTS, RTS, GND)
o
7, 8, or 9 data bits;
o
baudrate: 50..115200Bd;
o
HW/SW
handshaking
•
Testing software and
virtual serial port
for Windows 2000/XP available on a CD
•
The examples of remote control by
Java, VisualBasic, Delphi
and
PHP
commands
available
•
Two independent relays
controlled via Ethernet by
NVT commands
(M2M protocol).
Standard relay configuration:
o
Relay 1:
Controls breaking contact
leading out the power supply,
output clips can be connected
directly as a power supply for an IP
camera, microwave modem or a
power relay.
o
Relay 2:
Switching contact can be
connected to any RESET button
Other possible contact configurations
can be found in the table at the end of this manual.
•
DIP2 switch
intended for free use e.g. for identification of service works.
•
Possible ways of device configuration
o
RS-232 Setup
(over serial port using any RS-232 terminal - 9600 8N1)
o
UDP Setup
(configuration of basic network parameters)
o
TCP Setup
(remote configuration in the terminal via TCP)
•
Access security and relay control
:
o
You can limit access to the device only from a predefined IP address range
o
TCP connection can be secured using a 128-bit TEA algorithm
•
Metal box dimensions: 25 x 82 x 90 [mm]
The device can be fitted on a DIN molding. We can supply side brackets for wall-mounting
upon request.
