4.4 - Outputs
the interface is equipped with 4 relay outputs rated for a maximum current of 2A 30V DC or
2A 250V AC. Fig. 3 shows an example hookup to the first output (OUT 0).
Note – If the board is switched off and then on again, the relays do not reacquire their pre-
vious values but start from their default values (normally open).
5 - SERIAL CONFIGURATION
The device can be connected to a PC running a terminal emulator. The RS232 port must
be configured as follows:
• Baudrate: 115200
• Parity: None
• Data bits: 8
• Stop bits: 1
• Flow Control: None
6 - IP CONNECTION
The serial interface is emulated via TCP/IP. Up to 4 connections can be opened at the same
time in addition to the serial connection. The default settings are:
• ip-address: 192,168,100.1
• subnet-mask: 255.255.255.0
• default gateway: 192.168.100.254
• tcp-port: 23
The IP configuration can be modified via a serial connection RS232, using the NET command.
7 - COMMUNICATIONS PROTOCOL
The serial interface and tcp/ip connection allow you to control the device with the following
commands. The protocol syntax is as follows:
<COMMAND> <Flag> <Parameters>
The components of the this string have the following meanings:
<COMMAND>
Identifies the command to be executed or associated information.
Identifies the action associated with the command. The protocol pro-
<Flag>
vides for the following values:
