. SLIP does not provide error detection
,
being reliant on other high-layer protocols for this. A SLIP connection needs to have its IP address

configuration set each time before it is established.
•
Local IP
IP address assigned to COM port (local point of SLIP protocol) used for p-t-p communication with
Connected device. It has to be within the subnet defined by Peer IP and Peer IP mask.
•
Peer IP
This is IP address of Connected device (remote point of SLIP protocol) on the other end of RS232.
•
Peer IP mask
Peer IP and Peer IP mask defines Subnet, which is routed into SLIP on respective COM.
Note:
Peer IP and Peer IP mask defines IP subnet which is automatically routed to respective COM.
This subnet can not overlap with any other subnet in RipEX defined on Radio, ETH or VLAN.
UNI
UNI is the "Universal" protocol utility designed by RACOM. It is supposed to be used when the applic-
ation protocol is not in the RipEX list and the addressed mode of communication is preferable in the
network (which is a typical scenario). The key condition is that messages generated by the Master
application device always contain the respective Slave address and that address (or its relevant part)
position, relative to the beginning of the message (packet, frame), is always the same (Address position).
Generally two communication modes are typical for UNI protocol: In the first one, communication has
to be always initiated by the Master and only one response to a request is supported; in the second
mode, Master-Master communication or combination of UNI protocol with ASYNC LINK protocol and
spontaneous packets generation on remote sites are possible.
The UNI protocol is fully transparent, i.e. all messages are transported and delivered in full, without
any modifications.
Underlined parameters are described in
•
Address mode
List box: Binary (1 B), ASCII (2 B), Binary (2B LSB first). Binary (2B
MSB first).
Default = Binary (1 B)
RipEX reads the Protocol address in the format and length set (in Bytes).
The ASCII 2-Byte format is read as 2-character hexadecimal represent-
ation of one-byte value. E.g. ASCII characters AB are read as 0xAB
hex (10101011 binary, 171 decimal) value.
•
Address position
Specify the sequence number of the byte, where the Protocol address
starts. Note that the first byte in the packet has the sequence number
1, not 0.
