&G: Char. Transmit Delay 0 – Off
For controlling units with small RS232 buffer, it is sometimes advantageous to keep relatively high
baud rate but insert delays between individual characters. The delay is defined in
milliseconds
and
it is defined as the time between the starts of individual characters; so, for 2400 Bd a 2ms delay has
no effect since the character starts are 2.4 ms apart.
&H: Tx Control
Tx FULL duplex
When HALF duplex is activated, the Device assumes unidirectional medium connected to the serial
line (e.g. RS485) and won't start transmitting data while receiving.
0: FULL duplex
1: HALF duplex (RS485)
Other device parameters
===== Security Setup ======
%A: TCP autorisation
Off
Activates TEA authorization, which is requested from the remote side after the connection is
established.
0: TEA authorisation Off
1: TEA authorisation On
%K: TEA key 0:01:02:03:04 1:05:06:07:08 2:09:0A:0B:0C 3:0D:0E:0F:10
To set the TEA key, use the “%K” option. Set 16 bytes in quadruples using four hexadecimal values
separated with colons. The first string defines 0-3rd quadruple of bytes. So, to set the last 4 bytes to
the displayed value, use „
%K 3:0D:0E:0F:10
“.
%S: TCP/IP setup On
Allows or denies the remote configuration using TCP setup on port 99.

From a whole
I/O Control Setup
section the IP relay only uses the
#A: Power Up INIT
command,
which can affect directly the states of output relays on the device reset and thus compensate an
improper relay configuration. Parameter #A is inserted as a DECIMAL value of the IP relay’s
controlling 8-bit port.
