&G: Char. Transmit Delay
0
– Off
When controlling devices with a small RS232 buffer, it is sometimes advantageous to keep a
relatively high baud rate but insert delays between individual characters. The delay is specified in
milliseconds
and defines the time between the starts of individual characters. Therefore, delays
under 2 ms have no effect at 2400 Bd because individual characters are 2.4 ms apart.
&H: Tx Control
Tx FULL duplex
When HALF duplex is activated, the converter expects unidirectional communication over the serial
line (RS485) and never starts to transmit data while receiving.
&Q: EOT Trigger character
26
Packet termination character. The default is 26 (ctrl-Z in ASCII). In common operating systems, ctrlZ
is the EOF (End Of File) character. When this character is received from the serial line, the device
does not wait for the “&T” timeout and immediately sends everything as a packet over LAN.
%S: TCP/IP setup
On
Enables or disables remote configuration through the TCP Setup at port 99. This command only
works in the
RS-232 Setup
mode.
0: TCP Setup disabled
1: TCP Setup enabled
(TCP server at port 99)
0: FULL duplex
(RS-232)
1: HALF duplex
(RS-485)
