Insys WLAN Serial 11-02-01-06-02.004 ユーザーズマニュアル

Implementation and Configuration INSYS WLAN serial 

25  

Handshake 
The handshake controls the data flow at the serial interface while the data rate is too 
high at the moment. Hardware handshake uses the separate control lines RTS/CTS of the 
serial interface. 
Without handshake, overflowing data is ignored. 
 
Attention!   Handshake must be deactivated when the INSYS WLAN serial is operated 

with a device that does not support the according handshake. 

 
DTR Behavior 
The control line DTR of the serial interface 
indicates whether a device (configuration PC, 
control) is connected with the INSYS WLAN 
serial and whether it is active. The setting 
controls the behavior when the DTR signal is 
missing, e.g. when the terminal device (PC, 
control) is disconnected. 
When the DTR signal is missing, a data 
connection can automatically be terminated, or 
a reset can be performed. 
 
Attention!   The DTR function must be 

deactivated (no DTR behavior) when 
the INSYS WLAN serial is operated 
with a device that does not support 
DTR. 

 
Connection 
In this field, the device can be set to automatically establish the connection. 
In addition, the data stream can be monitored via the idle connection control (Data 
Transmit Control). There is a possibility to terminate the connection when no data was 
transmitted within a previously set time period. When the time period is zero, or nothing 
has been entered into the window, the data stream monitoring is not active. 
 
Responses 
The response format of the INSYS WLAN serial after an AT command or a system 
message (CONNECT, NO CARRIER, OK, etc.) can be set as text or numerical code; it 
can also be switched off, if necessary.
