6.3.1.10 Serial Passthrough
The Network > Serial Passthough screen allows you to change the configuration for the passthrough
application that provides a gateway between a conventional RS232/RS485 serial interface and a TCP
socket.
Figure 6-

1: Network > Serial Passthrough
Enabled:
Default value is “
Disable
“.
Physical:
Specifies the physical interface as either “
RS232
“ or “
RS485
“. This value does not change the
physical interface but rather, it defines the actual hardware configuration that is present. You must be
certain of the hardware configuration before making this change.
Note: ‘serial0’ is the only device capable
of RS485 currently.
Duplex:
Specifies the RS485 duplex as either “
Half
“ or “
Full
“. This value does not change the physical
interface but rather, it defines the actual hardware configuration that is present. There is a jumper on the
RS485 daughterboard that is responsible for this value. Refer to section 3.2.3 for more information.
Baudrate:
Specifies the number of symbols per second transferred.
Effective Baudrate:
Disabled by default (“
0
“) but can be used to slow the transmission of data as the
receiver cannot keep up with the speed of the transmitter.
Data bits:
Specifies the actual number of data bits sent in a character frame.
Parity:
Additional error checking on serial data transfer.
Stop bits:
Specifies the number of stop bits in a serial character frame.
Device:
Specifies the physical RJ45 serial connector on the GridRouter.
TCP Port:
Specifies the TCP/IP port number.
TCP Buffer Timeout MS:
Specifies the timeout in milliseconds for the TCP buffer to output flush.
TCP Buffer Size:
Specifies the buffer size for TCP transmission.
TCP Idle Timeout:
Specifies the number of seconds a TCP connection is allowed to remain idle before
the port is closed.
