SN3101 User Manual

Direct Access

The Direct Access function works in conjunction with SN3101 COM ports

whose operating modes have been specified as Real COM, TCP Server, and

Modbus Slave (see Operating Mode, page 37).

If no IP addresses are specified here, any host can open a TCP/IP session to the

SN3101’s COM port and use the SN3101’s IP address and socket base port for

data transmission.

If specific IP addresses are entered here, however, only hosts at those addresses

can open a TCP/IP session to access the port.

To impose limitations on the ability to directly access the affected ports, key in

the IP addresses that will be allowed access.
