•Serial I/O Interface: RS-232:TxD, RxD for data stream, no flow control

RS-232 (RTS/CTS): TxD, RxD for data stream, RTS/CTS for flow control

RS-232 (RTS/CTS, DTR/DSR): TxD, RxD for data stream, RTS/CTS for flow control. DTR for socket status, DSR for socket open/close control

RS-485 (Half duplex): Half duplex RS-485 interface

RS-422 (Full duplex): Full duplex RS-422 interface

•Packet mode of serial input: Packet mode could be in enabled/disabled mode. If packet mode is enabled, the data input from UART will be deferred until the

input buffer is full, or NETRS2321E detects a 10-character packet gap and no more characters have arrived. The block waiting time is extended, to avoid splitting the complete packet.

•Device ID: User assigned ID number for NETRS2321E. Available ID range includes 0-65535

•Report device ID when connected: In TCP mode, if this parameter is enabled, every time the socket is connected, NETRS2321E will immediately report its device ID in the following formats:

Serial #1 - nnnnnA[LF][CR] Serial #2 - nnnnnB[LF][CR] Digital I/O - nnnnnC[LF][CR]

The total length is 8 bytes, where “nnnnn” is a 5-digit device ID, assigned by the user; [LF] is decimal 10; [CR] is decimal 13.

•Setup password:Administration password used to login to the Controller Setup page. It may be left as empty, or up to 15 characters long.

•Access password: During socket connection, the Access/Authentication password may be empty or up to entered as 15 characters long. If the Access password is left empty, authentication is disabled. Otherwise, the authentication will proceed as normal. If authentication fails, or no password is supplied within 10 seconds, the socket will be closed.
