Moxa Technologies C360 manual Rts Dsr Cts Dtr, Solution

Technical Reference ∙ ∙ Appendix B

aIn the UNIX system, C360 will check line status (CTS/DSR) before it sends data out if RTS/CTS flow control feature is set to

ON. In this case, if user is using 3-pin (TxD, RxD, GND) cable, please run "moxaadm" and use configuration program to set the RTS/CTS flow control feature to OFF (strongly recommended). Or loopback (or short) the RTS with CTS and DTR with DSR on MOXA port site as follows.

RTS	DSR
CTS	DTR
	DCD

If RTS/CTS flow control feature is set to OFF, then leaving the pins mentioned above open is fine.

bPerhaps the application controlling MOXA board is not correctly written according to the corresponding API of the operating system. To verify, please run existed and known good application or Moxa- provided utility.

For example, under UNIX, "stty", "cat", or "getty" is existed program for testing tty port.

4During operation, the host system with C360 is powered off but the Async Concentrator(s) is(are) still on.

Solution:

Simply restart the host system, and normal C360 startup procedure will be executed.

5Under UNIX, MOXA port responds too slowly or abnormal key operation.
