CN2510 User’s Manual Troubleshooting

A-4

Question: My application involves connecting the console port of a CISCO router/switch to a

Moxa Async Server serial port. I connect to the CISCO router/switch console by Telnet over

the network from a remote site. Why does the CISCO router/switch receive two “Enter＂

commands even though I only pressed the “Enter” key once?

Solution:

¾ The “Enter” Map keys of Async server are <CR-LF>, causing the CISCO router to receive

two commands instead of one.

¾ Access Async server.

¾ Access Async server serial console to change the “Map keys” type from <CR-LR> to

<CR>.

Terminal Port Problems

Problem: When a terminal is connected to one of CN2510’s serial ports, no message is

displayed on the terminal attached to the CN2510 terminal port when it is powered on.

Solutions:

¾ One of the possible reasons is that this serial port is configured to Disable mode, or to

another application mode. Using the Serial Console or Telnet Console, select Port Æ

Mode, and then move the cursor to the Application corresponding to the serial port, and

change Disable to Terminal.

¾ Check to see if the terminal’s serial port is set to the same settings as CN2510’s serial port.

Use Serial Console or Telnet Console, select Port Æ Line, and then move the cursor to the

corresponding serial port, and check to see if Speed, Bits, Stop, Parity, FIFO, RTS/CTS,

XON/XOFF, and Discon.ctrl settings are the same as the terminal’s serial port.

¾ Check to see if the RS-232 cable is wired correctly. If the port is utilizing RTS/CTS

hardware flow control, then the RTS, CTS pins should be included. In this case, a cable

with only TxD, RxD, and GND pins will not work.

¾ The terminal may be unlocked by pressing [Ctrl-S] (Hex Code 0x13) if software flow

control is used. Press [Ctrl-Q] (Hex Code 0x11) to relieve it.
