CN2610 User’s Manual Troubleshooting

A-4

¾ MOXA does not recommend that you setup 2 LAN ports in the same physical network and

subnet. You might encounter unpredictable outcomes. We suggest that you connect 2

different NICs to different networks.

We do NOT recommend

this type of connection.

192.168.0.2

192.168.0.1

192.168.0.5

CN2610

16 port RS-232 Async Server

2. First, connect CN2610’s LAN1 and LAN2 to the same hub or switch. Configure IP

addresses as 192.168.0.1 and 192.168.0.2, and subnet as 255.255.255.0.

3. Connect one of the hosts on the network to the same hub or switch, and configure its IP

address as 192.168.0.5, and subnet as 255.255.255.0.

4. When you set up CN2610 like this, we assume that you expect the 2 NICs to be load

balanced. This generally means that both connections transmit at the same time. However,

when a CN2610 is configured in this way, there is only 1 IP that is involved in the

transmission.

5. You might have another expectation when setting up the CN2610: to setup a fail over

(redundant) connection. Generally, redundancy means that a NIC has 2 network interfaces

connecting to 2 different switches or hubs. When one of the connections, switches, or hubs

fails, the other one will take over. This definition of redundancy differs from the one used

in MOXA CN2610. MOXA CN2610 has 2 MAC addresses, and 2 IP addresses, which are

independent from each other unlike the general definition in which only 1 MAC address

and 1 IP is involved.

Terminal Port Problems

Problem: When a terminal is connected to one of CN2610’s serial ports, no message is

displayed on the terminal attached to the CN2610 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 CN2610’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.
