Establishing Console Mode on an Ethernet Slave

Enter serial console mode by holding down the SW-R button while booting up.

The COM B LED will flash to indicate console mode.

Please be aware that doing this causes the processor to boot up in standalone

mode, rather than Ethernet slave mode. You will notice that the Ethernet master

shows this device as being off-line.

To put the processor back in Ethernet Slave mode and use the serial console,

type: REBOOT at the console prompt. This will reboot the processor in slave

mode, and enable the serial console.

NOTE: Booting up in serial console mode will render COM B useless to the

program, as it is being used for the serial console.

To terminate the serial console mode, press the HW-R button, or cycle the

power.

NOTE: Pressing <F10> (or selecting Functions | 2-Series | Hard Reset) in

Toolbox for the master control system may cause errors if both the program and

the console mode are using the same COM port.

For more information on slave mode operation, refer to the latest version of the

2-Series Master/Slave Modes Reference Guide (Doc. 6164).

Troubleshooting Communications

Use the following checklist if communication cannot be established with the

QM-RMCRX-BA.

1. Verify that you are using the correct cables. As described previously,

an RS-232 connection requires a null modem RS-232 cable with DB9

female connectors on both ends. TCP/IP connection requires a CAT5

cable with 8-pin RJ-45 connectors.

2. With a serial connection, verify that the correct COM port on the PC

has been selected. Some computers have more than one COM port;

some may be internal (e.g., for a modem). Consult the manufacturer’s

documentation for further information about the COM ports on your

PC. Ensure that the COM B LED is flashing.
