3.4 Using the Command Line Interface (CLI)

3.4.1

Differences between Serial and SSH

Serial and SSH both present identical management capabilities, but the method of access is different for
each. Serial involves an RS-232 serial connection from a PC to the unit's COM port. SSH uses an
Ethernet PC connection to the unit's ETH port. Maximum recommended cable length for a serial
connection is 50 feet (15 meters). SSH can be connected to the unit from any network point that has
connectivity with the PC, including remotely over the Internet, or using other networks.
The focus of these instructions is on Serial access, but SSH may also be used by following these
additional points, which replace Steps 1-3 below:

Connect to the unit with a PC that is in the same IP network as the MCR. Launch an SSH client
program and connect to the unit using its programmed IP address.

The default IP address for the unit is 192.168.1.1. If you do not know the current IP address of the
unit, follow the serial configuration instructions below, where you can determine the address and
continue configuration, or check with your network administrator.
3.4.2 Establishing Communication—Serial Interface
Follow these steps to configure the unit for its first use with serial console interface:
Connect a PC to the unit's COM port as shown in Figure 3-16. Maximum recommended cable

length is 50 ft/15 m.
Not all PCs include a serial port. If one is not available, the Orbit MCR's USB port can be used
NOTE
to access the device management console by using a Mini-USB cable between the device and a
PC. The PC needs to install the device driver.
NOTE
If the COM port has been configured for terminal server operation, pressing +++ switches it to
console (management) mode. Serial console mode is required for the following steps.
Launch a terminal communications program, such as HyperTerminal, with the following
communication parameters: 115200 bps (default speed), 8 bits, no parity, one stop bit (8N1) and
flow control disabled. Incorrect parameter settings are a frequent cause of connection difficulties.
Double check to be sure they are correct.
An adapter may be used to convert the unit's RJ-45 serial jack to a DB-9F type (GE MDS part no.
73-2434A12). If no serial port exist on the PC, a Mini-USB cable may be connected between the
MCR's USB device port and the PC.
