CRS-170A L-Band 1:1 Redundancy Switch MN/CRS170A.IOM

Modem and Switch Configuration Revision 13

4–12

Because the modem automatically detects if it is connected to a 1:1 redundancy system, the

steps required to configure both modems are minimal. Modem configuration, monitor and

control are possible through local or remote means (Figure 4-2):

• Local Control – Use the modem front panel to fully configure, monitor, and control the

modem operation:

o The LEDs indicate, in a summary fashion, the status of the modem.

o The VFD (Vacuum fluorescent Display) is an active display showing two lines of 24

characters each. It produces a blue light with adjustable brightness. Nested menus

display all available options and prompt you to carry out a required action.

o The keypad comprises six individual keyswitches. The keys have a positive ‘click’ action

that provides tactile feedback. Enter data via the keypad. Data, prompts, and messages

are displayed on the VFD.

• Serial Remote Control – Configuration, monitoring and control of redundant systems is

possible via remote means over an RS-485 multi-drop bus using Windows Command-Line,

where data is transmitted in asynchronous serial form using ASCII characters.

• Ethernet Remote Control – Configuration, monitoring and control of redundant systems is

possible via remote means over an Ethernet connection using the Telnet Command Line

Interface (CLI) or the CDM-570L/A HTTP (Web Server) Interface.
