Chapter 9. SERIAL-BASED REMOTE PRODUCT
MANAGEMENT
9.1 Introduction
The serial remote product management interface is an electrical interface that is either an EIA-485 multi-drop bus (for the control of
many devices) or an EIA-232 connection (for the control of a single device). Data is transmitted in asynchronous serial form, using ASCII
characters. Control and status information is transmitted in packets of variable length, in accordance with the structure and protocol
defined in later sections.
1. To proceed with Serial-based Remote Product Management, assumptions are made that:
• The CRS-500 and its Redundant and Traffic Modems are interconnected and are operating with the latest version firmware
files.
• A user-supplied, Windows-based PC is connected to the CRS-500 as follows:
o
The user PC serial port is connected with a user-supplied serial cable to the ‘P1 | Remote Control’ DB-9M port located
on the CSU rear panel CRS-530 System Controller Module.
o
The user PC Ethernet port is connected via a user-supplied hub, switch, or direct Ethernet CAT5 cable connection to
the CRS-500.
o
The user PC is running a terminal emulation program (for operation of the CRS-500 Serial or Telnet Interface) and a
compatible Web browser (for operation of the CRS-500 Web Server Interface).
