Page 129: Chapter 6. Serial-Based Remote Product Management
Chapter 6. SERIAL-BASED REMOTE PRODUCT MANAGEMENT Introduction 1. To proceed with Serial‐based Remote Product Management, assumptions are made that: • The CRS‐311 and its modems are operating with their latest version firmware files. • The CRS‐311 is connected to a user‐supplied, Windows‐based PC, and: o The PC serial port is connected to the CRS‐311 rear panel CRS‐230 System Controller “REMOTE CONTROL” port using a user‐supplied serial cable. o The PC is running a terminal emulation program (for M&C of the CRS‐311 over its EIA‐232 or EIA‐485 Interface). 2. COMTECH EF DATA RECOMMENDS USE OF THE SERIAL‐BASED REMOTE PRODUCT MANAGEMENT INTERFACE FOR ADVANCED USERS ONLY. ALL OTHERS ARE STRONGLY ENCOURAGED TO USE THE CRS‐311 FRONT PANEL FOR MONITOR AND CONTROL (M&C) OF THE CRS‐311. SEE CHAPTER 5. FRONT PANEL OPERATION. The pinout table for the EIA-232/485 Interface connector is shown in Appendix B.1.3 Remote Control – DB-9M ...

CRS-311 1:1 Redundancy Switch Revision 7 Serial-based Remote Product Management MN/CRS311.IOM characters. Control and status information is transmitted in packets of variable length, in accordance with the structure and protocol defined in later sections. Interface Overview 6.2.1 EIA-485 For applications where multiple devices are to be monitored and controlled, a full‐duplex (4‐wire plus ground) EIA‐485 is preferred. Half‐duplex (2‐wire plus ground) EIA‐485 is possible, but is not preferred. In full‐duplex EIA‐485 communication, there are two separate, isolated, independent, differential‐mode twisted pairs, each handling serial data in different directions. It is assumed that a 'Controller' device (a PC or dumb terminal) transmits data in a broadcast mode via one of the pairs. Many 'Target' ...
Page 131: Basic Protocol
All bytes within a packet are printable ASCII characters, less than ASCII code 127. In this context, the Carriage Return and Line Feed characters are considered printable. All messages from Controller‐to‐Target require a response, with one exception: This will be either to return data that has been requested by the Controller, or to acknowledge reception of an instruction to change the configuration of the Target. The exception to this is when the Controller broadcasts a message (such as Set Time/Date) using Address 0, when the Target is set to EIA‐485 mode. 6.2.3.1 Rules for Remote Serial Communications with the CRS-311 1. Always wait for a response (or up to 15 seconds) from the CRS‐311 before sending the next query or command. 2. If a “time‐out” response (‘~’) is sent from the CRS‐311, you must resend the previous command. The ‘~’ response indicates that a pass‐through command to a modem/transceiver attached to the CRS‐311 has "timed‐out" and there was no response from the other device. During this wait, do not communicate with the CRS‐311. After the '~' response is ...
Page 132: Packet Structure
CRS-311 1:1 Redundancy Switch Revision 7 Serial-based Remote Product Management MN/CRS311.IOM • Status queries (no commands) are fast (typically less than 333 ms). • Configuration changes (commands) take longer and vary by modem type. • Individual command responses are faster than those to global commands (MGC). More parameters require more time. A pass‐through command is passed with little inspection by the Switch; remember that the modem being addressed may be at the distant end of an EDMAC link! Types of pass‐through commands: o To a local modem; o To a modem at the distant end (EDMAC); o To a local BUC or transceiver connected to a local modem; o To a distant end BUC or transceiver through the distant end modem. 6.2.4 Packet Structure The exchange of information is transmitted, Controller‐to‐Target and Target‐to‐Controller, in ‘packets’. Each packet contains a finite number of bytes consisting of printable ASCII characters, excluding ASCII code 127 (DELETE). ...

Page 134: Address Delimiter
CRS-311 1:1 Redundancy Switch Revision 7 Serial-based Remote Product Management MN/CRS311.IOM Note that, regardless of the Switch remote communications being configured for either EIA‐232 or EIA‐485 mode, the internal link between the Switch and the modems is always fixed at EIA‐232, 9600 baud, 8‐N‐1, address 0. The Controller sends a packet with the address of a Target ‐ the destination of the packet. When the Target responds, the address used is the same address, to indicate to the Controller the source of the packet. The Controller does not have its own address. 6.2.4.3 Address Delimiter This is the “forward slash” character '/ ' (ASCII code 47). 6.2.4.4 Instruction Code This three‐character alphabetic sequence identifies the message subject. Wherever possible, each instruction code is named to serve as a mnemonic for its intended operation – e.g., BKH for BacKup Holdoff time, or SID for Switch ID, etc. This aids in the readability of the message, should it be displayed in its raw ASCII form. Only upper case alphabetic characters may be used (‘A’ to ‘Z’, ASCII codes 65 ‐ 90). 6.2.4.5 Instruction Code Qualifier This is a single character that further qualifies the preceding instruction code. Code Qualifiers obey the following rules: 1. Controller‐to‐Target, the only permitted characters are: Character Definition This character is used as the Assignment Operator (AO). It establishes that the Instruction Code that precedes it is to be used as a (ASCII code 61) command to assign or configure operation.

Page 179: Appendix C. Addressing Scheme Information
Appendix C. ADDRESSING SCHEME INFORMATION Introduction to Addressing A CRS‐311 1:1 Redundancy Switch provides 1:1 modem redundancy; that is, it is capable of controlling one Traffic Modem and one Redundant Modem. You can remotely communicate to the Switch or either of the modems, using the appropriate addresses, via EIA‐232 or EIA‐485 using the DB‐9M “Remote Control” connector on the CRS‐230 System Controller module that is installed in the CRS‐311. • For Switch‐to‐modem communication using SLM‐5650/5650A modems: The Switch uses serial communication via the HD‐15 Control Cable that is connected between each TMI/RMI ...
Page 180: Switch Address
CRS-311 1:1 Redundancy Switch Revision 7 Appendix C MN/CRS311.IOM Switch Address The permitted Switch remote control addresses are limited: • For EIA‐485 connections, the only permitted addresses are 1000, 3000, 5000, and 7000. • For EIA‐232, the only permitted address is 0000. The Switch settings for external communications are totally independent from the internal communication between Switch and traffic modems. Modem and Transceiver Addresses To monitor and control modems and transceivers at the distant‐end of the communication link, EDMAC must be enabled, via the modem front panel, in Local Mode. Set the Tx and Rx ...
