3.2 Command Line Operation

Command line interface is performed through RS-232 or Ethernet.

The commands are coded in ASCII and HEXA. All descriptions are shown in Table 3.1. A
command line consists of string of ASCII or HEXA codes in series as shown below;
Start (1 Byte) + Router ID (3 Bytes) + Command (1 Byte)
+ Data Length (3 Bytes)
+ Output Number (2 Bytes) + Input Number (2 Bytes)
+ Output Number (2 Bytes) + Input Number (2 Bytes) +
…..
+ End (1 Byte)

A command line allows execution of only one command. Multiple commands require ex-
ecution of multiple strings; one command per string.

All strings begin with Start byte.

Router ID can be selected within the range of 000 to 255; written in 3 bytes. (Default
factory setting is 255. Refer to Chap. 2.1.)

Data Length represents total number of all bytes. Data Length is determined by the
number of channels in the command line.

For example: Configuring 4 Input-Output connections (8 channels), data
length is 016 in ASCII - 16 bytes in base of 2 bytes per channel regardless of
Input and Output.

Input channel Number follows Output channel Number - designated as a pair.

A command line closes with End byte.
