3-14 Verifying Serial Port Connections

LX Series Configuration Guide

X To validate cable configurations:

Execute the following command to test the connection:

Example InReach:0 >>test port async <port_number> [width

<number>] [lines <number>] [loopback]

There are several ways to execute the command

1. Test the port async port:

Example InReach:0 >>test port async 4

This option generates 23 lines of 80 characters each of a

printable sequence of ASCII characters to be sent to the

destination port. The general rules are:

• The access of the destination port must be Local,

Remote, or Dynamic.

• The destination port must be in an idle state with no

subscriber active (an exception to this rule is when the

source and the destination ports are the same).

• Only one port can be specified.

• If a CTRL-C is issued during the test, the test is stopped

after a delay period and the bytes generated up to that

point are counted.

• An end of test message is displayed in all cases.

2. Test the port async port, but limit the width of characters

returned:

Example InReach:0 >>test port async 4 width 50

This option generates 23 lines of 50 characters each of a

printable sequence of ASCII characters to be sent to the

destination port. You can enter values from 1-132. The

default is 80. An end of test message is displayed.

3. Test the port async port and limit the width of characters

and lines returned:

Example InReach:0 >>test port async 4 width 50 lines 15

1 2 ... 100 101 102 103 104 105 106 107 108 109 110 ... 691 692
