ATLAS 800 Series System Manual Dual Video Option Module
Test
0 Inh Write security: 3; Read security: 5
When the port detects an uninterrupted string of 0s being transmitted for more
than one second, setting this parameter to On will cause the ATLAS 800 Series
to send 1s toward the network.
Test
Write security: 5; Read security: 5
These options initiate different types of tests and display test results.
Prt Write security: 5; Read security: 5
Indicates the port number.
Loopback Write security: 4; Read security: 5
The Video Module supports both local and remote loopbacks. The following
options are available:
Loopback Status Write security: 5; Read security: 5
This read-only option indicates a port’s current loopback status by displaying
any of the following status messages:
No Loopback Active
Looping Up Remote Unit
Remote Unit Looped Back
Looping Down Remote Unit
Remote Loop-Up Failed
Port Looped From Remote Source
Port Loopback Active
511 Write security: 4; Read security: 5
Controls the activation of the 511 test pattern generator and detector. The 511
pattern is generated inward through the ATLAS system.
Options Description
No Loopback
No active loopback.
Local Loopback
Activates both a local loopback (back toward the DTE) and a port loopback
(toward the network).
Remote Loopback
Initiates a local loopback request sent to the remote Video Module. This allows
for end-to-end circuit test.
The REMOTE LOOPBACK option is only supported for Dual Video
Module to Dual Video Module applications.
