Purpose

Device properties

Monitor

Power Supply

The actual voltages provided by the power supply to various components.

Temp

Temperature in degrees centigrade measured at the CPU and at another position inside the case (Sys).

Serial <protocol>

Status

The current status of device.

Listening

Lit (green) when the device is operational and waiting for data to arrive.

Clear Counters

Resets all the counters at the bottom of the tab.

Bytes In

The number of bytes received by the device.

Bytes Out

The number of bytes transmitted by the device.

Activity

Lit yellow when data is being transmitted or received.

Comm port

The comm port and serial protocol to use for data transfer.

Bits per sec

The baud rate (speed) for data transfer.

Data bits

The number of data bits in each character. Baudot uses 5, true ASCII uses 7. We recommend using 8, as this can be used for any type of data.

Parity

Specifies that an extra bit is to be included in the data transmission. This can be used for error detection.

none

No parity bit is sent. Error detection is handled by the communication protocol.

even

The parity bit is set to 1 if the number of ones in the set of bits is odd, therefore making the number of ones even.

odd

The parity bit is set to 1 if the number of ones in the set of bits is even, therefore making the number of ones odd.

mark

Parity bit is always set to the mark signal condition (logical 1).

space

Parity bit is always set to the space signal condition.

Stop bits

Bits sent at the end of every character to signify the end of the character in the data transmission. Normally, 1 stop bit is used.

Rear mode

The operating mode for a data port that supports more than one mode. For example, RS-422 or RS-485.

BOOTP

Status

Lit green when the BOOTP server is running.

Lit red when the server has stopped.

Served

The number of IP addresses that the BOOTP server has allocated to devices on the network since the nControl unit was last booted.

Failed

The number of requests for IP addresses that were unfulfilled.

A failure can occur when all the IP addresses in the range have already been allocated and a further request for an IP address arrives.

The list of available IP addresses changes when addresses are allocated to devices and when addresses are reclaimed from devices when they are no longer required.

Message

A status message indicating that a task has been completed successfully, or that a problem has occurred.

Discovery

Status

Lit green when the SNMP discovery feature is enabled.

Lit red when the feature is disabled.

Count

The number of devices found during the last scan for devices on the network.

Refresh

Starts the discovery process.

Message

A status message indicating that a task has been completed successfully, or that a problem has occurred.

Net Ctl <protocol>

Status

The current status of the network control service.

Listening

Lit green when the service is operational and waiting for data to arrive.

Clear Counters

Resets all the counters at the bottom of the tab.

Bytes In

The number of bytes received by the service.

Bytes Out

The number of bytes transmitted by the service.

Commands

The number of commands that the service has received.

Errors

The number of commands that did not execute because they could not be parsed or failed when they were executed.

Redundancy

Active Host Information

Host Name

The name of the nTouch 180HD unit that is currently active. This will change to the name of the standby unit if it takes over.

This name is specified on the Network page of the web user interface.

Power Off

Powers down the unit.

Note: When you click this button, you will lose contact with the unit and no longer be able to control it until it has been switched back on and booted.

Failover

Switches control over to the standby unit. This is useful for testing the backup system once it has been configured, or manually switching over to the standby unit when the active unit has stopped functioning.

Standby Host Information

Host Name

The name of the standby unit.

Address

The IP address of the standby unit.

State

The status of the standby unit.

Last Sync

The date and time the standby unit last synchronized with the active unit.

Status

Lit (green) when NWare can contact the standby nTouch 180HD unit. If this LED is unlit, check that the redundancy settings on the Special tab of the nTouch 180HD web UI are correct.
