Host-side RS-422 settings usually also include Data Bits, Stop Bits and Handshaking/Flow Control parameters.

When setting up the Host RS-422 port, use the following additional settings:

 8 Data Bits

 1 Stop Bit

 No Handshake/Flow Control

DUAL OUTPUT MODE COMMAND 4.3.2

This command enables and disables Dual Output Mode described in Section 2.2. By default, VIPER™ emits

command responses and data to the I/O port from which the command was received. This includes streaming

P&O data. When Dual Output Mode is enabled, P&O data is output to both USB and RS-422 ports. Command

responses are also output to both ports.

In VIPER™ Command Manager, Dual

Output Mode is configured in the SEU

Block Config panel in the I/O Config

group.

Access the SEU Block Config panel by

selecting to the right of the VIPER™

SEU icon in the Edit Mode Status

Pane.

Default: Disabled

Scope: SEU

Persistent: NO

TIP OFFSET COMMAND 4.3.3

The TIP OFFSET of a VIPER™ Stylus is the positional offset of the Stylus tip from the electromagnetic (EM) center

of the Sensor coil inside the Stylus handle. Each VIPER™ Stylus is factory calibrated with a tip offset. This allows

the tip of the Stylus pen to act as the measurement reference.

For all other VIPER™ Sensor components, there is no factory calibrated tip offset.

For Stylus and Sensor components, the TIP OFFSET values cause VIPER™ to produce P&O for a point other than

the electromagnetic (EM) center of the Sensor coil.

Applying the TIP OFFSET command to a Stylus overrides the factory calibrated offset that is read by VIPER™ when

the SEU is started. In most circumstances it is not recommended to apply this command to a Stylus.

Note: Applying the TIP OFFSET command to a Stylus overrides the factory

calibrated offset that is read by VIPER™ when the SEU is started. In most

circumstances it is not recommended to apply this command to a Stylus.

TIP OFFSET may be useful for a Sensor when the Sensor is mounted on a custom instrument, where the Position

of the tip of the instrument is of interest rather than the Sensor itself.
