Printronix Integrated Network Interface Card Ant. Diversity, Preamble, Power Mgmt, Transmit Power

Wireless NIC Configuration Using The Control Panel

•Channel

This is the frequency used for wireless communication. The 2.4GHz band spectrum is divided into different channels (1-15). It is set to "Default" so that the NIC can detect the correct channel to communicate with the Access Point in infrastructure mode. If the operation mode is "Ad Hoc" and the channel is known, the user can set the corresponding channel in this menu.

NOTE: This parameter is not applicable for 802.11g/b.

•Ant. Diversity

This is used to select the antenna for communication. It is recommended to set to "Primary" for the NIC to detect for optimal communication. It can also be set to "Diverse" or "Auxiliary".

•Preamble

This is the preamble used in the wireless packets. It is recommended to set to "Default" so that the NIC can detect the correct preamble. The preamble is approximately 8 bytes of the packet header generated by the AP is and attached to the packet prior to transmission. The preamble length is transmission data rate dependent. The "short" preamble is 50% shorter than the "long" preamble. Transmit power is 0–100%. It must match the Access Point's preamble configuration.

NOTE: This parameter is not applicable for 802.11g/b.

•Power Mgmt

This option allows you to set power-save mode and sleep time. A value specifying the sleep time in milliseconds will be provided. If set to zero, power-save mode will be disabled. It is recommended not to change this setting.

•Transmit Power

This option allows you to specify the power level used by the wireless card to send network packets to the access point. Transmit power is specified as a percentage of full pwer (0 – 100%).

•Internat. Mode

When enabled, the Wireless option adapts to international frequency requirements in Europe.
