13. Timing parameters PTCs that use the power saving protocol suspend the activity of all internal power consuming devices in duding its radio receiver to extend battery life The PTC powers up momentarily and transmits a poll to the access point in order to fetch any packets the ac cess point has for it There are a number of timing pa rameters that determine when the PTC polls the access point for data packets One of these parame ters the fast poll delay is critical to PTC perform ance The fast poll delay parameter determines how soon a poll is sent following a successful transmission It is the most critical timing parameter for AirVu TN 3270 and AirVu TN 5250 systems because an ARP re quest from another station must be answered quickly with an ARP response Therefore the fast poll delay parameter should be set to zero or a very low value so that the PTC can poll and pick up the ARP response before it times out and goes into the power saving mode Other poll timing parameters determine the fre quency of polls that follow the first poll The default values of these parameters are effective in virtually every case and do not need to change Aesthetic parameters Aesthetic parameters deal with the PTCs display backlight cursor and so on These parameters can be set to your preference and have little effect on data flow in the system Barcode scanner wand parameters Barcode scanners are not built in to every PTC capa
