Arbiter
Arbiter sells a range of global positioning system satellite clock receivers. This driver supports model 1084, model 1088, model 1092 and model 1093. To operate these units with the PresenTense Time Server NTP4 plug-in, turn off the daylight savings time feature using the D0 command and turn on initiate UTC broadcasts using the BU command. The NTP4 plug-in initiates communication with the clock by sending a time quality query ( TQ ). Once an echo reply including the time quality character has been received from the clock, the NTP4 plug-in turns on pulse per second timestamps by sending a B5 command to the clock. The Arbiter clock in turn responds by broadcasting a "format b5" time indication once every second.
