Switch settings - AV204T/AV208T only
The AdderLink AV204T and AV208T transmitter modules are both equipped
with 10-way mini switches to allow quick configuration of various items. For
normaloperationinthemajorityofcases,allswitchesshouldbeOFF.
Switch 1 is used when upgrading the internal firmware and switches 2 to 10 are
all related to various aspects of serial communications.
Note: All switch settings must be selected before power is applied.
