© Copyright WhereNet, Corp. 2008 WhereNet Confidential
A WherePort IV set to 0º phase is defined as the master and all the other WherePort IVs are then
connected to it using the phase wire connections. Phased WherePort IVs must all have the same ID.
Figure 14 Phase and WherePort IV Orientation
7.6. Sequencing
WherePort IVs that have been connected electronically can also operate in the sequence mode.
Sequenced WherePort IVs do not transmit at the same time. The first WherePort IV sends its message
and then shuts off its field while the next WherePort IV in the sequence sends its message. The number
of times each WherePort IV sends its message is set using the CMCn command. The number of
WherePort IVs in the chain is set using the CMWn command. See Figure 15 through Figure 57.
The master WherePort IV LED in a group of sequenced WherePort IVs is green when active. The
slave WherePort IV LEDs are yellow when they are active. The LEDs are all off when the WherePort
IVs are not active.
