MULTIBASE OPERATION. SYNCHRONISATION LINKS
When two or more WBS-202 bases have to be operated in the same physical environment,
time synchronization is needed to avoid mutual interactions in both multichannel and individual
operation modes.
Connection is made by using RJ11 to RJ11 leads, 6/4 pin type (telephone line leads). Pin out is
non inverted: pin1 to pin1, etc. Connect the SYNK OUT from the base considered Master to the SYNK
IN of the next base considered Slave, and so on. Synchro connection from the Master can be
verified on the Slave units by a double glitch on each of the register switches. That helps on cable
verification and maintenance.
Next diagram shows the connection example:
Maximum allowed lead length is about 50 meter. Consult us for extended length.
System operation is the same as depicted in the manual with the following considerations:
Start-up time is not immediate. Allow up to 5 minutes to consider that all the system is full
operative. Until this period of time, the system is not fully operative; some beltpacks can be noisy or
unstable. This initialization time occurs every time the system is switched on. Best results are
obtained when the beltpacks are switched on after this time.
