To Interconnect WGFMUs
If multiple WGFMUs have been installed, connect the WGFMUs by using the
following cable furnished with the WGFMU. See Figure 3-25.
• WGFMU Sync cable, 16493R-803, number of WGFMUs -1 ea.
Figure 3-25 WGFMU Module Connection Example, Four Modules
If multiple WGFMUs have been installed, connect the WGFMUs as shown in
Figure 3-25. This connection makes it possible to perform the synchronous output
by the multiple WGFMU channels. In this figure, the master WGFMU is the module
which outputs the reference signal and the slave WGFMUs are the modules which
follow to the reference signal.
Open the Sync In connector on the master WGFMU and the Sync Out connector on
the last slave WGFMU.
The Trig Out terminal must be connected to the trigger input terminal of the external
equipment to make the synchronized operation of it.
CAUTION Connect the Sync Out/In, and Trig Out terminals to the specified terminal properly.
Connecting to the other terminal may result in damage to the WGFMU.
NOTE The B1500A does not support the synchronized operation between SPGU and
WGFMU.
