rameters correct for source/destination devices?
the serial cables terminated correctly? If a null-modem
ble is used, it must be placed at the receiver end.
en using RS-232 transmitters or receivers in daisy chains,
t5 switches, Cat5 distribution amps, or multi-output
nsmitters, the serial signal is a unidirectionally broadcast
ode only. In this mode, all other MultiView™ CAT5 Video
stem devices must be the simplex serial type.

s on Daisy Chaining:
n daisy chaining, the maximum cable distance is not increased
nd the rated distance of the receiver used. For example, an
00 can only daisy chain within 600 ft of the transmitter.
possible to daisy chain out of a short range receiver into a longer
e receiver to increase the range. For example, over 600 ft an
00 can be daisy chained into an AK1200 which allows for daisy
ning to 1,200 ft.
If using L/R summed audio, simplex serial, or SPDIF units a
maximum of 12 units may be daisy changed within the rated
cable length of the receiver.
When using SA units, a maximum of 4 units may be daisy
chained within the rated cable length of the receiver.
When using SAP units, a maximum of 12 units may be daisy
chained within the rated cable length of the receiver if using
standard cat5/6 or a maximum of 8 units may be daisy chained
within the rated cable length of the receiver if using skew-free
cable
