DEV 14-0087
The module is designed for ASI signal applications. Normally one of the two input
signals is routed to the three separately amplified output ports. In the case of
power loss, the primary input port ("In A") is routed only to the first output port
("Out 1") and the other output ports do not carry any signal.
The unused input port is terminated internally. Electronic switches and a failsafe
relay are used for switching.
Note:
 The DEV 14-0087 is the successor of the DEV 14-0001.

DEV 14-0088
The functionality of the module DEV 14-0088 is identical with the module
DEV 14-0087 (please refer to chapter 3.2.19), but the module is designed for
SD-SDI and HD-SDI signals in addition to ASI signals.
Note:
 Output port 1 ("Out 1") delivers an inverted ASI signal!
