Hardware Configuration
Overview
Both the SkyePlus MXH and the SkyePlus MXU are designed to connect to the
SkyeModule reader via the SkyeTek host interface board for all power, control,
and RF connections (see “Connecting to the Host Interface Board” below).
● You can also create a custom interface for the SkyePlus multiplexer without
using the host interface board by running the multiplexer connections
through either the CF-style or MH-style connectors. (See ‘‘Connecting
Through the MH Module Connector’’ on page 23 or ‘‘Connecting Through
the CF Module Connector’’ on page 24.)
● If you have an older firmware release and are using a Common Blade
Interface Board (CBIB) to connect your multiplexer to your reader, refer to
Appendix C, “Using SkyePlus Multiplexers wi
th a CBIB” on page 41.
● If you have a SkyeModule M1, refer to Appendix D, “Using a SkyePlus
MXH with a SkyeModule M1” on page 45.
Connecting to the Host Interface Board
● Figure 3-1 on page 22 shows the physical connections for the multiplexer
I/O and antenna cables host interface board.
● Table 3-1 lists the pin connections used by the 7-pin cable (provided with
your multiplexer) to connect the multiplexer to the host interface board.
