Serial Interface (SIO) Mezzanine
The Serial Interface (SIO) mezzanine is optional. If purchased with the
System Controller the mezzanine will come installed. If the mezzanine is
purchased separately installation consists of plugging the mezzanine into
the Controller module and securing it with the provided standoff screws.
The SIO ISA BOARD mezzanine provides serial interfaces for eight ports at RS-
422/485. Four of the eight ports will also support RS-232. User adjustments
are available for each port.
SIO ISA Mezzanine Settings
Eight RJ-45 ports are controlled by the SIO ISA mezzanine. The ports are
labelled 0 to 7 on the mezzanine. See Table 3 for port assignments and
signal types. Each port has a Duplex Jumper, which allows you to choose
Half or Full Duplex. The default setting is
Full; if you want to use the Half
setting you must also change the DIP switch setting.
The DIP switch bank has four switches. DIP switches 1 and 2 must be in the
On (default) position to terminate the bus. DIP switches 3 and 4 (Off Full
Duplex is default position) are set to the
On position if the Half position is
selected for the Duplex Jumper.
CAUTION On all mezzanine ports (whether used or unused), DIP switches 1 and 2 must
be in the On position.
