Host Interface
The evaluation board supports RS-232 serial, TTL serial interfaces with hardware flow control and parallel
interfaces.
Serial/Parallel Interface Select
Two multi-pin jumper blocks select either serial or parallel interface mode. The position of SELECTOR 1 and
SELECTOR 2 determine the operating mode. Intsall jumpers in the serial position for serial operation (default) or
parallel position for parallel operation.
Note: Be sure to use the 8 position jumper plugs provided with the board to set the host interface mode or, if
individual jumpers are used, that ALL jumpers are in either the SERIAL or PARALLEL modes.
SERIAL MODE INDICATOR (D7) will light when both jumpers are in the serial mode position.
To select the digital interfaces (serial or parallel) remove the RS-232 serial interface jumpers. This disconnects the
RS-232 interface and drivers.
The module signals are connected directly to either the TTL serial interface (SERIAL I/F) or the TTL parallel
interface (PARALLEL I/F) depending on the position of selector 1 and 2. Both Selectors 1 & 2 must be set to the
either serial or parallel mode.
There are no buffers or drivers between the Socket Module and the evaluation board connectors. This provides the
user direct electrical access to all the signals on the Socket Module.
RS-232 Interface
The user can select the RS-232 by installing the RS-232 Select Jumpers on JP3 (Labeled ‘SERIAL I/F SELECT’
on Rev 1 of the PCB). This connects the socket module serial interface signals to the on-board RS-232 interface.
The output of the RS-232 interface IC connects to the DB-9F connector. The RS-232 interface is fully voltage
compliant and is configured as DCE (Data Communication Equipment).
Note: The RS-232 and digital serial interfaces can not be used at the same time.
