RS232 Serial Board

MTI part #81103, RS232 Serial Interface Adapter,
is used to adapt MTI data channels to an RS232
interface. The primary application for this device
is for serial interface to fire alarm equipment or
closed circuit television equipment. There are,
however, an unlimited number of applications for
the RS232 serial interface adapter.
The serial clock generator is located on the circuit
board. This clock generator generates clock rates
for baud rates of 300, 600, 1200, 2400, 4800, and
9600.
MTI data channel terminations are identical to the
standard MTI processor boards described under
part #81114 and #81035.MTI processor, part
#81034/S, is used for control of the serial interface adapter.
It should be noted that this is a standard MTI processor
which utilizes a Motorola MC68705C8 processor. The processor contains
all RAM and EPROM necessary for system operation.
The operating baud rate of the device is jumper selectable with the jumper
positions on the circuit
board. The RS232 connector is a standard 9 pin
D subminiature connector with standard pin out.
The connections for this unit are standard connections for a device termination.
