4.2 Serial Connections
Serial protocol provides a classic connection to the MOS-AL162F. The Communication/Power Cable is
most commonly used for this set up as it provides connections for DB9 serial and floppy power cables.
To place your board in Serial mode, adhere to the steps laid out below.
1. Set the Baud Rate jumper.
9600bps: Place a Jumper on the GPO Header before the unit is powered up.
19200bps: Pulled up as default.
2. Set the Protocol Select jumpers.
RS232: Connect the three jumpers*in the 232 protocol box with the zero ohm jumper resistors
provided or an alternate wire or solder solution.
TTL: Connect the two jumpers* in the TTL protocol box.
*Note
: Jumpers must be removed from all protocol boxes save for the one in use.
3. Make the connections.
a. Connect the four pin female header of the Communication/Power Cable to the
Communication/Power Header of your MOS-AL162F.
b. Insert the male end of your serial cable to the corresponding DB9 header of the
Communication/Power Cable and the mate the female connector with the desired
communication port of your computer.
c.
Select an unmodified floppy cable from a PC power supply and connect it to the power header
of the Communication/Power Cable.
4. Create.
