9 Relays
The side of the relay marked with a bar correspondents to the
side marked with a "1" on the silkscreen. In contrast to the IC
marking the notches have no meaning!
10 4mm Binding Posts
Use a large soldering iron tip and plenty of solder for the
binding posts, as they need a lot of heat to solder. If your
soldering iron's temperature is adjustable, set the temperature
20 – 30° higher than normal. Try to heat the binding posts, not
the pcb, as too much heat may damage the tracks.
11 SUB-D9 Connector (RS232 Model only)
Mount the connector on the back plate of the case. Solder a
wire from pin 2 to the "TX" pad and from Pin 5 to the "GND"
pad on the board.
