36 s Getting Started XP8400
When no pins on header J2 are connected, an actuation voltage must be
supplied by connecting a 24V power supply at sockets V+ and GND on
header H3.
The XP8400 relays require an actuation voltage of 24 V.
These relays will not work with J2 pins 23 connected.
Apply a voltage on header H3 only when header J2 is not
jumpered. Applying power to the board when J2 pins 12 or
23 are connected can damage the relay board and other
boards on the bus.
Setting Board Addresses
Jumpers on header J1 (along with PAL encoding) determine the boards
bus address. Figure 5-4 shows the jumper settings to set addresses 07.
