J5 Attn. line from D9-connector to BS2 open to use D9 for serial coms to BS2 link to program BS2 J6,7 Grip/lift, Auxilliary and Ultrasonic Servo-supply see photograph 2 for link placement left pins - Servo-supply - switched off by SW1 right pins - Servo-supply - unswitched - always ON J8 BOS commands, serial-coms baud rate from BS2 or D9 open 2400 linked 9600 J9 BS2 controls the switched 5v electronics supply 'epcon' to 'epower' J10 sets the switched 5v electronics supply to ON 'epower' to 'ON' for when the BOS is being controlled from a terminal J11 link to supply Protected 7v to Expansion-connector pin12 J12 BS2 reset, link to reset BS2, Allows the BS2sx to be held in reset when the BOS is controlled from a terminal. See J1-4. Reset signal also appears on Expansion-connector pin1 J13,13,15,16,18b,19 ------------------- allow the Expansion-connector lines to be used for something else when daughter boards are used.
