direction
1 When this line is high, the RS-3000 will indicate an Open Boat
failure Input
w/ pull-up
2 Along with pin 10, this line provides the RS-3000 with +5 VDC
power Input
power
3 Along with pin 11, this line provides the RS-3000 with digital
ground Input
power
4 Monitors the voltage output from the T3000 power supply
( 1 VDC = 1.5 VRMS ) Input
5 Alternative to T3000 Reset button (falling edge, not level
sensitive) Output
w/ pull-up
6 For future use, not implemented in software. Input
7 A control voltage from the RS-3000 used to set the output
amperage of the T3000 (see note
1 )
Output
8 Not connected N. A.
9 When this line is high, the RS-3000 will indicate an Over
Temperature failure Input
w/ pull-up
10 Along with pin 2, this line provides the RS-3000 with +5 VDC
power Input
power
11 Along with pin 3, this line provides the RS-3000 with digital
ground Input
power
12 This line provides the RS-3000 with +12 VDC power Input
power
13 A digital control voltage from the RS-3000 used to switch the
T3000 power supply output ON (w/ a digital low) or OFF (w/ a
digital high) Output
w/ pull-up
14 This line tells the RS-3000 how to interpret the T3000 data: as
series wired or parallel wired. Digital high = series, digital low =
parallel. Input
w/ pull-up
15 Monitors the amperage output of the T3000 ( 1 VDC = 100 Amps
RMS when parallel wired / 50 Amps RMS when series wired Input
Note
1 : 10 VDC = 600 AMPs parallel wired [or 300 AMPs series] and has a linear relationship down to zero except for a
small value range between zero volts and a small fraction of a volt where AMPs will remain at zero.
