Operation Manual

0E Power Control options (continued)
b1: Ignition delay 0: 1 sec 1: 5 sec
delay after IgnMon (pin 15) returns to a high level, before
normal operation resumes
b0: reserved for future - leave set at 0
Programmable Parameter Summary (continued)
10 J1850 voltage settling time
setting (in msec) = (PP 10 value) x 4.096

00 to FFActivity Monitor options
Each bit controls an option, as follows:
b7: monitor master control 0: disabled 1: enabled
must be 1 to allow b3 to b6
b6: allow wake from Low Power 0: no 1: yes
wakes on shift from no activity to activity
b5: Auto LP control 0: disabled 1: enabled
allows low power mode if the OBD activity stops
b4: Auto LP timeout 0: 30 secs 1: 150 secs
no OBD activity timeout setting
b3: Auto LP warning 0: disabled 1: enabled
if enabled, says ‘ACT ALERT’ on timeout
b2: reserved for future - leave set at 1
b1: add exclamation mark 0: no 1: yes
if 1, sends ‘!’ before ACT ALERT and LP ALERT
b0: LP LED 0: disabled 1: enabled
if 1, the OBD Tx LED flashes when in Low Power mode
(one 16 msec flash repeated every 4 seconds)
