- location AK-WB1 ???
200-218-010
- 4-2-09 : ran bench test for 1.5 hrs with 217-010
ECOs
BATTERY ECO
Enables measurement of the battery voltage without an external battery data cable.
- solder ball / zero ohm resistor across R222 and R233
MILE ECO
Allows the EC30-MILE encoder to be connected to MC, increases output clock voltage.
- Disconnect pin6 of D10 from the signal Hall.C;
- On J10 (5pin x 1.25mm header) install a 4.7k 0603 resistor between pin 4 (5VDMC) and pin 3 (HALL_C).
- Replace R86 with a 220 ohm 0402
pinout
- 1 GND
- 2 VCC (5)
- 3 N-
- 4 N+
- 5 B-
- 6 B+
- 7 A-
- 8 A+
- 9 GND
- 10 VCC
- 11 SSI-DAT (to HALL.A)
- 12 SSI-CLK (to HALL.C)
LIFEFIX ECO
Increases cutoff frequency of the analog temperature measurement signal. The 'battery temperature' signal represents the loadwasher force.
- replace C73 w/10nF, 0402 NPO
- replace R102 w/2.0K, 1%, 0402
rev 300 mods for DIGITAL SSI interface on EXT
These ECO permits the connection of an RMB20SC, or CB's AKENCx PCAs AKENC
- EXT_AN0 - modify for high speed digital input to MC
- replace R207 w/1k (1% resistor)
- replace C135 with a 1.6K (1%) resistor
- EXT_AN1 - (use as analog input) - disconnect AA HALL SENSOR
- remove R94
- ANALOG_EXTPWR - switch to 5V
- remove R226 and R228 (if installed)
- short R227 (w/0 ohm 0402 or solder ball)
- HALL_B signal requires no change (goes to MC via 1k)
pinout
* J8 / AKENC3d * 1 (gnd) -> P1 (gnd) * 3 (+5) -> P2 (+5) * 4 (an0) -> P5 (an0 - P24.MISO) * 6 (hallb) -> P6 (dig0 - MC.SPI_CLK)
RMB20SC (highest resolution) connection
- SC J8.1 (GND) to RMB20 GND
- SC J8.3 (EXTPWR) to RMB20 Vdd
- SC J8.4 (EXT AN0) to RMB20 DATA+
- SC J8.6 (HALL_B) to RMB20 CLOCK+
- RMB20SC has differential driver IC "LB197Q" that would require biasing to receive CMOS logic. Thus remove this IC from the RMB20 and attach directly to the IC pads.
rev 300 mods for LINEAR OUTPUT RMB20 -V interface
This ECO permits analog output RMB20 to be used.
- EXT_AN1 - disconnect AA HALL SENSOR
- remove R94
- ANALOG_EXTPWR - switch to 5V
- remove R226 and R228 (if installed)
- short R227 (w/0 ohm 0402 or solder ball)
RMB20V (any -V will work, 45 or 90deg is best) connection
- SC J8.1 (GND) to RMB20 GND
- SC J8.3 (EXTPWR) to RMB20 Vdd
- SC J8.5 (EXT AN1) to RMB20 Vout
