for Firmware FE-SEAS Ver 1.1

Last update: 15 Mar 2001

Commands:

• all commands preceded by # and terminated with CR (ENTER)
• responses are terminated by CRLF
• Note: for power controlling commands, 0 = ON and 1 = OFF

C - Close inlet

• responds with 0
• Note: test with STAT command for completion

D - Detect water level in inlet funnel

• responds with a HEX-ASCII byte where bits are SET (1 = DETECTED) on detection, clear otherwise, as follows:
  • Bit 0 - 1st level detection
  • Bit 1 - 2nd level detection
  • ...etc...
  • Bit 7 - 8th level detection
• Note 1: With current hardware, only first 4 levels are used; 4 MSB's always 0
• Note 2: You should never see a higher level detect without ALL lower levels showing detect.

H - request HELP menu

K - Kill inlet motor power

• responds with 1
• Note: stops the motor immediately

M - Motor commands (direct control)

• MEN[=0,1] - request current status or power ON/OFF motor
  • eg: MEN=0 starts motor
  • returns current setting (i.e. 0 or 1) after request or set
• MDIR[=0,1] - request current status or set direction of motor
  • eg: MDIR=0 sets motor direction CW
  • returns current setting (i.e. 0 or 1) after request or set
• MLIM[0,1] - request current status of limit switch 0 or 1
  • eg: MLIM0 request limit switch 0 status (1 = activated, i.e. at limit = OPEN)
  • switch 0 indicates inlet OPEN status, switch 1 indicates inlet CLOSED status

O - Open inlet

• responds with 0
• Note: test with STAT command for completion

P - Pump commands

• P1[=0,1] - request current status or power ON/OFF on Pump 1
  • eg: P1=0 starts Pump 1
  • returns current setting (i.e. 0(= ON) or 1 (= OFF)) after request or set
• P2[=0,1] - request current status or power ON/OFF on Pump 2
  • eg: P2 requests current status (ON or OFF) of Pump 2
  • returns current setting (i.e. 0(= ON) or 1 (= OFF)) after request or set

STAT - request HEX status byte

• status bits:
  • bit 0 - Motor Direction - 1 = CW = closing
  • bit 1 - Motor Enable - 0 = ON
  • bit 2 - OPEN limit switch - 1 = activated (inlet OPEN)
  • bit 3 - CLOSED limit switch - 1 = activated (inlet CLOSED)
  • bit 4 - Pump 1 power - 0 = ON
  • bit 5 - Pump 2 power - 0 = ON
  • bit 6 - unused - always 0
  • bit 7 - unused - always 0

• Some useful status return values:
  • 31 - closing
  • 39 - closed
  • 3B - closed and motor enable OFF
  • 30 - opening
  • 34 - open
  • 36 - open and motor enable OFF

• Example: returns 32 - not closed or open; stopped midway by K command while closing

Revision history:

• Original Release - V1.0 (obsolete)
• 15 Mar 2001 - V1.1 (reverse 'C' and 'O' commands to reflect wiring; update STAT command)
