10 ICE-HE Ethernet Head End
Command Description
Commands shown in ASCII and end with carriage return
(Decimal 13, Hex $0D, or Enter key).
Response displays * character to signify end of characters, or time out if no characters are received
after 2 seconds.
Tip: Just hit Enter to repeat any Terminal command, ESC to clear or cancel current command
Echo Enable EN Enables character echo so you can see typed characters on screen. Or use the Terminal settings to
Local Echo.
Echo Disable EF Disables terminal character display (default).
Version VE
ID
IB Displays HE software version
Displays HE software version
Displays HE boot loader software version
Reset Z! Performs system reset.
Show Devices
SD Displays list of 2-way devices stored in HE memory. List can be created by iC Commander software,
ABC-MRC software, or Scan and Build command below.
Example Response: Devs Present:
257-261
263
265-271*
Show Missing SM Displays list of missing 2-way devices (compared to HE memory list).
Example Response: Devs Missing:
262 -263
264*
Show Present SP Displays number of present devices and number of devices expected.
Example Response: Num Devs Present : 1
Num Devs Expected : 53*
Show Numbers SN Displays number of present devices and number of devices expected.
Example Response: SN 0001/0053*
Scan and Show SZ Scans iC-Net and displays list of all 2-way devices found (does not change HE memory).
Scan and Build Z^ Scans iC-Net and saves list of all 2-way devices found into HE memory.
Show Log L Returns four hex bytes, separated by commas. If any of the bytes change as you repeat the
command, there is likely an error in return communication from iC-Net devices.
Clear Log DL Clears the L hex bytes to zero.
RF Receive Level AR Level RF Received (idle) background level, no units constantly transmitting
Example Responses:
AR RRRR/SSSS = Receive/Sensitivity levels
AR 0321/1337 = 0.321V “quiet” receive level, 1.337V high threshold
AR 0321/0693 = 0.321V “quiet” receive level, 0.693V low threshold
AR 2250/0693 = 2.251V constant transmit receive level, 0.693V low threshold
This command is used to check RF levels at 5.6MHz, compared to the current sensitivity level
setting (DIP Switch 1, page 4). Test the RF receive level a few times when the iC-Net units are not
transmitting, then again when one iC-Net unit is set to constantly transmit. The Sensitivity level
should fall about halfway between quiet and constant transmit RF levels.
RF Output AO Displays RF output level
Example Response: AO 5000* (Full Output)
DIP Setting AS Displays DIP switch setting in binary format
Example Response: AS 222* (Switches 1 and 6 off)
