using known ID 101 102 103 104
Note: ICU system address ranges between 01 to 04. ICU address 00 is reserved
for system configuration and should not be used.
2.8.3.2. Configuring the Number of BEAMER® Arrays
The 'save system features' command is used to configure the number of connected
BEAMER® arrays. Use this command to add or remove an array (logically) from the
system. To set the number of installed arrays to 2, use:
Code 10 (save system features), ICU address, 02, 00 (BEAMER® )
Note: Issuing the 'save system features' command will erase the previous
BEAMER® configuration. Previous definitions of arrays and Bias-T assignments
must be reprogrammed, following this command.
2.8.3.3. Bias-T Definitions
Once the arrays are configured, a Bias-T must be assigned for each array. 'Save Bias-T configuration'
command (code 14) is used for assigning the Bias-T for the arrays. For example, the following
command assigns Bias-T #1, 2, and 3 to array #1:
Code 14 (save Bias-T configuration), ICU address, 01 (array address), 07 00 (Bias-T #1,2,3 assigned)
Bias-T addresses and Bias-T physical locations are the same (i.e. Bias-T number 1 is mapped to Bias-
T address 1, and so forth).
Note: Bias-T assignment is bit-wise representation of the command data bytes. Also note that the
above command does not configure the Bias-T type (Tx or Rx). Repeat for every installed array in the
system.
2.8.3.4. Configuring the Bias-T Type
Using the command 'save Bias-T type' (code 16) will define the Bias-T type for the ICU (note that this
logical definition must agree with the actual, physical Bias-T type, as installed at the ICU. For ICU,
this is always Rx-Rx-Tx-Rx-Rx-Tx-Rx-Rx-T- right to left, form the rear). This logical definition does
not change for the ICU.
The following example defines ICU Bias-T installation:
Code 16 (save Bias-T type), ICU address, 01 01 02 01 01 02 01 01 02 01 01 02 02
Note: For Bias-Ts not installed, thus will appear as 00.
2.8.4. Setting the Bias-T Attenuation
Bias-T attenuation, for either Rx or Tx Bias-T, can be modified with the command 'save Bias-T
attenuation' (code 18). Command 'read Bias-T attenuation' (code 19) can read these settings.
