LBC-4000 L-Band Up/Down Converter System
Serial-based Remote Product Management
6.2.2.2

Target Address

Up to 9,999 devices can be uniquely addressed; in EIA‐485 applications, the permissible range of values is 1 to 9999. The address is
programmed into a Target unit using the remote control port.
Each block converter module has its own address:
Module
LBC-4000
Block Converter A
Block Converter B
If several devices share an EIA‐485 bus, it must be noted that the LBC‐4000 will require three addresses, and should be spaced apart
accordingly.
The Controller sends a packet with the address of a Target – the destination of the packet. When the Target responds,
the address used is the same address, to indicate to the Controller the source of the packet. The Controller does not
have its own address.
6.2.2.3

Address Delimiter

This is the "forward slash" character '/ ' (ASCII code 47).
6.2.2.4

Instruction Code

This is a three‐character alphabetic sequence that identifies the message subject.
Wherever possible, the instruction codes have been chosen to have some significance – e.g., FRE for Operating FREquency, IPA for
Management IP Address, etc. This aids in the readability of the message, should it be displayed in its raw ASCII form.
Upper case and lower case alphabetic characters may be used ('A' to 'Z' and 'a' to 'z', ASCII codes 65‐90 and 97‐172).
