5.2.2.2 Target (Base) Address; 5.2.2.3 Virtual Address - Comtech EF Data PCB-4000A Installation And Operation Manual

5.2.2.2 Target (Base) Address

Up to 9,999 devices can be uniquely addressed. In the EIA-232 application, the permissible range of values is 1 to 9999. It is programmed
into a Target unit using serial remote control. The factory default target address is 1.
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.

5.2.2.3 Virtual Address

Virtual Address is a method that allows the user to access the SSPA via the PCCB using any communications software. Virtual Address is
supported in the EIA-232 application.
The following example depicts use of the virtual addressing scheme:
<123V1/MUT? where:
Base address = 123;
'V' = virtual address delimiter;
1 = virtual address of SSPA automatically set by the PCCB.
Notes:
1. Only four virtual commands can be used to program the individual SSPAs when in Phase Combined mode (RED=1):
•
CAA=
•
DAT=
•
TIM=
•
IAP=
2. All virtual queries can be directed to the individual SSPAs in any mode.
3. The following virtual commands can NEVER be used to program the individual SSPAs:
•
MUT=
•
ATT=
