Serial Remote Control MN/PCB4000.IOM

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
aupported in both EIA‐232 and EIA‐485 applications.
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 three virtual commands can be used to program the individual SSPAs when in Phase Combined mode (RED=1):
• CAA= • DAT= • TIM=
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= • ART=
5.2.2.4 Address Delimiter
This is the “forward slash” character '/' (ASCII code 47).
