(SAP) Option Module Settings
The SAP option module allows a bi-directional session to be established between a SAP-equipped transmitter
(MVII-DVI-Tx-SAP), and a specific SAP-equipped receiver even in a multiple-receiver daisy chain installation.
The SAP transmitter devices (MVII-DVI-Tx-SAP for example) do not have address DIP-switches. The factory-
default address of the transmitter is “0”.
The SAP receiver devices (MVII-DVI-Rx-1K-SAP for example) have address DIP-switches.
Each SAP-equipped receiver must have a unique address set first, via DIP-switch settings or by a serial
command entered directly at the receiver.
Once this has been done, a special
“set destination address” command is sent into the transmitter to specify
which receiver to open a session with.
If the transmitter is commanded to use destination address 0 (zero), serial data will be broadcast to all
receivers. This is the factory-default behavior.
To set the S
AP receiver’s address switches, you will need to open the
receiver
enclosure and set the DIP-
switches directly on the SAP module. The DIP-switch has 8 switches, one for each address bit position. Use
the SAP addressing chart provided on the next page to determine the proper switch addresses.
All receivers must have a unique address
. It is recommended to write the address on each receiver once this
step has been completed.
It is also recommended to keep a list of receiver addresses and locations to make it
easier to determine which receiver/display is desired to communicate with.
To set SAP address DIP-switches (at SAP-receiver units):
1. Remove the top cover assembly of the receiver.
2. Locate the 8 position dipswitch on the internal daughterboard assembly and using the SAP-addressing
chart, set the receiver address as needed.
3. Replace cover assembly and install unit.
Note:
It is also possible to set a SAP receiver’s address by a
serial-command
entered at the receiver itself. In
this case, simply ensure all DIP switches are set to address 0 (zero).
Please also refer to the
SAP II Programmer’s Guide
for additional information on SAP related settings and
operation.
