8.2.1.4 Protocoll-Select (CAUTION)
Controlling the interface (Protocol select)
CAUTION: THESE SETTINGS ARE VERY CRITICALLY!!
!S<DZ><#13>
Suppresses inter alia the output of data
DZ is the decimal value from the following binary listfor the different protocols.
Binary list of protocol parameters for DZ.
DZ (binary) =
xxxxxx00b (bit 1+2) : RS232 - MWS sends a datastring each second
xxxxxx01b (bit 1+2) : RS422 - MWS sends a datastring each second
xxxxxx10b (bit 1+2) : RS485 - MWS is addressed and sends data only on request
xxxxxx11b (bit 1+2) : Reserved
xxxxx1xxb (bit3) : MWS sends data only on request (RS232 + RS422)
xxxx1xxxb (bit4) : MWS sends data on request and when storing into the logger
xxxXxxxxb (bit5) : Reserved
xxXxxxxxb (bit6) : Reserved
x1xxxxxxb (bit7) : Sends check byte(bit 1+2
≠
11), simple XOR or CRC-8 (Bit21=1)
1xxxxxxxb (bit8) : Flash write protection. (Commands changing the data flash are
rejected (except update))
This mode only can be cancelled in SECURE-Mode!
xxxxxxxx 1xxxxxxx xxxxxxxxb (bit16)
: Suppresses reset outputs on the GPS / RS-232 port, which are
sent by default since V3.0222
xxxxxxx1 xxxxxxxx xxxxxxxxb (bit17)
: Standard protocol: Sets RS-485 full duplex to suppress the
waiting time in "normal" RS-485 mode (half duplex) (since V3.0240)
xxxxxx1x xxxxxxxx xxxxxxxxb (bit18)
: Prevents the port from disabling (since V3.0244)
Imortant when operating at a MOBOTIX cam!
xx1xxxxx xxxxxxxx xxxxxxxxb (bit22)
: MWS 5MV compatibility mode (data each 2 seconds)
By adding of single binary values the parameters can be combined.
Example for MWS with RS422 only sends on request:
for RS422 (binary) = xxxxxx01 (DZ=1)
for sending on request (binary) = xxxxx1xx (DZ=4)
added --> = xxxxx101 --> decimal = 5 --> !S5<#10>
CAUTION: With RS485 the WSA's address must always follow on ! or ?, for otherwise the com-
mand won't be recognized! (Standard@ = 10)
!S+<Bit#><#13> ;
Set single bit in protocol select
!S-<Bit#><#13> ;
Set back single bit in protocol select
Example: !S+3 activates sending data on request and when storing.
CAUTION! Never use this command with analog display connected!!!
