Campbell Hausfeld SDM-SIO4 사용자 설명서

Section 4.  Programming the SDM-SIO4

because they are compiled.

This command exits the command line and returns port 1 of the SDM-SIO4 to
normal operation.

This returns the internal EPROM part number, signature and the string signature if
good or 0 if bad. This will give the same signature as Campbell Scientific’s
SIG.COM PC program.

This sets up the port 1..4 to the communication format you require.

‘port #’ means the port number (1..4) to set up. For details of the other parameters
(baud #...delay) see Appendix B.

The SDM-SIO4 is set to a known default state. All strings, filters and formatters
are erased, ports are set to 9600 baud, 1 stop bit, no parity and no handshake. All
transmit and receive buffers are flushed. All error counts are zeroed.

The system RAM is tested and the SDM-SIO4 is then reset. The string ‘

’ is returned if the RAM is OK or ‘

’ if some part of the

memory failed.

This command changes the port for which the command line is available. This
command line port setting will stay in effect for further sessions until a new port is
chosen or power is removed and then re-applied, in which case the command line
reverts to port 1.

This outputs the general status of the SDM-SIO4. The results are as follows:

If the value is 0 the battery needs replacing.

If the value is 1 the battery is good.

This is the current SDM-SIO4 hardware address.
