7.6 External Serial Commands

7.6 External Serial Commands
Many of the mini-OPC functions and parameters may be controlled or
changed via remote RS232 commands from a user-supplied computer.
The commands listed below may be sent directly to the RS232 port on
the mini-OPC main board using the Serial-USB converter cable and DB9-
Cgrid adapter cable provided with the mini-OPC.
DO NOT use the commands below when communicating with the serial
port on the tablet computer running the UAV Reader connected to a mini-
OPC. Use the commands listed in the UAV Reader Software section of this
manual.
Be sure to set the "com_type" to RS232. THE RS232 SERIAL PORT ONLY
RUNS AT 115.2K. Be sure to use 115.2k for the computer's baud rate.
When using remote control RS232 commands DIRECTLY with the mini-
OPC, send the values within the commands in decimal format. This is
in contrast to other Model 9400 series ACCESS modules the employ a
different chip architecture and require hexadecimal format.
Command syntax with commands shown in " " and example response
data below each command for the mini-OPC when a computer is con-
nected directly to the mini-OPC main board RS232 port (e.g. NOT using
the reader software):

total_conc=0.0
sample_flw=0.00 (lpm)
sheath_flw=0.00 (lpm)
