Section 7. Installation • USR: Drive Size specifies the size in bytes allocated for the "USR:" ram disk drive. • RS-232 Power/Handshake | Port Always On controls whether the RS-232 port will remain active even when communication is not taking place. Note If RS-232 handshaking is enabled (handshaking buffer size is non-zero), RS-232 Power/Handshake | Port Always On setting must be checked. • RS-232 Hardware Handshaking Buffer Size indicates hardware handshaking is active on the RS-232 port when non-zero. This setting specifies the maximum packet size sent between checking for CTS. • Handshake Timeout (RS-232) this specifies in tens of milliseconds the timeout that the CR800 will wait between packets if CTS is not asserted. • Files Manager Setting specifies the number of files with the specified extension that will be saved when received from a specified node. Figure 41: DevConfig Deployment | Advanced tab 7.6.3.1.2 Logger Control Tab • Clocks in the PC and CR800 are checked every second and the difference displayed. The System Clock Setting allows entering what offset, if any, to use with respect to standard time (Local Daylight Time or UTC, Greenwich mean time). The value selected for this control is remembered between sessions. Clicking the Set Clock button will synchronize the station clock to the current computer system time. 101
