Section 10: Serial Port Interface Protocol
10.4 REAL-TIME PRINTOUT
10-2
Figure 10-1: Serial Port Pin Layout
The serial cable can be a maximum of 25 feet and must be shielded. Connectors
at both ends of the serial cable must have the shield terminated to the full 360
degrees of the connector's metal shell. If sharp bends in the cable or rough
handling is anticipated, use a braided shield.
When a Real-Time display or printout is being transmitted to a printer or PC, a
new line of data is printed every 2 seconds. Every 25th line is a Column
Heading line. A column heading line is also printed any time a value in the
column heading line is changed. A real-time printout is shown below in Figure
10-2.
Note: If the serial output stops transmitting, turn the power off and back on
again or, if connected to a PC, send an XON (Ctrl-9) to reset the
monitor.
