6.2 RS232 Connection
The RS232 connection on the back panel mates with a standard RS232 connector
as indicated in Figure 17 (also see Table 3 and Figure 18). The factory RS232
interface output is an eight-bit data word plus one stop bit and no parity with a
baud rate of 1200. These settings can be changed with the setup menu, and are
saved in non-volatile memory.
