5-15. RS-232C Control Method

Signals are connected to the RS-232C connector in a
straight format as shown in Table 5-15-1 RS-232C
connection signals. This is because a crossing connec-
tion is provided inside the unit. Communication condi-
tions are set to meet the conditions given in Table 5-15-2.
Table 5-15-3 shows the command list of RS-232C.
When transmitting the command, be always sure to keep
100 ms interval between each command. Moreover, the
process time is required for a while when turning the
power ON/OFF and/or selecting the input mode. So in
such cases, also be always sure to keep enough intervals
between the commands.
