4-12. RS-232C Control Method

4-12.

RS-232C Control Method

Signals are connected to the RS-232C connector in a

straight format as shown in Table 4-12-1 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 4-12-2.

Table 4-12-3 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.
