NOTE
1 When the external device is equipped with an ISO/EIA
converter, the following items must be noted in Table 5.2.4
(a).
ISO code (.......................)

Left parenthesis “(”of the ISO code punches holes at bits 2, 4 and 5
when used in the EIA code.
Right parenthesis “)”of the ISO code punches holes at bits 2, 4 and 7
when used in the EIA code.
Condition2

2 Control codes DC1 to DC4 are transmission codes output
from the NC. So they need not to be punched on the NC
tape.
(iii) Transmission rate (Baud rate)
The transmission rate (Baud rate) is the number of bits transferred per
second.
The following baud rates are available depending on the system
parameter.
50, 100, 110, 150, 200, 300, 600, 1200, 2400, 4800, 9600.
(Example)
Baud rate : 110
When using one start bit and two stop bits (totalling 11 bits
per character):
Transmission characters/second=
110
11
=10 characters/second
(Max.)
(iv) Cable length
The cable length depends on the external device type. Consult with the
device manufacturers for actual connecting cable lengths.
When cable A (A66L–0001–0041) is used, cable length is as follows
by the specification of NC.
for RS–232C 100m or less ... 4800 bauds or less
50m or less ... 9600 bauds or less
