NOTE
1 When the external device is equipped with an
ISO/EIA converter, the following items must be
noted in Table 5.3.4 (a).
EIA code (....................)
)
o .. ..................
CR
Control out (Comment field start)
Control in (Comment field end)
LF
ISO code (.....................) : ....................
Condition 3 Condition 1
Condition 1
Condition 2
Condition1 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 EIA code
CR
is
LF
in ISO code.
Condition3 EIA code O is : in ISO code.
2 Control codes DC1 to DC4 are transmission codes
output from the NC.
So they need not to be punched on the NC tape.
(3) 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.)
(4) Cable length
The cable length depends on the external device type. Consult
with the device manufacturers for actual connecting cable
lengths.
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
