WARNING
This equipment
has been certified to comply with the limits for a
Class B computing device, pursuant to Sub-part J of Part 15 of FCC
Rules.
Only peripherals (computer input/output devices, terminals,
printers, etc.) certified to comply with the Class B limits may be at-
tached to this computer.
Operation with non-certified peripherals is
likely to result in interference to radio and TV reception.
The
IF-232C
is the interface
adapter for connection
between
the
RS-232C terminal of a personal computer and the interface terminals
of transceivers capable of computer control, such as the TS-940S and
the TS-811/711
series.
The interface acts as a voltage converter between the RS-232C port
(-12 to +12V) and the TTL levels of the transceiver (O to +5V), and as
a noise-suppressor.

m@ CONNECTIONS
Note:
1.
After you have confirmed that both the computer and the transceiver
are turned OFF connect the power cable as shown in the illustration.
The RS-232C cable must be shielded to prevent RF interference. The
length of the cable should also be kept to a minimum to prevent RF
interference.
RS-232C standards specific cable lengths less than 50
feet, but this length is impractical for RF applications.
2.
For noise preventation the IF-232C incorporates a photocoupler cir-
cuit which provides electrical isolation between the transceiver and
the computer.
You
should
use a separate
power
supply for the
IF-232C, as well as for the computer.
