Introduction
Service Information S280-77-2 provides descriptive and
application information for the KME4-79-1 and KME4-79-2
Data Port-to-RS232 Compatible Computer Interface
Cable and Adapter Accessories. The accessories are
used in conjunction with a Kyle Form 4C recloser control
and the Form 4C INTERFACE ™ Personal Computer
Software program, running on a DOS-compatible personal computer. Refer to Bulletin KSPS2 for complete
information.
For additional information on the Form 4C control, including a description of the front panel Data Port and the control’s digital communications capabilities, refer to Service
Information S280-77-1.
Description
The data port-to-computer interface cable accessories
shown in Figure 1, provide a convenient means to temporarily connect a personal computer to the front panel
data port of a Form 4C recloser control, for programming
or interrogation of the control.
Either accessory converts the low-power output of the
Form 4C control’s data port circuitry, to the standard
RS232 interface.
The KME4-79-1 accessory permits a temporary digital
communications link from the control’s data port to any
DOS-compatible personal computer with a standard IEEE
25-pin serial port. For personal computers with a 9-pin
serial port; a standard DB25 male to DB9 female adapter
cable must be used, which is readily available through most
computer suppliers. The KME4-79-1 cable is six feet long.
The KME4-79-2 accessory permits a temporary digital
communications link from the control’s data port to any
DOS-compatible personal computer with a standard 9-pin
serial port. The KFME4-79-2 cable is five feet long.

Service Information
S280-77-2
The lengths of the data port-to-computer interface cables
are limited, due to the limitation of the low-power components used in the control data port circuitry and the minimal surge isolation of the data port from the outside world.
The Form 4C control data port is designed for temporary
connection only, of either a personal computer or the
Cooper Power Systems hand-held Data Reader.
9 Volt dc Power Supply
A 9-15Vdc power supply is required to operate the KME479-1 accessory RS232-to-Data Port adapter only. A
power input jack is located on the adapter. The accessory
includes a a 9Vdc battery holder (battery not included)
and cable, which connects to the power input jack. Battery
operating life is approximately 4 hours (less under conditions of extreme heat or cold). It is used in applications
where supply voltage is not readily available, such as
remote substations or recloser line installations and interrogation of the Form 4C control via a personal computer,
is required.
The 9Vdc power supply can also be obtained from any of
the following sources:
1. Personal Computer Serial Port. The serial port of the
personal computer (either a 25-pin or 9-pin serial port)
may include a 9-15Vdc supply. Most computers with a
9-pin serial port do include a 9-15Vdc supply. If the
computer’s serial port provides the necessary voltage,
no external 9Vdc supply should be connected to the
power input jack of the KME4-79-1 RS232-to-Data
Port adapter. Refer to the personal computer instruction manual for additional information.
2. 120 Vac-to-9Vdc Supply Adapter Accessory (Catalog
Number KME4-208, ordered separately). This voltage
supply adapter rectifies and steps down a 120Vac
input to 9Vdc output. It includes a plug that connects
to the power input jack of the KME4-79-1 RS232-toData Port adapter.

3. 9Vdc Supply Cable Accessory (Catalog Number
KME4-207, ordered separately). This cable is identical
to the 9Vdc battery holder and cable supplied, less the
battery holder. The pigtail end is designed to tap the
dc power available at a remote terminal unit (RTU).
The other end of the cable includes a plug that connects to the power input jack of the KME4-79-1
RS232-to-Data Port adapter.
Installation and Operation
To connect the KME4-79-1 or the KME4-79-2 data portto-computer interface cable accessory, refer to the connection diagram shown in Figure 2.
For operating instructions on the use of the Form 4C
INTERFACE™ Personal Computer Software program,
running on a DOS-compatible personal computer, refer to
Bulletin KSPS2.
NOTE: The KME4-79-2 accessory does not require a separate voltage source.
