INTRODUCTION
SCOPE OF THIS MANUAL
This manual is intended for use by experienced tech-
nicians familiar with similar types of commercial grade
communications equipment. It contains all required serv-
ice information for the equipment and is current as of
the publication data. Changes which may occur after
publication are covered by either Service Bulletins or
Manual Revisions. These are issued as required.
ORDERING REPLACEMENT PARTS
When ordering replacement parts or equipment infor-
mation, the full part identification number should be in-
cluded. This applies to all parts: components, kits, or
chassis. If the part number is not known, include the
chassis or kit number of which it is a part, and a suffi-
cient description of the required component for proper
identification.
SERVICE
This radio is designed for easy servicing. Refer to the
schematic diagrams, prited circuit board views, and
alignment procedures contained within.
NOTE
WE CANNOT guarantee oscillator stability when us-
ing channel elements manufactured by other than KEN-
WOOD or its authorized agents.

Writing Data
1. Overview
1. When the KPT-20 is used, refer to the KPT-2R man-
ual.
2. Self programming or cloning.
* Write to self (Use programming plug KCT-2).
e Write to another set (Use cloning cable KCT-1).
1-1. Overview
The TK-230 with keyboard has the ROM WRITER
function. It writes T.SW data, system data (such as scan
and frequency set for each channel), and signalling data.
The TK-230 with keyboard can write data to itself. It can
copy from radio with keyboard. Itswrite data and key-
board data to a radio without a keyboard (CLONE and
COPY functions). In this case, radio will not action.
1-2. Connection
When the TK-230 with keyboard is used as a ROM
writer, it is controlled through the CONT, EDA, and RW
signal lines of the universal connector. The EDA is the
main microcomputer data input. The TK-230 functions
as a ROM writer when the CONT and RW signals are
as follows:
CONT =0, RW = 0 > Write to self
CONT = 1, RW = 0 > Write to another set

WRITING METHOD
1-3. Data to be written
The following three types of data are written into the
EEPROM of the TK-230:
e System-related data ,
- Set variations (T.SW 1/2), BUSY LOCKOUT, PRIORI-
TY CH, DEL/ADD, AC CONT, SCAN).
- Basic set time (TOT, BUSY LOCKOUT DELAY, P.S).
- SCAN (LOOK BACK A/B, SCAN RESUME, etc.).
e DTMF-related data (only with keySoard)
- CONNECT ANI
- DISCONNECT ANI
e Data set for each channel
- Frequency data
- Signalling data
- Power H/L data
- Fixed DEL/ADD data.
-SW1, SW2, data
The Power H/L, DEL/ADD, SW1 and SW2 are set in-
dependently of the frequency.
CAUTION
1. Before connecting an options (KMC-11, KCT-1,
KCT-2 etc.) to the universal connector of the radio,
be sure to turn the radio POWERswitch off.
2. Alphanumeric data of the channel or repertory dial
cannot be written by writing by a set. Use KPT-20
+ (2R).
3. The iF and PLL step cannot be modified by writing
by a set. Therefore, set the IF and PLL step by
using KPT-20 + (2R).
4. Each frequency data and tone data itermn is written
into the ROM for each system. To modify system
data, perform the operation until the modified
system number appears, then perform the next
operation.
1-4. System data
Data written by the ROM writer is classified into sys-
tem data and CH data. Data associated with the basic
specifications of the TK-230 is set. System data can be
set for system 1 to 5. The contents of the data are as
follows:
- T.SW 1/2 (@.0/ %& [fp ) function setting
- Scan stop mode
- Priority Yes/No
- DEL/ADD
- Timeout timer (TOT)
- Power save time
SYSTEM 3} . CONNECT/DISCONNECT ANI
(With keyboard only)
- Fixed (programmable) DEL/ADD
- Power H/L
-SW1, SW2
- Scan resume
- Scan lookback (A)
- Scan lookback (B)
- Fixed priority CH
1-5. Data for each channel
Data set for each channel includes :
- Frequency data
- Signalling data
Frequency data is the TK-230 operating frequency.
Signalling data is QT/DQT setting data. Each data item
is set for TX/RX.
1-6. Key functions and layout
When programming plug KCT-2 is used with the
TK-230 with keyboard, the system enters the ROM
WRITER mode.
