A.4.1 Outline of Universal ROM Writer II specifications
This is a PROM writer for built-in Flash microcomputers. In the onboard serial programming mode, the
SIO Cable supplied with the Universal Writer or the S1C88/S1C63 Serial Connector is used to connect the
Universal Writer and the user target board that has a built-in Flash microcomputer installed. In the
parallel programming mode, the Universal Writer can write data to the built-in Flash microcomputer
through the Adapter Socket for each model installed on it.
It is connected to the host computer (personal computer) via an RS-232C. Its writing and other operations
are controlled by the personal computer.

Function
This LED lights in red with the Universal Writer power on.
These connectors are used to install the Adapter Socket or
S1C88/S1C63 Serial Connector. The Adapter Socket is required for
parallel programming and the S1C88/S1C63 Serial Connector is
required for serial programming. Turn the power off before installing
or removing the Adapter Socket or S1C88/S1C63 Serial Connector.
This is the power on/off switch of the Universal Writer.
Power on with I; power off with O.
A 1 A cartridge fuse is included.
This is the connector for the power cable.
This is the connector for the RS-232C cable.
Secure the cable connector with the screws on the cable connector.
This is the connector for the SIO cable. The SIO cable is necessary for
serial programming.
These pins are connected to the VSS, TXD, RXD, CLK, SCLK and the
VPP signals in the SIO interface.
This switch is used to set the transmission rate.
It has been set to 9600 bps at the factory.
The name 'Universal ROM Writer II' on the
development tool is the old name of the product.
