ECR-ER-02FD cable
Fig. 3-2
4. Application specification
The following service (SRV) modes are available for the serial data
transfer of the ECR
1) Data transmit (Source side)
X: 0=SSP DATA
2) Data receive (Target)
5. Data format
A single byte image of the RAM data to be transmitted is divided into
a high order 4 bits and low order 4 bits and converted into ASCII
code. Then, the image of the memory is sent in the following format:
Memory top address: 0000H ∼ FFFFH
Top address of the memory to be transmitted in ASCII number.
Page:1F ∼ 27,00
Page of the memory to be transmitted in ASCII number.
Sum check
End code: Hex 0D
NOTE:
• In order that contents of RAM memory may not over-ride pages for
this job, RAM image is sent in unit of 64 bytes from the address
0000. In other words, 128 bytes are sent at one time on the
transmit data format.
