7. RS232 Interface
1) Port 2 (CH1)
2) Port 1 (CH8)
The No.9 pin signal of the Port 1 (CH8) can be selected between the
/CI signal and the +5V signal by changing the connection of the SW2
(initial value: /CI signal)
NOTE:
Optional bar code reader: When connecting an ER-A6HS1, connect
it to the Port 1 (or 2) and switch the No.9 pin signal to the +5V
signal.
When connecting other RS232 devices to either the Port 1 (or 2),
make sure the No.9 pin signal is proper before connecting the device.
If you want to connect an RS232 device to the ECR with the No.9
pin of the port 1 (or 2) set to +5V, make sure the AC cable of the
ECR is disconnected from the wall outlet to protect the device.

2-4. TPRC1 (F258024PC)
1) General
TPRC1 is the LSI circuit of the peripheral circuits of the microcom-
puter required for thermal printer control.
Fig. 2-6
The CPU is designed for use with H8/500. The bus I/F, however, is
not restricted to the design concept.
The printer is designed mainly for use with PR-58. However, the
thermalhead composition (the dot number and the block number) is
rather flexible.
