5.5.2 Interface

1) Connector
D-sub 9 pins
2) Pin layout
Pin No. Signal
1 NC (not connected)
2 TxD (Transmit Data)
3 RxD (Receive Data)
4 NC (not connected)
5 GND
6 NC (not connected)
7 NC (not connected)
8 RTS (Request To Send)
9 NC (not connected)
3) Baud Rate
4800 bps (standard)
(switch-able to 1200, 2400, 9600, 19200, 38400 bps)
(NOTE) Set the baud rate to match that of the computer presently in use. Moreover, in the case that the RS-232C
cable is very long, we recommend that you make the baud rate lower.
4) Data Format
Start: 1-bit
Data: 8-bit
Parity: 0 (no parity)
Stop: 1-bit
5) Connection
Control PC
(with D25 serial port )

* D-sub 9-pin/D-sub 25-pin conversion tables are now available on the market.
(NOTE) As computer manufactures may not use the same pin assigments. In case of communication difficalties,
please check pin functions not just pin numbers.
