TECHNICAL INFORMATION
C-2 Sysmex SF-3000 Operator's Manual -- Revised September 1995
1. SERIAL INTERFACE FOR HOST COMPUTER
A serial interface is available on the Main Unit rear panel for connecting to a host
computer. The bit serial voltage type, which conforms to the RS-232C interface, is used
for input and output to and from the SF-3000.
1.1 Connection
Connect an EIA RS-232C V.24 standard 9-pin D-SUB, female (body = female and pins
= male) connector (DB-9S) to the serial interface on the Main Unit rear panel. Fixing
screws for this connector have an inch thread.
1.2 Input/Output Signals
PIN SIGNAL NAME FLOW DIRECTION
1
2 Receive Data (RxD) IN (From Host to SF)
3 Transmit Data (TxD) OUT (To Host from SF)
4 Data Terminal Ready (DTR) OUT (To Host from SF)
5 Signal Ground (SG)
6 Data Set Ready (DSR) IN (From Host to SF)
7 Request to Send (RTS) OUT (To Host from SF)
8 Clear to Send (CTS) IN (From Host to SF)
9
