LI-COR LI7200RS, Инструкция по эксплуатации

Страница: 209 / 226

Data are updated to RS-232 at 20 Hz. If the CTS line is toggled, record will be out-
put the next time one is ready. The CTS line is pin 7 on the LI-COR RS-232 Cable,
part number 392-10268. The RS-232 serial pin-out from a DB9 connector on an AT
style computer is defined as:
Pin Signal Description Function Signal at Device
1 DCD Data Carrier Detect Input
2 RD Received Data Input
3 TD Transmit Data Output
4 DTR Data Terminal Ready Output
5 SG Signal Ground
6 DSR Data Set Ready Input
7 RTS Request To Send Output
8 CTS Clear To Send Input
9 RI Ring Indicator Input
A possible wiring configuration using the LI-COR RS-232 cable, part number 392-
10268 to a computer would be:
LI-COR CABLE DB9 ON HOST COMPUTER LI-COR CABLE
Function PIN Function
Ground PIN 5 Ground
Receive Data PIN 3 Transmit Data
Request To Send PIN 8 Clear To Send
Transmit Data PIN 2 Receive Data
Clear To Send PIN 7 Request To Send
Data Terminal Ready PIN 6 Data Set Ready
Note about Embedded Software RS-232
Communication Priorities
The RS-232 hardware and software trigger does not tap directly into the same data
stream that is output to the DAC's and the SDM. The trigger actually sends a
request to the instrument to output a single data record over the RS-232 port. The
processing that is incurred to do this is relatively lengthy. The RS-232 task is also a
low priority, so considerable latency could occur. If you want to output data that is
tightly synchronized to an input stimulus you should use the SDM output or
sample a DAC output based on your trigger; don't use RS-232.
