Figure 4-5, Model 7230 Rear Panel Layout
As shown in figure 4-5, the power input socket, power switch, digital I/O port,
RS232, USB, LAN connectors, and eleven BNC signal connectors are mounted on
the rear panel of the instrument. Brief descriptions of these are given in the following
text.
The model 7230 requires regulated DC power supply voltages of 15 V and +5 V to
operate, which are provided via the SIGNAL RECOVERY Model PS0110 power
supply module that plugs into this 5-pin DIN power input connector.
CAUTION: The Model 7230 must only be powered from the Model PS0110 power
supply module provided with it. Use of other power supplies, except with the prior
written permission of SIGNAL RECOVERY, will invalidate the warranty.
Press the end of the switch marked I to turn on the instrument's power, and the other
end marked O to turn it off.
This connector provides eight TTL lines, each of which can be configured as an
input or output. When set as an output, the line can be set high or low, and when set
as an input, the applied logic state can be read.
The port is most commonly used for controlling auxiliary apparatus, such as lamps,
shutters and heaters, and reading status signals from auxiliary equipment. Pinouts for
this connector are given in appendix B.
This 9-pin D type RS232 interface connector implements pins 1, 2, 3 and 7 (Earth
Ground, Transmit Data, Receive Data, Logic Ground) of a standard DTE interface.
To make a connection to a PC-compatible computer, it is normally sufficient to use a
three-wire cable connecting Transmit Data to Receive Data, Receive Data to
Transmit Data, and Logic Ground to Logic Ground. Appendix C shows the
connection diagrams of cables suitable for computers with 9-pin and 25-pin serial
connectors. Pinouts for this connector are given in appendix B.
This connector allows the instrument to be connected to a 100-BaseT or 10-BaseT
network for control from a computer connected to the same network using either the
built-in web based control panels or separate software packages, such as a LabVIEW
driver, SIGNAL RECOVERY Acquire, or SRInstComms. The IP address can be set
