Plug in modules can control the JX/256 Mainframe from
either TTL Port, Combined IEEE488 BUS / RS232 Serial
BUS or 10Base-T Ethernet LAN.
The Control Module selects any switch in the Mainframe
and Latches or Unlatches the switch in either the Matrix
or Multiplexer Mode and can also request the Status of
selected switches.
In the Matrix Mode, any number of relays can be selected
and Latched or Unlatched.
In the Multiplex Mode, only one relay is selected and
Latched. All others are automatically Unlatched.
This Module has 16 TTL compatible lines for Relay Select, Mode
Select, Status Switch and Strobe.
This Module has both IEEE488 BUS Control with Talk/Listen
features and RS232 Serial Control. The Control Functions are
detailed in Applications Bulletin AP-5.
IF-6 LAN/RS232 INTERFACE
This module interfaces between the Local Area Network and
the RS232 Control Modules using TCP/IP commands as de-
scribed in Applications Bulletin AP-5.
This Manual Control Option has a Keypad and LCD Display on
the front panel. The operator can select any switch and verify
the switch Status via the display.

In this application, the Scanner is required to sequentially select
any one of a number of inputs and switch it to a measuring in-
strument such as a DVM.
For low level signals, or in noisy environments requiring high
common mode rejection, it is advisable to use two pole relays
switching both the Hi and Lo input of the DVM as shown in Fig.
11.
For extremely low level signals such as thermocouples, the LT
type relays with less than 1 microvolt of thermal offset should be
used. For additional noise prevention, the shields from the pairs
of wires can be switched to the Instrument Guard as shown in
Fig. 12.
For very low impedance measurements using a four wire bridge,
it is necessary to switch both Stimuli and Sense lines to each
side of the device under test as shown in Fig. 12. This requires
a total of 4 poles switching with two pole relays as shown in Fig.
13. Any two points can be selected, and the impedance be-
tween these points measured.
