Handshake lines are provided for transferring data to external devices and
for inputting data. Other control lines include a Remote line for enabling
external controls, and Trigger, Clear and Reset pulse outputs.
The 4863 and 2363 uses SCPI commands (Standard Commands for
Programmable Instruments) to set their configuration parameters and address.
The configuration settings can be retained in nonvolatile memory and
recalled automatically at power turn-on. This means that the unit has to only
be configured once and then left alone until used in another application. The
SCPI commands can also be used to query the current parameter settings.
Refer to the appendix for additional information about SCPI commands.
At power turn-on, the modules perform a self test of their internal logic. At
the end of the self test, they momentarily display their GPIB or serial address
by blinking the front panel LEDs before displaying their normal Power-on
- Ready condition.
The 4863 is a member of ICS's Minibox product family and is packaged in
a small metal case that is less than 1U (1.6 inches) in height. The front panel
contains the power switch and LEDs which indicate the unit's status. The
rear panel contains the GPIB connector, the Relay Contact/Digital Input
connector and a DC power jack. The 4863 accepts a wide range of DC
voltages and is shipped with an AC adapter for the local power lines.
The Model 2363 is similar to the Model 4863 except that the GPIB connector
on the rear panel has been replaced with a connector that contains the RS-
232 and RS-485 serial signals. Because of the nature of the serial interface,
the 2363 only transfers formatted data as a command parameter and does not
have the 4863's transparent or binary data transfer capability. The 2363 are
network capable and up to sixteen 2363s can operate on an single RS-485
network. All of the 4863's functional descriptions apply to the 2363 unless
otherwise stated.
