4803: APPLICATION
4803 Relay Driver Board
The 4803DVR Board expands the 4803's
drive outputs by providing forty 300 mA relay
drivers with convenient screw terminals. A
4803 with J3 mounted on the circuit side
piggybacks on the 4803DVR board to make
a compact assembly as shown in Figure 6.
The 4803DVR board can be configured for
all 40 lines as relay driver outputs or for
less drivers and for 8 or 16 4803 TTL I/O
lines. The 4803DVR Board is powered by
the relay power supply and it supplies 5 Vdc
power to the 4803.
Refer to the separate 4803DVR Board
data sheet for complete specifications and
mounting dimensions.
GPIB Connection Cables
ICS offers two styles of the GPIB Connec-
tor/Address Switch Cable Assemblies which
connect the 4803 to a GPIB connector and
Address Switch on the rear panel. Both styles
are business card size, PC board assemblies
with a GPIB connector, metric studs and a 8
position rocker switch. The Address Switch
lets a user set the GPIB address externally
rather than saving the GPIB address in the
4803's flash memory. The two styles of the
GPIB Connector/Address Switch Cable As-
semblies are shown in Figure 7.
ICS also has a GPIB Interface Cable
Assembly that connects the 4803 to a GPIB
connector that mounts on the rear panel of the
chassis. The GPIB connector end includes
two metric studs for mounting the connector
shell to the rear panel. The flat-ribbon cable
assembly is available in any length up to 90
cm. See Figure 8.

Starter Kit
The 4803 Starter Kit provides the OEM de-
signer with everything needed to install and test
a 4803 Board. The Starter Kit includes a 4803
Board, a GPIB Connector/Switch Board Assembly,
the open-end ribbon cable, a GPIB bus cable, a
488-LPCI or 488-USB2 GPIB Controller, ICS's
488.2V3 Drivers and software. The software
package includes a keyboard command line pro-
gram, a Visual Basic configuration program and
example programs. There is a limit of one Starter
Kit per customer.
4803 SDK Kit
The 4803SDK Kit provides everything a user
needs to write custom 4803 programs. The kit
contains the IAR 'C' language compiler, spy debug-
ger, ICS's SDK library disk, manual and spare flash
chips. ICS's library disk contains the SCPI parser

files, 'C' routines, make files and example
4803 files. Refer to the separate 4803SDK
data sheet for more information about the
SDK package.
Note: '-L' in the cable assembly part numbers
stands for cable length in cm from 10 to 90 cm.
