4803: APPLICATION
4803 Connections
The 4803 has three vertical connectors which accept flat ribbon
cable connectors. Two of the connectors contain the GPIB signals.
The 4803 only requires that one of the GPIB connectors be used to
connect it to the GPIB bus. The unused connector can be left open.
The third connector is a DIN connector with the digital I/O signals.
Figure 5 shows some of the connection possibilities.
Connector J1 is a 24-pin connector that is designed for direct
connection to a GPIB bus connector. Use a flat ribbon cable like
ICS's P/N 114439-L that has a 24-pin plug on one end and a GPIB
connector on the other end. (L is the cable length in cm) Punch a
'D' hole on the rear panel with two mounting holes. Use the metric
lock studs supplied with the cable to mount the GPIB connector on
the rear panel of the chassis.
Connector J2 is a 26-pin connector that contains the address
switch input signals as well as the GPIB bus signals. When the
external address function is enabled, the 4803 uses these signals to
set the GPIB address at power-on time. Connector J2 mates with
ICS's GPIB Connector/Address Switch Board Assemblies. The
Connector/Address Switch Assemblies are small, business card
size PC assemblies that mount a GPIB connector and an 8-bit Ad-
dress rocker switch to the rear panel of a chassis. They have a flat
ribbon cable which plugs into J2. The assemblies are available in
two layout styles. Refer to the GPIB Connector/Address Switch
data sheet for the GPIB Connector/Address Switch styles, mounting
dimensions and cable lengths.
Connector J3 is a 96-pin female DIN connector with male pins
that uses rows A and C for the 4803 digital I/O signals and power.
Mating DIN connectors have solder eyelet, wirewrap or solder pins
or use ICS's rainbow ribbon cable assembly.
Mounting Options
Standard 4803 boards have the connectors facing up on the com-
ponent side and are meant to be mounted against a panel or chassis
floor. Access the digital signals with a flat ribbon cable or wire to
the mating solder eyelet connector.
4803 boards are also available with a male DIN connector
mounted on the circuit side so the 4803 can be piggybacked on a
larger PCB assembly as shown in Figure 4. This is a good mounting
method when you already have to layout a PC board for mounting
other devices since it eliminates a cable and wiring. Use a 902257
or a 902058 female DIN connector on the PC board.
