OEM Board Connections
OEM Board versions of the 4867/2367 are equipped with vertical headers
for the GPIB interface, serial interface and remoting the LEDs. The number
of headers varies with the board configuration. Terminal block J3 is the
power connection. Connector J4 is the serial header and contains the RS-
232 and RS-485 signals. Connector J5 is the GPIB header and contains the
address switch input signals as well as the GPIB bus signals. Connector J5
mates with ICS's GPIB Connector/Address Switch Board Assemblies.
Connector J7 is located near the LEDs and contains the LED drive signals.

centers. Pin 8 is the key position and is omitted from the header. The Serial
Header location on the 4867/2367 board is shown in Figure 2-10. Signal pin
