4865B vs the original 4865
The 4865B has a faster processor and faster Ethernet interface
than the original 4865. In addition, the 4865B adds support
for raw socket instruments. The result is a 2.5x to 10x faster
interface depending upon the command, the protocol and the
companion instrument.
rack Mounting
The standard 4865B is housed in ICS's small metal
Minibox™ and is designed for benchtop use or rack mounted
with an optional rack mount kit. The metal Minibox case
provides suburb EMI/RFI suppression. Rack mount kits are
available that hold one or two small 4865Bs or a 4865B and
an ICS interface in a large size Minibox™.

oeM Board Version
Several OEM Board versions of the 4865B are available for
engineers who want to build the 4865B functionality into an
instrument. The OEM boards differ in their connector options:
Part#
Description
115895
20-pin flat ribbon header for GPIB and
horizontal RJ45 connector for Ethernet. Best
version for mounting inside the chassis.
115897
Right-angle GPIB and RJ45 connectors.
115907
Right-angle GPIB and vertical RJ45 connec-
tor. Use when mounting the board against the
rear panel so the GPIB connector protrudes
thru the rear panel of the chassis.
All of the OEM boards have their power switch is removed
and jumpered so that the board turns on with system power.
The standard power jack is replaced by a two-pin friction-lock
header with a retaining clip. The mating connector is ICS P/N
902323 (TE Connectivity part# 6440440-2). Four 2-56 x 0.25
inch threaded standoffs allow the board to be mounded against
any metal plate with adequate clearance under the board.
Use a flat-ribbon GPIB cable like ICS P/N 113644 to extend
the GPIB header on the 115895 OEM Board to the rear panel
of the chassis. The 113644 cable includes metric studs for
mounting the GPIB connector on the rear panel and can be
ordered in any length from 10 to 90 cm.
