GE IS200EPMCH1A IS200EPMCH1ADB

Compact Expansion Module for GE Mark VI Processors

The GE IS200EPMCH1A IS200EPMCH1ADB adds PCI-based functionality to host processor boards. This mezzanine card belongs to the Mark VI series from General Electric. It plugs directly into a compatible carrier board. Therefore, it provides additional communication or memory capabilities without replacing the main board.

Physical Dimensions and Lightweight Construction

This daughterboard measures 7 cm in width, 5 cm in height, and 1.2 cm in depth. The GE IS200EPMCH1A IS200EPMCH1ADB weighs approximately 0.04 kg, which makes it extremely lightweight. Its small form factor fits into tight spaces on the carrier board. Consequently, you can install it without removing adjacent components.

Connector Layout and Component Configuration

The GE IS200EPMCH1A IS200EPMCH1ADB features one 64-pin mezzanine connector for carrier interface. It also provides two test points for diagnostic access. This board contains one PCI bridge chip and two memory modules. Additionally, it includes four energy storage capacitors for stable logic operation.

Energy Storage and Logic Stability Performance

The GE IS200EPMCH1A IS200EPMCH1ADB stores minimal energy for logic hold-up. Its four capacitors provide 188 µF of total capacitance. This storage filters out high-frequency noise from the PCI bus. As a result, the board maintains stable data transfer during normal operation.

Role Within the Mark VI Speedtronic System

You will typically find the GE IS200EPMCH1A IS200EPMCH1ADB mounted on a main processor carrier board. It adds PCI expansion capabilities without consuming extra rack slots. Moreover, this daughterboard supports both master and target PCI modes. Its 64 MB memory provides additional storage for application code.

Installation and Handling Guidelines

Use the GE IS200EPMCH1A IS200EPMCH1ADB as a direct replacement for older EPMC revisions. Always observe ESD precautions before handling this sensitive board. The 64-pin connector aligns with a single keying guide. This daughterboard requires no additional configuration or software drivers. Simply press it firmly into the mating connector until the locking clips engage.
