The Shuttle PCP11 COM Port Adapter Cable (P/N 45R-DS8311-0101) is a specialized accessory designed to expand serial connectivity options for compatible Shuttle XPC systems. This adapter provides additional RS232 serial COM ports via a 9-pin Sub-D external connector, ideal for industrial, business, and embedded applications requiring robust serial communication.

Compatible with multiple Shuttle XPC barebone models including all-in-one units (P20U, P22U, P51U, P52U), slim series (DS10U, DS20U, DS50U), and cube models (XH410G, XH510G(2), XH610G(2), SH610R4), the PCP11 allows upgrading the number of available COM ports. For example, on certain all-in-one systems with two built-in COM ports, it extends connectivity up to four RS232 serial ports. On slim models, this adapter can replace a VGA port to add COM functionality.

It features a 10-pin (2×5) female internal connector with a 2 mm pitch, connecting to the motherboard, and includes a 9-pin ribbon cable approximately 21 cm long for flexible installation. The package comes complete with the COM port adapter, two mounting screws with UNC 4-40 threads, and an installation guide to streamline setup.

Key benefits include enhanced serial control capabilities, versatile compatibility across Shuttle XPC models, and reliable RS232 signaling via standard Sub-D connectors. This accessory is essential for users who require expanded legacy device support or multi-serial port configurations on Shuttle XPC platforms.
