ESD Warning

Electronic components and circuits are sensitive to

ElectroStatic Discharge (ESD). When handling any circuit

board assemblies including Connect Tech COM Express

carrier assemblies, it is recommended that ESD safety

precautions be observed. ESD safe best practices include,

but are not limited to:

Leaving circuit boards in their antistatic packaging

until they are ready to be installed.

Using a grounded wrist strap when handling circuit

boards, at a minimum you should touch a grounded

metal object to dissipate any static charge that may be

present on you.

Only handling circuit boards in ESD safe areas, which

may include ESD floor and table mats, wrist strap

stations and ESD safe lab coats.

Avoiding handling circuit boards in carpeted areas.

Try to handle the board by the edges, avoiding contact

with components.

Introduction

The ComSync/PCI-104 Gen 3 is a 2-Port Synchronous and Asynchronous Serial board for PCI-104 computer

systems. Although it includes Asynchronous capability, its main focus is for Synchronous communications

protocols, like HDLC, MonoSync or BiSync.

The Serial controller device is an industry standard Zilog ESCC (8523L) which has been well known and

supported, for quite a long time. The ESCC’s main weak point is its small data FIFO’s, which limits maximum

data bit rates to 100 to 200 Kbps in most implementations.

This “Gen 3” board teams the ESCC with an FPGA which allows Serial Data to be transferred between the

ESCC and the system memory very quickly, thus realizing bit rates up to 2.6 Mbps.

PCI-104 Slot Selection

A rotary switch enables selection of the PCI-104 bus slot, as defined in the PCI-104 or PC/104-Plus

Specifications. Positions 0 through 3 select the 4 possible slots. The other positions just mirror the first 4

selections.

RS485, ½ Duplex Bias/Termination Selection

Each port, has a pair of jumpers which enable bias and termination resistors to be applied to the differential

TX/RX± signal pair. J1/J2 for Port-1 and J3/J4 for Port-2. High resistance biasing is always applied when the

jumpers are not installed. The circuit is implemented as follows. These jumpers should be removed for RS422

(full duplex) and RS232 modes of operation. The RX± and CTS± signals have the high resistance (100K) bias

applied permanently.

The jumpers are usually applied in pairs, but they can be used individually for special situations.

Port-1 Port-2

IO Cable

Cable assembly CBG001 (CTIC-00055) can be used with the ComSync PCI-104 Gen 3 product. It provides a

DB-25 style of connector. The pin assignments for this cable are shown in the table above.
