1 General Description

The PCM-2074 allows users to evaluate the CircLinkTM protocol using a TMC2074 CircLinkTM

controller configured for operation in peripheral mode. The PCM-2074 consists of two boards

connected by a 14-pin ribbon cable, which together act as a CircLinkTM Host node, and a software

driver. The maximum communication rate of the two-board-set is 5 Mbps.

The PCM-2074 Main Board contains the following:

On-board TMC2074, configured to operate in peripheral mode

Type II PCMCIA interface using ZiLOG Z1601720ASC

One socket for GPIO connectors

Note: The PCMCIA connection does not support CardBus or ExpressCardTM. It also does not

support the Suspend/Resume functions.

The PCM-2074 RS485 Board contains:

An RS485 transceiver

Two RJ-11 modular jacks

Note: The RJ-11 jacks are not configured to support the CircLinkTM Hub function.

The software driver supplied with the PCM-2074 supports Windows 2000 and Windows XP and comes

with a support library.

Note: Please download the latest version of the driver from SMSC’s website, along with the latest

version of this manual and other application notes relating to SMSC’s CircLinkTM products

4 I/O Connectors

The Main Board has two connectors - CN1 and CN2 - to allow for input/output signals. CN1 comes

mounted with a 14-pin connector, which is used to attach the RS485 Board using a ribbon cable. CN2,

which has no connector attached, can be used for an optional GPIO (General Input/Output) connector.

Note: When using either connector, please adhere to the electrical limits specified in the TMC2074

datasheet.

Table 4.1 below shows the pin-out for the CN1 connector on the Main Board. It also shows the pin-out

for the CN1 connector on the RS485 Board, except that all locations noted as Inputs change to Outputs

and all locations noted as Outputs change to Inputs.

The pin-out for CN2 on the Main Board is shown in Ta b le 4 . 2 below.

5 Reset

The Main Board provides a power-on reset signal which is driven by an MB3771 integrated circuit.

This circuit asserts the power-on reset signal when the Main Board is inserted into a PCMCIA slot, or

when the PC it is attached to is powered on. A second reset signal is provided by the Zilog

Z1601720ASC PCMCIA interface; this signal will reset the TMC2074 when asserted; it is also provided

to the CN2 connector.

6 Monitoring the CMI Decode Signal

When the Hub Function is disable, the CMI decoded signal (an RZ-coded signal) can be monitored on

the TP4 test point connection on the RS485 Board. Note that TP4 is not mounted.

8 Operating Conditions

9 Connecting Twisted Pair Cables to the RJ11 Connectors

The PCM-2074 provides two modular RJ11 jacks for connection to twisted pair cables, which need to

be supplied by the user. These cables should have a characteristic impedance of 125 ohms, in order

to match the impedance built into the board. Each end of the twisted pair cable should have a 125-

ohm termination resistor attached.

Recommended cables and terminators:

Single wire type 125 ohm twisted pair cable (ARC-Cab/125T) from SMSC Japan

125Ωterminator (ARC-Term/125T) from SMSC Japan

For recommendations on the maximum cable-length, minimum node-spacing, and maximum number

of nodes, refer to the TMC2074 data sheet.
