Software

Using a Third-Party Power Supply

Comtrol supplies a power adapter with the unit. If you want to connect a

third-party power supply to the RocketPort USB Modem Hub, it must be a UL Listed

Direct Plug-In Power Unit identified as Class 2 and

rated 5V DC +/- 10% and 2A +/- 20%. See the previous polarity figure and compare it to the one marked on the back of t he unit above the connector.

Note: Failure to use the correct power supply may

damage the unit and void the warranty.

LED Description

• The Power light (amber) on the front of the unit indicates that there is power coming into the unit.

Note: This does not signify that the unit is working

properly. Use WCOM32 supplied with the driver to diagnose possible problems with the unit.

• One LED for each modem (4). Each LED indicates that the modem has been connected.

Port Identification

Note: If your software applications list does not

contain the Comtrol RocketPort USB Modem Hub, you can select SupraFAXModem 288(336) for fax emulation and Zoom Telephonics Zoom V.34X for modem emulation.

The RocketPort USB Modem Hub uses an internally generated 48 MHz controller specifically designed for a USB port to operate four modem ports. This device and its software enable the USB interface to be transparent to the peripheral and requires no firmware changes. This makes it possible for modems to easily interface with a USB port.

Product Overview 1 of 4

The back plate includes the following connections and switches:

• Power: 5V DC power supply

• USB-B: USB type B Upstream Port

• USB-A: Two USB type A Downstream Ports

• Analog Lines: Four RJ11 modem ports with manual reset.

• Manual Reset Switch Reset a modem if it locks up during use. Use a

sharp thin object (like a paper clip) to push the recessed reset switch.

Using the Speaker

The RocketPort USB Modem Hub includes a speaker that enables you to listen to the call in progress and helps you determine the state of the phone line and the modem. You can control each modem by using the AT commands. All the modems in this hub share one speaker.

The following table lists some of the more commonly used speaker-related AT commands. For a complete list, see the AT Commands set.

AT Command Usage

ATM(0, 1, 2, 3). Enter the ATMn command to set the modem speaker mode. This value is written to S22 bits 2 and 3. Valid values are:

• M0 - Speaker always off

• M1 - Speaker on when making call but off when receiving carrier

• M2 - Speaker always on

• M3 - Speaker off when making call but on when answering

Enter AT&V to displa y the cont ents

of the S-Registers and check the state of the L and M registers.

Using the Downstream Ports

The modem hub includes two USB type A downstream ports, so you can connect multiple peripherals (including additi onal modem hubs) while at the same time supporting your modem hub.

If you want to add more RocketPort USB Modem hubs to this one, you can daisy-chain up to three modem hubs. Each modem hub requires its own power supply.

Safety Notice

Installation of inside wire may bring you close to electrical wire, conduit, terminals and other electrical facilities. Use extreme caution to avoid electrical shock from such facilities. Avoid contact with electrical current by following these guidelines:

• Use tools with insulated handles.

• Do not place telephone wiring or connections in any conduit, outlet, or junction box containing electrical wiring.

Note: Do not work on your telephone wiring at all if

you wear a pacemaker. Telephone lines carry electrical current.

• Telephone wiring must be at least 6 feet from bare power wiring or lightning rods, and associated wires, and at least 6 inch es from other wire (antenna wires, doorbell wires, wires from transformers to neon signs), steam or hot water pipes, and heating ducts.

• Before working with existing inside wiri ng, check all electrical outlets for a square telephone dial light transformer and unplug it from the electrical outlet. Failure to unplug all telephone transformers can cause electrical shock.

• Do not place a jack where it would allow a person to use the telephone while in a bathtub, shower, swimming pool, or similar hazardous location.

• Do not connect to, remove, or modify protectors and grounding wire placed by the service provider.

CAUTION: Do not touch telephone wiring during

lightning!

Operating Conditions

The following tables illustrate RocketPort USB Serial Hub conditions and specifications.

Building Cables

The modem ports use standard telephone-type unshielded twisted-pair cables with RJ11 modular connectors. You can purchase these anywhere commercial telephone products are sold.

Use the following table for pinou t information for t he RJ11 port connectors on the RocketPort USB Modem Hub.

When building cables, use Category 3 (or better) unshielded twisted-pair wiring.

RocketPort USB Modem Hub - Canada

The RocketPort USB Modem Hub connects directly to off-premises Common Carrier facilities using the standard two-wire telephone connection. In some cases, the building’s inside wiring associated with a single line individual server may be extended by means of a certified connector assembly (telephone extension card).

NOTICE: The Industry Canada label identifies certified equipment. This certification means the equipment meets telecommunications network protective, operational, and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The department does not guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own prote ction that the electrical ground connections of the power utility, telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

CAUTION: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority or electrician, as appropriate.

NOTICE: The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone interface. The termination on an interface may consist of any combination of devices , subject only to the requirement that the sum of the Ringer Equivalence

Numbers of all the devices does not exceed 5.

This digital apparatus meets the Class A limits for radio noise for digital apparatus set out in the interference-causing equipment standard entitled: “Digital Apparatus,” ICES-003 of Industry Canada.

When connecting the RocketPort USB Modem Hub to the telephone service, avoid contact with the telecommunications lead wire. Grasp the insulated part of the jack, and do not contact the back of the circuit board. Telephone wiring can carry dangerous voltages from electrical faults or lightning.

External Wiring

Any external communications wiring you may install needs to be constructed to all relevant electrical codes. In the United States this is the National Electrical Code Article 800. Contact a licensed electrician for details.
