EIA-232 Asynchronous Interface
Chapter 1
General EIA-232 Cable Information
Use this information to determine the proper EIA-232 cable requirements
for your application.
Physical Cable Characteristics
EIA-232 serial interface cables should be shielded, low capacitance cables,
designed specifically for serial data transmission.
Grounding Requirements
EIA-232 interface cables should have the shield grounded at both ends of
the cable. Digi recommends Chassis Ground, available on the shell of
Digi's DB-25 connectors, and pin 4 of a 10 pin RJ-45 connector.
Environmental Requirements
While good shielding provides reasonable protection against "noise"
(electromagnetic interference, or EMI), cables should still be routed away
from noise sources wherever possible. Avoid laying cables in close
proximity to transformers, generators, motors, fluorescent lights, etc.
Data Rate Information
The maximum data rate that can be used for EIA-232 connections is
primarily determined by the quality and length of the interconnecting cable.
The quality of the cable (for transmission purposes) is generally
determined by the capacitance per foot rating of the cable.
The following table gives the recommended maximum cable length for a
given data rate. Longer cables may be implemented at your discretion.
Note that not all Digi products support all of the data rates listed below.
Data Rate vs. Cable Length
Data Rate (bps)
Maximum Cable Length
57,600 or less
100 feet
115,200
80 feet
230,400
40 feet
460,800
20 feet
921,600
10 feet
Notes:
•
•
Chapter 3
The maximum length is the amount of cable that is connected to a
Digi supplied interconnect device, such as Quad or Octa cables and
boxes.
The maximum length is based on a cable rated at the following:
12.3 pF/foot, conductor to conductor
22.4 pF/foot conductor to shield
EIA-232 Asynchronous Interface

•
•
In situations where low-capacitance cable is unavailable, or very
long cable runs are required, "short-haul" modems can be used to
increase the effective range of the EIA-232 interface. Short-haul
modems are similar to standard modems, except that they are
connected directly to each other via a cable instead of going through
a telephone circuit.
Use only externally-powered short-haul modems with Digi products.
Transmission Errors
If transmission errors occur, follow this procedure to determine the cause of
the problem:
1. Reduce the baud rate.
2. Reduce the cable length.
3. Use a cable with a lower capacitance per foot rating.

This cable is a three-wire null modem cable. Transmitted Data on one end
of the cable is connected to Received Data at the other end, and vice
versa. The male DB-25 end can be plugged directly into most serial
terminals and printers without any adapters. The female DB-25 end plugs
directly into any Digi DB-25 serial port.
DB-25 4-Wire Hardware Handshaking (DTR) Cable
The following four-wire cable is often sufficient for an older terminal, printer,
or other DTE device configured for DTR (hardware) flow control. However,
some terminals and printers may use a signal other than DTR for flow
control. In addition, some terminals and printers may have other cable
requirements. Consult your terminal or printer manual for this information.
For more universal compatibility, use a full-wired DB-25 terminal/printer
cable.

DB-25 Modem Cable
To connect a DB-25 equipped asynchronous adapter to a modem, use a
standard "straight-through" cable. A straight-through cable has a DB-25
female connector at the Digi end, and a DB-25 male connector at the
modem end. All 25 pins are connected, 1 to 1, 2 to 2, 3 to 3, etc. Use
shielded cable, and connect pin 1 of each connector to the cable shield.

Digi RJ-45 Connector Pin Assignments
10 pin RJ-45 plugs may be difficult to obtain in the retail market; therefore,
most Digi device driver software incorporates an optional feature called
ALTPIN, which swaps the logical functions of DSR (Data Set Ready) with
DCD (Data Carrier Detect).
When ALTPIN is enabled, DCD becomes available on pin 1 of an 8 pin RJ45 connector (equivalent to pin 2 of a 10 pin connector).

EIA-422 Asynchronous Interface
General EIA-422 Cable Information
This section applies to Digi products equipped with EIA-422 asynchronous
interfaces.
Physical Cable Characteristics
EIA-422 interface cables should be shielded twisted-pair cables. Each
signal requires two leads (one twisted pair of wires) to complete a balanced
voltage digital circuit. The shield should be connected to the Chassis
Ground of the devices at both ends of the interface cable.
Interface Signaling
The EIA-422 interface provides four signals: Transmitted Data (TxD),
Received Data (RxD), Request To Send (RTS) and Clear To Send (CTS).
The functions of these signals are identical to their EIA-232 counterparts.
Grounding Requirements
EIA-422 interface cables must provide a ground path between the devices
to be connected. This ensures the integrity of data transfers and control
signals. This should be connected to the Chassis Ground of each device.
Digi recommends using the cable shield for this purpose.
Digi EIA-422 Connector Wiring
A terminal, a serial printer, or a serial port for another computer usually
functions as a DTE device. The Digi adapter is also a DTE device. To
connect a DTE device to another DTE device a null modem cable or
adapter must be used.
Two wires (one twisted pair) are required for each signal, a positive lead
("+"), and a negative lead ("-"). The "+" leads at one end of the cable must
be connected to the "+" leads at the other end, and the "-" leads at one end
must be connected to the "-" leads at the other end.
Incorrect wiring could result in damage to the connected devices. The
following table shows the pin configurations for the EIA-422 versions of
Digi DB-9, DB-25, and RJ-45 connectors.

EIA-485 Asynchronous Interface
General EIA-485 Cable Information
This section applies to Digi products equipped with EIA-485 asynchronous
interfaces.
Physical Cable Characteristics
EIA-485 interface cables should be shielded twisted-pair cables with a
maximum of 4000 feet in length. Each signal requires two leads (one
twisted pair of wires) to complete a balanced voltage digital circuit. The
shield should be connected to the Chassis Ground of the devices at both
ends of the interface cable.
Interface Signaling
The EIA-485 interface provides four signals: Transmitted Data (TxD),
Received Data (RxD), Request To Send (RTS) and Clear To Send (CTS).
The functions of these signals are identical to their EIA-232 counterparts.
Grounding Requirements
EIA-485 interface cables must provide a ground path between the devices
to be connected. This ensures the integrity of data transfers and control
signals. This should be connected to the Chassis Ground of each device.
Digi recommends using the cable shield for this purpose.
Termination Information
A DIP switch controls the termination of many Digi devices. Most Digi
devices use the #4 switch to control termination. When the switch is down,
termination is off and there is no termination. To set termination on the
device, move the #4 switch to the up position. Termination is recommended
in a multi-drop line for the last networked device. Termination also biases
the line.
Check your Digi device for its ohm rating, but 100 ohms is the nominal
setting in Digi products.
Chapter 8
EIA-485 Asynchronous Interface

Digi EIA-485 Connector Wiring
Two wires (one twisted pair) are required for each signal, a positive lead
("+"), and a negative lead ("-"). The "+" leads at one end of the cable must
be connected to the "+" leads at the other end, and the "-" leads at one end
must be connected to the "-" leads at the other end.
Incorrect wiring could result in damage to the connected devices. The
following tables show the pin configurations for the EIA-485 versions of
Digi DB-9 and RJ-45 10 pin connectors.

DataFire 2000 Sync Adapter
Chapter 7
Introduction
The DataFire SYNC 2000 adapter is an intelligent, high performance
synchronous communications adapter that is available in versions for PCI
bus and Compact PCI (cPCI) bus compatible systems. The basic design
comes with a Motorola MPC860 PowerQUICCô (Quad Integrated
Communications Controller), with an integrated PowerPCô RISC
processor providing four SCCs on the four-port adapter and two SCCs on
the two-port adapter.
DataFire SYNC 2000 adapters offer a Universal Interface Bus (UIB)
capable of supporting a different interface on each port. The UIB
automatically configures the electrical interface of a port based on the type
of Digi cable connected to the port. That is, you can select an interface type
for a port just by connecting the appropriate cable between the adapter and
the peripheral device. You can use any combination of interface types to
connect up to two peripherals to the two-port version, or up to four
peripherals to the four-port version.
Features
The DataFire SYNC 2000 adapter has the following features:
• High-speed synchronous communications ports
• Automatic cable detection
• SurgeBlockô surge protection
• All major electrical interfaces are available as UIB cable options,
including X.21, V.28 (V.24)/EIA-232, V.35/RS-449, V.36, EIA-422,
and EIA-530
• Available with an optional PowerPC 603 processor, 4 megabytes of
RAM, and Frame Relay or X.25 public data network protocols
• The DataFire SYNC 2000 adapter has gained homologation
acceptance for most European countries
Cabling Information
Each cable provided by Digi has a 68 pin Ultra SCSI connector on one end,
which attaches to a port on the Universal Interface Bus. The other end of
the cable will provide signals according to the interface standards.
Each port on the SYNC 2000 adapter can be configured to use any one of
a number of cables. Cables are available as V.35, EIA-530/EIA-422, X.21,
and EIA-232/V.28. The cable type is automatically detected by the
Universal Interface Bus.
If you require multiple cables of one type, you may order additional cables
from Digi. To extend the length of a Digi cable, use standard interface
cabling between the end of Digi's cable and the peripheral.

Recommendations
Digi recommends shielded cables (15 pF or less capacitance per foot) for
all installations.
The FCC requires the use of shielded cables to comply with EMI/RFI
emission limits. In addition, cables that run long distances or through
electrically noisy areas are subject to voltage surges that can cause data
errors or equipment damage. EIA-232 specifies a maximum cable length of
50 feet. If you run cables farther than 50 feet, you increase the risk of surge
damage and data loss. (However, using shielded cable of 10-15 pF
capacitance per foot somewhat lessens the risk of data errors.)
When routing your cables, do not run them parallel to AC wiring or on top of
fluorescent light ballasts. Bundling several EIA-232 cables is acceptable

EIA 232 Information
RS 232 Flow Control Primer
RS
RS-232 Flow Control Primer
Hardware flow control uses pins RTS and CTS to gate flow back and forth between two connected
serial devices. The DTE device uses RTS to start and stop flow from the DCE device, and the DCE
device uses CTS to gate flow from the DTE device. This method is popular for higher speed
connections where flow control reaction time is more critical. It's also popular where the data stream is
such that embedded flow control characters can not be tolerated by the protocol running on the link.
The cost is that you have to run two more wires in the cable.
Software flow control uses special START (XON) and STOP (XOFF) characters embedded in the
data stream to gate flow. In other words, the receiving device would send a STOP character (typically a
control-s) to the sending device to halt flow. It would then later send a START character (typically a
control-q) to resume flow. This method of flow control is more popular for slower links whose protocol
can support embedded flow control characters. It's popular because it only requires that you run 3 wires
for the link to function: Receive (RxD), Transmit (TxD), and Ground (GND).

Fiber Optic Cable Specifications and Source CSP
Fiber Optic Cable Specifications and Source
CSP, Inc. can provide you with reliable fiber assemblies certified to function properly with DigiBoard
equipment.
Fiber is the best solution for transmitting large amounts of data over long distances at high speeds
without interference
or lost data caused by outside factors such as weather, radio frequency signals or other electrical noise.
The ST connector provides these features as well as strong performance and reliability characteristics.
The ST connector
also helps maintain close tolerances when mating connectors in an adapter. The ST connector is easily
recognizable because
of its bayonet style attachment/detachment mechanism.
The ST also offers superior loss characteristics because the ferrules are made of stainless steel or
ceramic and the connector
has a spring-loaded mating system that exerts consistent pressure on the ferrule tip when inserted in an
active device or an adjoining
fiber. These impressive characteristics have allowed the ST connector to become the most widely used
connector in Local
Area Networks (LANs).
CSP fiber optic assemblies are made at the length you specify with or without an optional pulling eye
to meet your individual requirements.
CSP assemblies are made with FDDI grade fiber and tested to meet EIA/FOTP specifications. CSP
complies with the requirements
of the 1990 National Electrical Code (NEC) for Optical Fiber Cables - Article 770.

Digi TS DB25M Console Adapter (4-pack)
All RJ45 cable adapters are 8-pin.
Altpin should be turned on when using this cable adapter so that DTR will drive DCD (standard usage).
If altpin is turned off, the hardware signal on RJ45 pin 1 becomes DSR instead of DCD. This alternative can be used if
DCD is not required, and DSR is needed instead.
This cable adapter utilizes the RTS signal of the serial device for hardware flow control (RTS/CTS).

Difference Between DTE and DCE
DTE vs. DCE
This is one of the most misunderstood areas of RS-232. DTE stands for Data Terminal Equipment, and
DCE stands for Data Communications Equipment. DTE is typically either a dumb terminal or the serial
port on a computer/workstation. DCE is typically a modem, DSU/CSU, or other piece of data
communications equipment, hence the names. This is all most people really need to know about these
terms.
Where it gets confusing is when you start to talk about signal definitions and direction. For example,
it's easy for someone to understand that when you transmit data, you send it out. However, when you
talk in terms of DCE, it becomes an input signal. This is because the specification was written from the
perspective of the DTE end of the link. Another example is the Receive Data signal is an input to DTE,
but an output from DCE.
Therefore, a straight through "one to one" cable is all that is necessary between a modem and a
standard DTE serial port. However, if you want to connect two DTE ports together, you have to
simulate the existence of the pair of DCE devices, typically modems that would normally be between
the two DTE devices. This is where the null-modem device or cable comes in.
