Chapter 1 EIA-232 asynchronous interface 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.

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 hardware handshaking (RTS/CTS) cable A DB-25 hardware handshaking (RTS/CTS) cable is often sufficient for a terminal, printer, or other DTE device configured for RTS/CTS (hardware) flow control. However, some terminals and printers may have other cable requirements. Consult your terminal or printer manual for this information. For more universal compatibility, use a fully-wired DB-25 terminal/printer cable.
DB-25 fully-wired terminal/printer cable A DB-25 fully-wired terminal/printer cable with the following wiring supports most serial terminals or printers with either software or hardware handshaking. This cable is valid with any Digi DB-25 serial port.

EIA-232: RJ-45 to DB-25 Chapter 4 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).
RJ connector types The following table shows the relationship of various RJ plugs to the Digi RJ-45 10-pin jack. The Digi 10-pin jack can accept any of the listed plug types. The wiring of each plug type corresponds to support of specific capabilities such as software handshaking, hardware handshaking, and the Digi ALTPIN feature.

Chapter 5 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.
Digi EIA-422 connector wiring A terminal, a serial printer, or a serial port for another computer usually functions as a DTE device. A 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 (“-”).
EIA-422 software handshaking (XON/XOFF) cable Use the following table as a guide for EIA-422 wiring. Pin numbers have been omitted because they vary from product to product. For Digi pin numbers, see the section titled "Digi EIA-422 connector wiring" on page 30. For peripheral device pin numbers, see the documentation for your peripheral device.
EIA-422 DTE to DCE (modem) cable Use the following table as a guide for EIA-422 modem wiring. Pin numbers have been omitted because they vary from product to product. For Digi pin numbers, see the section titled "Digi EIA-422 connector wiring" on page 30. For modem pin numbers, see your modem's documentation.
Chapter 6 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.
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. Caution: 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 PowerQUICC™ (Quad Integrated Communications Controller), with an integrated PowerPC™ RISC processor providing four SCCs on the four-port adapter and two SCCs on the two-port adapter.
Cabling information Each Digi-provided cable 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 several 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.

EIA 232 Information RS-232 flow control primer Hardware flow control uses pins RTS and CTS to gate flow back and forth between to connected serial devices. The Data Terminal Equipment (DTE) device uses RTS to start and stop flow from the Data Communications Equipment (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.
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.

Difference between DTE and DCE One of the most misunderstood areas of RS-232 communications is the difference between Data Terminal Equipment (DTE) and Data Communications Equipment (DCE). DTE is typically either a dumb terminal or the serial port on a computer/workstation. DCE is typically a modem, Channel Service Unit/Data Service Unit (CSU/DSU), or another data communications unit. This is all most people need to know about these terms and their meanings.

If this is the case, the forcedcd parameter will need to be turned on for this port at the host.
RJ-11 6-pin to DB-25M terminal/printer cable From Signal Direction Signal RJ-11 To DB-25 4 RxD TxD 2 3 TxD RxD 3 5 SG SG 7 1 RTS CTS 5 6 CTS DTR 20 2 GND GND Shell * Arrows indicate which direction the signal is flowing NOTES: ● This cable utilizes the DTR signal of the terminal/printer for hardware flow control (RTS/CTS). ● Okidata printers may use SSD (pin 11) instead of DTR (pin 20) on DB25 side in above diagram. If this is the case, the printer should be set to SSD+.
RJ-45 4-wire to DB-9M terminal/printer cable - software flow control only From Signal Direction Signal RJ-45 To DB-9 3 GND GND Shell 4 TxD RxD 2 5 RxD TxD 3 6 SG SG 5 1 DCD RTS 7 * Arrows indicate which direction the signal is flowing NOTES: ● This cable can only be used with Software Flow Control (Xon/Xoff). ● Some Unix operating systems require carrier to be present.
