RS485 is a two wire (twisted pair) network used for party lines where several RS485 devices are attached to the same line in daisy chain style (effectively in parallel). The RS485 lines can theoretically extend for 1.2km.
Only one device can be in transmit mode at a particular time, so the remainder must be in receive mode.
Up to 32 devices can be attached to an RS485 line without a Repeater.
Some means is required to turn on the transmit mode in a device prior to sending.

RS485 termination: The extreme ends of the RS485 line should be terminated with a 120 ohm resistor (i.e. 2 only). RS485 networks should not use a "star" configuration with unterminated stubs. Stations should be close to or on the line. This will prevent reflections causing problems at high speeds.
JED converters have link selectable termination resistors. ADAM converters have a positions for terminating resistors.

RS485/RS422 Receiver Biasing: the receiver can be fed with a small bias current which applies the space condition if the line is broken or not actively driven.
The RS232 send line is then in the space or stop condition also (-ve). JED Converters have a link for setting this.

RS422 has separate dedicated pairs of wires for each direction of transmission between only two devices up to 1.2km apart.
Usually there are just two pairs (send & receive), so data flow must be controlled by XON & XOFF codes.
Hardware handshake would require a third and maybe a fourth pair.

DTE: Data Terminal Equipment,             e.g. a PC:        the transmit pin is pin 2 on a DB25 connector, or pin 3 on a DB9 connector.
DCE: Data Communications Equipment, e.g. a modem:  the transmit pin is pin 3 on a DB25 connector, or pin 2 on a DB9 connector.

If the RS422/485 side of a converter is sending signals to a distant location, an isolated converter is recommended.
This avoids ground loops which can cause data errors if the ground potentials are different at each end of the long line, and gives more tolerance to electrical interference.

JED Serial Line Converters

J995X   RS232C to RS422/RS485, Auto-Tx-On, Isolated

Opto-isolated (1400VAC), bidirectional, (2 or 4 wire). Works reliably up to 115.2kb/sec.
When configured to RS485 mode, the RS485 end normally sits in receive mode, and switches automatically to transmit mode when a character enters the RS232 port.
The baud rate can be set internally with jumpers to ensure that the transmitt mode stays on for long enough for all the bits in the character to be transmitted.
The RS232 side is normally supplied with DB9F on a 45mm ribbon cable, DCE connection (optionally, 25-pin DCE or DTE can be provided).
This side is normally powered from the host (by rectification of the control lines - OK with PC RS232 port).
A pair of screw terminals is provided to power this side if there are problems,
   e.g. if only 3 wires are being used (RX, TX, Gnd) and there is no +ve voltage from host (9 to 12VDC required).
Two internal LEDs shows transmit and receive data. The RS232 side is opto-coupled to the RS422/485 side.

The RS422/485 side has screw terminal connections inside the end of the case, and to preserve the isolation from the RS232 end of the converter, must be powered with its own isolated 9VDC power supply or mains adaptor (e.g. PAK9 below).
RS485 termination and RS485/RS422 receiver biasing jumpers (see above) are provided.
Another jumper can be installed to disable the receiver drive to the RS232 line during an RS 485 transmission.
Plastic Case: 25x50x100mm. Power supply not included.    J995X: $175+GST

External power supply, isolated, 9 to 12 VDC is required
PAK9
Plug Pack Mains Adaptor:
240VAC to 9VDC: $20+GST

"Isolated power supply" means that the power supply output + & - terminals are not connected to ground or anything else.

J995A   RS232C to RS422/RS485, Isolated

Similar to J995X except that the RTS or CTS line on the RS232 side is used to enable the RS485 transmit function.
The RS485 side normally sits in receive mode until the RTS or CTS turns the transmit function on, then off again.
See J995X for Auto-Tx-On (RTS or CTS control not reqd).

The RS232 side has ribbon cable 0.5m, with 25-pin D female connector, (specify male if required).
The ribbon cable can be connected as DTE or DCE. The host powers the RS232 side.
Two internal LEDs shows transmit and receive data.

The RS422/485 side has screw terminal connections, and may be powered with an isolated 9VDC 100mA mains adaptor.
RS485 termination and RS485/RS422 receiver biasing jumpers (see above) are provided.
Another jumper can be installed to disable the receiver drive to the RS232 line during an RS 485 transmission.
Plastic Case: 25x50x100mm. Power supply not included.          J995A: $155+GST

External power supply, isolated, 9 to 12 VDC is required
PAK9
Plug Pack Mains Adaptor:
240VAC to 9VDC: $20+GST

"Isolated power supply" means that the power supply output + & - terminals are not connected to ground or anything else.

J995B as above, (isolated to 1000VDC) but requires 5VDC (regulated) into RS232 side.
Has isolated DC inverter to power the RS422/485 side. J995B: $195+GST

J995C has a larger box with two 240v AC input power supplies to power the RS232 and RS485 sections separately (2750v isolation)
                                                                                  J995C: $250

J995F similar to J995B, opto-isolated, requires either 5v (regulated) or Plug-pack (unregulated 12VDC) into RS232 side.
Has isolated DC inverter (1000DVC) to power the RS422/485 side.

The RS232 side has 10-pin stake connector on PCB which connects to ribbon cable with 9-pin DB9F at outside end.
The RS485 side
has screw terminals.

Option Description:

1. RS232 via a DB9 or DB25 Connector, to 2 or 4 wire RS485. In this mode, external power must be supplied to the unit.
This can be either regulated 5 volts, or unregulated 9 to 12 volts. If regulated 5 volts is used, then the on-board regulator should be removed.
The DB9 connector is female (unless specified male).
The only RS232 signals required are RX, TX & RTS. The CTS signal out of the J995F is tied permanently high on the DB connnectors.
For operation of the RS485 (either 2 or 4 wire), see operating manual.

2. RS232 via 10-way ribbon cable from a number of JED computers, to 2 or 4 wire RS485.
Same as option 1 above, except that power for the unit is supplied on the otherwise unused 10th pin of the ribbon cable.

3. TTL serial communications via a 16 way ribbon cable, to 2 or 4 wire RS485.
In this mode, the RS232 level converter is omitted from the board and all serial communications happen at TTL levels.
These signals would normally come direct from the UART on a piece of equipment without having been converted to true RS232 levels.
As in mode 2, power would normally be supplied via the ribbon cable, 16-way in this case.
If being used with non-JED equipment, the optional on-board regulator with plug pack input can be supplied. For operation of the RS485 (either 2 or 4 wire), see operating manual.

Screw terminal RS485 connections are provided.

J995F 2 or 4-wire version, with DB9F RS232 connection J995FR4: $195+GST

Quatech's ThinQ serial device servers are engineered to Motorola® digital dna™ standards featuring a PowerPC® core with an on-board RISC communications processor. This Dual-CPU design, the auto-sensing 10/100 Ethernet interface, and Quatech's proven high-speed, 921k-baud serial technology offer the best performance in the industry and ensure that your critical business applications won't be harmed by data throughput or latency issues.

Easy to set up and install, ThinQ serial device servers are up and running on your network in 10 minutes or less. A unique Installation Wizard automatically searches for and identifies any ThinQ unit attached to the network, even searching remote subnets if needed. No client software is installed on your PC, just a small set of drivers that configures each ThinQ serial port as a new COM port on the PC. This allows software applications to access the attached serial device as they are designed to, with no custom programming needed. Simply point your software application to the new, "virtual" COM port and you're all set!

Do you have two serial devices that communicate directly with each other and you wish to replace the short serial cable using the distances possible with Ethernet technology? The serial tunneling feature now available on every ThinQ model can do this much easier than you imagine. Set up one ThinQ unit as the master, tell it the IP address of the remote ThinQ unit, and plug them both in. The master will locate and configure the remote unit for you, right out of the box! The two serial devices will then communicate as if connected by a short serial cable; the Ethernet portion will be invisible to the devices.

For remote service and monitoring applications, try our new AutoTCP feature. The serial port can be set up to act as a TCP Client, requesting a connection whenever the serial device is attached and powered on or, if you prefer, whenever serial data is ready for upload to the host computer. You can leave the connection on, or disconnect from the host after a specified period. But when a service request from a remote monitoring PC (with a specified IP address) arrives, ThinQ will act as a TCP server, allow access to the serial device to the monitoring PC, and go back to Client mode when the Server session is finished. This is perfect for remote troubleshooting, support and report generation!

Quatech's "virtual" COM drivers and the Installation Wizard are available for Windows NT4/2000/XP and Linux. ThinQ can be deployed successfully in almost any OS environment however, including Unix and Solaris, via Raw TCP (socket) mode or Quatech's exclusive IntelliSock™ mode. IntelliSock is a flexible and powerful TCP socket service for custom applications that provides capabilities beyond that of Raw TCP mode, such as re-configuring the serial port in the packet header sent with each data transfer. A free Software Developer's Kit (SDK) explains more about this unique feature.

ThinQ RS-232 serial device servers are available in single port and multi-port (two, four and eight port) versions for asynchronous serial devices. Multi-port models are available with DB-9 or 10-pin RJ-45 serial connectors, but custom 10-pin adapters are available for converting ports on the "D" models to RJ-45 for added cabling flexibility and better support for a mixture of serial devices.

ThinQ units are housed in a solid metal case suited for rugged industrial environments and a surge suppression option is available, as are DIN rail mounting for individual units, and rack mount kits for multi-port models.

RS232 to RS232 Isolator Box - Optical Isolation

9POP4 RS-232 Optical Isolator9POP4  RS-232 Optical Isolator

• 2.5 kV isolation
• ESD protection - 15 kV
• Protects up to 4 channels
• 230.4 kbps
• Ideal for laptops, lower power serial ports

The 9POP4 isolates and protects RS-232 equipment from lightning surges,
accidental high voltage shorts, and ground loops.
RS-232 data signals TD, RD, RTS, and CTS are supported at up to 230.4 kbps.
Isolation circuits are 2.5 kV rated and protects valuable equipment while maintaining maximum uptime.

Each side of the isolator receives power from a single 12 VDC power supply to maintain the isolation. This powering configuration allows the device to be used in a system with only one power supply, regardless of the power provided by the RS-232 ports.

The isolator uses DB9 male and DB9 female connectors. The female connector is wired as a DCE and should be connected to a DTE port. The male connector is a DTE and should be connected to a DCE port. If you are connecting a DTE to a DTE or a DCE to a DCE, you will need a null modem adapter.

Power supplies recommended and available from B&B Electronics have been tested and certified. Using any other power supply may bypass or degrade the isolation barrier
