Description

Important! Note “Header Type” Option above for selecting pin header! See “Pin Headers” section below for details.

 
The in485P-M is a RS-485 interface module. It is part of our iMod product range. It enables 3.3V devices (like a Microcontroller for example) to communicate with nodes on a RS-485 network. It has a DIP switch for enabling bias and terminating resistors, that are required for a RS-485 master module (end nodes).

It uses a 1/8 load transceiver chip, enabling 256 nodes on a single bus. It uses the 3.3V Sipex SP3078E RS-485/RS-422 Transceiver chip, which has a 1/8 Load and Failsafe operation. For details on the SP3078, download it’s datasheet from www.exar.com.

The in485P has two rows of standard 2.54mm (0.1″) pin headers. The rows are 0.7″ apart, allowing this module to be mounted on a breadboard or standard 0.1″ grid prototype board. The picture to the right shows some iMod modules mounted on a standard prototyping board.

The pin headers supplied or soldered to this board are selected in the “Header Type” option at the top of this page.

 

Features

  • DIP switch for enabling bias and terminating resistors
  • ±15kV ESD protection for RS485 pins
  • Advanced receiver-failsafe protection for open, shorted or terminated lines
  • Up to 256 Transceivers may share bus (1/8 Unit Load)
  • Very low load for 8x greater fan-out
  • Hot Swap glitch protection RE and DE
  • High quality, 3.5mm terminal block connector
  • Thermal shutdown protects against driver contention
  • Pin Header connectors are gold plated for best possible contact
  • High quality assembly, with brand name, quality components. No cheap, “no name brand” components are used!
  • Module dimension: 22.2mm x 19.7mm (0.875″ x 0.775″)
  • RoHS Compliant
  • Operating Temperature -40°C to + 85°C

Pin Headers

By default this board is supplied with No Pin Headers! The following additional options can be selected in the "Header Type" Option at the top of the page (below price):

No pin header is assembled or included with the board.

Loose 3, 4 and 6.0mm Pin Headers
Click to enlarge

Two unsoldered(loose) Pin Headers are supplied with the board for free. The pin(mating) length is 3.0, 4.0 or 6.0mm. The number of pins depends on the iMod board. For most boards two 1x6 pin headers are supplied.
- Select 3.0mm if module is going to be soldered into place.
- Select 6.0mm if module is going to be plugged into standard 8.5mm high Female Socket.
- Select 4.0mm if module is going to be plugged into low profile 5.7mm high Female Socket.

3.0mm Pin Headers

Pin headers with 3.0mm long pins are assembled. Select this option if the module is going to be soldered into place. The picture on the right shows an example of an iMod module soldered onto a main board.

Header size (2 to 8 pin) depends on iMod board. Many boards will get a 2 pin header on one side, and a 4 or 5 pin on the other.

4.0mm Pin Headers

Pin headers with 4.0mm long pins are assembled. Select this option if the module is going to be plugged into a low profile 5.7mm high female socket (2.54mm grid).

Header size (2 to 8 pin) depends on iMod board. Many boards will get a 2 pin header on one side, and a 4 or 5 pin on the other.

6.0mm Pin Headers

Pin headers with 6.0mm long pins are assembled. Select this option if the module is going to be plugged into a standard 2.54mm female socket.

Header size (2 to 8 pins) depends on iMod board. Many boards will get a 2 pin header on one side, and a 4 or 5 pin on the other.

Round Swiss Pin Headers

Two 6 Pin headers with Round (Swiss) style pins are assembled. Select this option if the module is going to be plugged into female Round (Swiss) Sockets. This is very useful for prototyping! See picture on the right for some examples.

Typically the 6 pin female socket (low profile version) can be used for the main board.

We stock a range of swiss pin headers, available here.

Press-Fit Headers

Press-fit type pins are assembled. They can be pressed into 1.00mm holes on a 1.6mm thick (standard PCB thickness) target board. A press-tool might be required for production assembly. Once fitted to the target board, the board is very secure, and can not be removed by hand any more. The picture on the right shows an example of an iMod module mounted onto main board via press-fit connectors.

We stock a range of press-fit pin headers, available here.
