Chapter 2 Electrical Interface and Connectors This section describes the signals available on the module interface connectors. There are two ways to connect to the OEM Serial Port Adapter, one is via the J1 connector, a 20-pin 2mm pitch pin header, and the other is via the board-to-board (one piece part) connector, J2 through J5. NOTE! J4 and J5 are only available on cB-0702-01 The J2 to J5 connectors on the OEM Serial Port Adapter exist on the module only as a mating PCB-layout pattern.
J1 connector The figure above shows the pin numbering of the J1 connector. J2 connector The figure shows the bottom view of the two PCBs and the pinning of the J2 connector.
J2 motherboard connectors A single-row connector may be used. A connector of the following type is recommended: Samtec: SEI-120-02-GF-S-M-AB The height of this connector is 1.65 mm.

2.1 CMOS Logic Levels The boards cB-0701-01 and cB-0702-01 has some signals that are defined as logic level CMOS signals. The boards are designed to be fully interchangeable between each other. This is possible if the host product has made space for the cB-0702-01 board. This makes it possible to choose freely between a class 1 or class 2 device without any change of the host product. The following voltage conditions are valid. Signal Voltage level Remark Vin Low min - 0.3 V Vin Low max 0.8 V 0.
2.2 Signals in J1 and J2 Connector Maximum load on all In/Out is 3mA. J1 & J2 Pin Name Signal Name Signal Level Type Description 1 VSS Ground Ground 2 VSS Ground Ground 3 VCC_5V Power 3.3V – 6V If only cB-0701-01 is used the range 3.0V – 6.0V is allowed 4 VCC_5V Power 3.3V – 6V If only cB-0701-01 is used the range 3.0V – 6.
J1 & J2 Pin Name Signal Name Signal Level Type Description CMOS In/Out If the level on this pin is set to Low the units goes back to default serial settings. Pin nr. 13 GREEN/Switch-1 Green LED output and Restore switch The “Restore Default” input is only active at unit power up. See the Serial Port Adapter user manual for more information on the Restore switch. See section 2.5 for a design example. 14 BLUE Blue LED output CMOS Output See section 2.5 for a design example.
2.5 Interfacing Examples Example 1 – connection of input/output pins Example 2 – Input/output pins connected to a Host CPU It is recommended to use a serial resistance with a 10 kohm value between the host CPU and the connectBlue module for all input and output pins. NOTE! The RED/Mode pin is a combined output/input pin. The Mode input is only active at power up of the unit. NOTE! The GREEN/Switch 1 pin is a combined output/input pin. The Switch 1 input is only active at power up of the unit.

Chapter 6 Antennas There are 2 different antenna options available: • An internal surface mounted (SMD) antenna. • An “antenna on a cable” maybe connected to a U.FL connector. Three different “antennas on a cable” are available. See chapter about Mounting for more info about antenna placement. This chapter gives only an overview of the qualities of the different antenna options. More detailed information is available in the antenna data sheets. 6.
6.2 Antennas on a Cable (external antennas) The external antennas are connected to the board through a U.FL connector. Some of the antennas are connected directly to the U.FL connector of the board and some is connected using a SMA connected through a short U.FL to SMA adapter cable. Antenna Accessories Part number cB-ACC-18 Name U.FL to SMA adapter cable Connector U.FL and SMA Comment The SMA connector maybe mounted in a panel. The length is of the cable is 12 cm.
Part number cB-ACC-17 Name Puck Antenna Type Polarization Size 70 mm in diameter. Connector SMA Comment To be mounted on the UF.L to SMA adapter cable. The antenna is mounted with a 16 mm hole through a cabinet wall or ceiling. Part number cB-ACC-19 Name CAP24235 (Microblue) Type Microstrip Polarization Linear Size 21x60 mm. 20 cm cable. Connector U.FL Comment Connected directly to the U.FL connector on OEM board.
Chapter 7 Additional Mounting Instructions 7.1 Antenna Issues The unit cannot be mounted arbitrary, because of the radio communication. The unit with an internal surface mounted antenna cannot be mounted in a metal enclosure. If a metal enclosure is required, one of the external antenna options has to be used. Use one of the external antenna options if you are using a metallic enclosure or if there are other reasons why the internal antenna cannot be used. See section 6.
7.4 Using Board-to-Board Connectors Reserved Area Make place for the 20-pin 2 mm pitch pin connector as indicated in chapter 7.2. This allows you to use a standard connectBlue OEM Serial Port Adapter even tough you are not using this connector. Contact connectBlue if there is a requirement to used this reserved area for components. Using the SEI-120-02-GF-S-M-AB Connector from Samtec This connector has a profile height of 1.

Antenna When using the module equipped with the external antennas as described previously the antenna MUST be fixed, not to be able to be removed or replaced by the end user. On modules equipped with SMA-connector, the connector-antenna thread MUST be locked with LOCTITE ® Product 270. LOCTITE ® Product 270 is a single component anaerobic glue. The product cures when confined in the absence of air between close fitting metal surfaces.
