Serial Module equipped with 40-pin 0.5mm pitch board-to-board connector that connects application platform. Electrical mechanical characteristics board-toboard connector specified Chapter Serial interface (see Section 4.1) Power supply (see Section 4.2) Electrical specification interface (see Section 4.3)
Serial Interface
UART_TX, UART_RX, UART_RTS UART_CTS form conventional asynchronous serial data port. interface designed operate correctly when connected other UART devices such 16550A. signalling levels nominal 3.3V inverted with respect signalling RS232 cable. interface programmable over variety rates; even parity; stop hardware flow control. default condition power-up pre-assigned external Flash. Two-way hardware flow control implemented UART_RTS UART_CTS. UART_RTS output active low. UART_CTS input active low. These signals operate according normal industry convention. writing different values register UART_RI continuously polled detect incoming communication. UART_RI signal serves indicate incoming calls. UART_DSR active input. should connected output host. When module running high spped mode (See definition 512), this should asserted host ensure connection maintained. deassertion taken mean that connection should dropped, online command mode being requested. module communicates with customer application using following signals: RS-232 Port /TXD application sends data module's UART_RX signal line Port /RXD application receives data from module's UART_TX signal line

Power Supply
power supply Serial Module single voltage source Vcc= 3.6V.6V. must able provide sufficient current transmit burst which rise 65mA. module includes regulators provide local 3.3V 1.8V. These rails accessible connector monitoring. Power (Vcc) provided connector board-to-board connector Section details power consumption different modes.
Power-On-Reset (Power Cycling Brown considerations).
Module provided with active high reset (Hirose 40way DF12C connector 13). This whose electrical specification found section internally pulled ground through resistor. Upon application power, Power Reset circuit built into module will ensure that unit starts correctly. However module utilises split rail design with some components working some 1V8. Under certain extreme conditions, example when supply voltage module experiences Brown-Out (momentary supply voltage level), rapid power cycle i.e. power switched then within 1second, there possibility that module enter unknown state operation. strongly recommended that application hardware onto which module mounted provides Power-On-Reset circuit with Brown-Out detection capability. This will guarantee that under circumstances module will operate known state. device such Maxim MAX6382XR26D3-T would suitable part perform reset active high push-pull output, 2.63V detection threshold, active reset period 140ms. This inexpensive device available SC70-3 package (2.2mm 2.4mm) requires additional components operate. device used monitor output voltage regulator module (through 27), drives Reset line (pin13) high when supply voltage falls tolerance. schematic below illustrates it's use.

Mounting Serial Module onto application platform
There many ways properly install Serial Module host device. efficient approach mount frame, plate, rack chassis. Fasteners M1.8 screws plus suitable washers, circuit board spacers, customized screws, clamps, brackets 2.2mm diameter holes. Note that care should taken ensure head fixing does interfere with circuit. Nylon fixings recommended. addition, board-to-board connection also utilized achieve better support. antenna (Brown square component side PCB) must influenced other PCBs, components housing host device. proximity antenna large metallic objects affect range performance system. Designers should carefully consider location module type enclosure material that used. prevent mechanical damage, careful force, bend twist module. sure positioned flat against host device.

Power Consumption
current drain from power input line dependent various factors. three most significant factors voltage level Vcc, UART Baudrate operating mode. hardware specification serial module allows voltage range 6.0v Vcc. Tests have shown that there significant difference current draw when Therefore data presented below, pertains levels only. Tests have shown that where power drain issue, best keep lower range. UART baudrate bearing power drain because normal digital electronics, power requirements increase linearly with increasing clocking frequencies. Hence higher baudrates result higher current drain. Finally with regards operating mode significant modes are; idle, waiting connection, inquiring, initiating connection connected.
