TEST has 47K pullup to Vcc. TXD has none. EN has a 47K pulldown 2. Vcc must be a 5v regulated supply (4.75 - 5.25v) 3. Pinout is similar to TX1H, with the addition of pin 8 (located 7.62mm on from pin 7) 4. TXD is inverted RS232 at 5v cmos levels. To connect to a true RS232 device, inverting a level shifter must be used (MAX232 type are ideal, but simple NPN transistor switches with pullups often suffice). With typical microcontrollers and uarts, direct connection is possible. 5. The TXL2 provides transmit side of a simplex link, but provided no two devices attempt to transmit at one time, no further restrictions on data transmission need be made, as all transmit timing, valid data identification and datastream buffering is conducted by the unit. There is no 'transmit enable' pin. 6. This unit is compatible with the RXL2 receiver and the TDL2A transceiver 7. A simple addressing structure is included in the datastream. Units may be programmed onto one of eight addresses (all units are supplied set to default ADDR=0 and default channel=0, 433.925MHz) Figure 3: TXL2 footprint |
