RESET. Failure to do so may result in corruption of important EEPROM data. 4. Serial Interface Modes The PKLR2400S provides four different Serial Interface Modes that can be configured for maximum system optimization. These Modes include three Transparent modes and one API mode. The transceiver-to- transceiver protocol is identical for all three Transparent Modes. -
Page 15: Serial Interface Mode 03 - Api
PKLR2400S-10 Specifications 4.3 S 03 – API ERIAL NTERFACE Mode 03 specifies API Mode. In this mode, the OEM has control of the transceiver command set detailed in Section 6.2. Packets are transmitted upon completion of the Send Data* command. -
Page 16: Serial Interface Buffer
When operating in the three Transparent Serial Interface Modes, the initialization sequence is managed by the AeroComm protocol. In Range* commands are not issued and there are no acknowledgements from the transceiver on data delivery unless the OEM protocol has built-in acknowledgements. - Page 17 Checksum Note: All serial data must be transmitted LSB first. Note: The PKLR2400S transceivers are designed to be single threaded, meaning that for every command issued, there is a reply command that indicates the completion of the command issued. There can be no command interleaving.
-
Page 18: Configuring The Pklr2400S
There are many configurable parameters that are stored in the EEPROM on the transceiver. These parameters are read by the AeroComm firmware on power-up or when a reset is executed. If the OEM is writing to the EEPROM, they must use the Write EEPROM Command and enable pin 37 (WR_ENA). These parameters and their respective EEPROM address locations are highlighted in this section. -
Page 19: Channel Number
PKLR2400S-10 Specifications 5.1.3 Channel Number EEPROM Address: 2Eh Size: 1 Byte Default: 00h Range: 00h – Provides 77 unique and non-interfering pseudorandom hopping sequences or Channels. This allows the OEM to configure up-to 77 independent, co-located data networks. It is highly recommended that the OEM change the channel to a number other than 00h. -

Server beacon. This parameter is very useful when operating in a fringe condition to minimize the In Range* and Out-of-Range* commands that may flood the Host. AeroComm has established a default value of 5 seconds through extensive testing. -
Page 23: End Character Definition
PKLR2400S-10 Specifications 5.2.4 End Character Definition EEPROM Address: 3Eh Size: 1 Byte Default: FFh Range: 00h – This parameter is used only when the transceiver is operating in Serial Interface Mode 02. This parameter is ignored when the transceiver is operating in all other modes. The value specified by the OEM will indicate the last character in a data packet. -
Page 24: Serial Interface/Power Down Modes
PKLR2400S-10 Specifications 5.2.6 Serial Interface/Power Down Modes EEPROM Address: 4Ah Size: 1 Byte Default: 01h Range: 01h – There are four Serial Interface Modes for the OEM transceiver including one API Mode and three Transparent Modes. All modes are differentiated by the definition of when data will be transmitted by the transceiver. - Page 25 PKLR2400S-10 Specifications 5.2.6.1 Power Down Modes The PKLR2400S Power Down Modes include a Sleep Walk and Deep Sleep mode. Sleep Walk is for Clients only and Deep Sleep is for Servers only. If bit 7 of the Serial Interface/Power Down Mode Byte is set, the Client enters into Sleep Walk mode. This applies to ALL modes (01-04).

Page 26: Destination Address Control
PKLR2400S-10 Specifications 5.2.6.2 Modem If bit 6 of the Serial Interface/Power Down Mode Byte is set, the transceiver uses all of the modem lines (DCD, DSR, DTR, RI, RTS, and CTS). If this bit is set, then the bit 3 (RTS bit) must be set for the transceivers to operate properly. -
Page 27: Broadcast Attempts
PKLR2400S-10 Specifications 5.2.9 Broadcast Attempts EEPROM Address: 4Eh Size: 1 Byte Default: 04h Range: 01h – The Broadcast Attempts parameter applies only to the Broadcast Modes for all four Serial Interface Modes and specifies the number of times the RF interface will broadcast each packet. The receiving transceiver will discard duplicate packets. -
