TecNet TD-2400MD 2.4GHz Data Modem Reference Guide
Thank you for your purchase of the TD-2400MD Data Modem, the world’s first System-
on-Chip (SoC) radio designed for low power and low cost to meet industry standards
protocol IEEE802.15.4 and ZlgBee. The TD-2400MD combines phenomenal
performance through an enhanced 8-bit 8051 MCU with internal 96KB of FLASH and
8KB of RAM; for user application program and data, hardwired MAC and AES-128.

3. Selecting RS-232C and TTL Serial Communication
Serial communication can be used through RS-232C and TTL Level. The first default
value is set to RS-232C communication. If the user needs to change from RS-232C to
TTL Levels, it can be done by R24, R25, R26, R27, R11, R12, R13, R14, R15, R16,
R17 and R18 resistance. This equipment can be used only by 3Wire communication
using TX Data, RX Data, and Ground. The selection of using RS-232C and TTL serial
communication is shown in the table below. TTL Serial Level is DC+3.0V.
