[Caution] This page explains the details of the discontinued model of BC-ANT-SERIAL. If you are looking for the technical information of the present ANT module, please look at [[this page>]]. Thank you.
BC-ANT-SERIAL is an ANT wireless communication module. ANT is a low-power data wireless communication network protocol, which runs in 2.4GHz ISM band. ANT can handle form a simple peer-to-peer to a complex fixed mesh topologies. ANT provides hardware solutions for flexible and adaptive network operation and cross-talk immunity.
This module has been certified by the Japanese regulatory agency and has received Technical Conformity. The label of the certification number is put on the module. It is illegal if you remove the label and put it on another device. Even though you remove and damage the label and use the device, it will be considered as illegal. If you modify the module, such as replacing to its antenna or changing its high frequency circuit, Technical Conformity is void.~

This module can communicate to a microcontroller for an embedded system or a PC with RS-232C of TTL (1.9 ~3.6V single-end) level.
J2 terminal (20-pin) of this module is attached to a connecting cable. For the pin assignment at the terminal, please look at the table below.
Item Minimum Standard Maximum Unit Power Supply Voltage (VDD) 1.9 3.0 3.6 V Input Voltage at H level 0.7 x VDD VDD V Input Voltage at L level VSS (GND) 0.3 x VDD V Output Voltage at H level VDD – 0.3 VDD V Output Voltage at L level VSS (GND) 0.3 V

No Type of Signal No Type of Signal 1 RESET 2 GND 3 BR2 4 GND 5 SLEEP 6 GND 7 BR1 8 GND 9 BR3 10 GND 11 SUSPEND 12 GND 13 RXD 14 NC 15 TXD 16 NC 17 RTS 18 NC 19 VDD 20 GND
Serial Communication is specified as 8bit length, no parity, 16bit stopbit length, and hardware flow. The communication speed is determined by pin-assignments patterns of BR1, BR2, and BR3. Please look at the table below for the details.
BR3 BR2 BR1 Communication Speed 0 0 0 4800 0 1 0 19200 0 0 1 38400 0 1 1 50000 1 0 0 1200 1 1 0 2400 1 0 1 9600 1 1 1 57600 [Caution]
19200bps or slower communication speeds is highly recommended. AT 57600bps, the internal chip may drop few command lines because it cannot keep up its processing speed with communication speed.

This is an example of a DIY connection cable.
To use R232-C interface, please attach jumper resistors at R18, R19, and R20 on the PCB. The size of jumper resistor is 1608. Please configure the pin assignments of J2 terminal
- Table of J2 pin-assignment
|9-10|BR3|Please look at the next table (table below)|
No Type of Signal Using Jumper Resistor 1-2 RESET No 3-4 BR2 Please look at the next table (table below) 5-6 SLEEP Yes 7-8 BR1 Please look at the next table (table below)
11-12 SUSPEND No 13-14 RXD No 15-16 TXD No 17-18 RTS No 19-20 VDD 19:3.3V, 20:GND
The 19th and 20th pins are attached to an external power supply. The voltage of the external power supply is 3.0 ~ 3.3V. The 19th pin is attached to the + electrode, and the 20th pin is connected with the – electrode.
The serial communication is with 8bit length, no parity, 1but-stopbit length, and there is hardware flow. The communication speed is determined by whether each pin of BR1, BR2, and BR3 is attached with the jumper resistor or not. The relationship between the combinations of jumper resistors and speed of communication is shown below.
| BR3 (9-10) | BR2 (3-4) | BR1 (7-8) | Speed |
| Yes | Yes | Yes | 4800 |
| Yes | No | Yes | 19200 |
| Yes | Yes | No | 38400 |
| Yes | No | No | 50000 |
| No | Yes | Yes | 1200 |
| No | No | Yes | 2400 |
| No | Yes | No | 9600 |
| No | No | No | 57600 |
[Caution] AT 57600bps, the internal chip cannot catch up with the speed of communication and may not process all commands. 19200bps or slower is highly recommended.
