•
Baud Rate - the EXT radio must be set for the same baud rate as the one used by the instrument.
Available range is from 300 to 115,000 BPS (default 9600 Baud, N, 8, 1).
•
Transmit mode – the EXT radio must be configured in cyclic sleep mode to strobe the data
from the external device or in no sleep for devices that output data at regular intervals.
•
Serial protocol – the EXT TXD and RXD data lines must be configured for the proper serial
protocol. Two modes are included, TTL serial (0 V – 3 to 5 VDC) or standards RS-232 ( -8 to -
12 VDC to + 8 - +12 VDC)
•
Pin 1 can be configured for VDC output (5V or 7-15 VDC) or input (DMC/AMP connection)
or for RXD for two-way communications.
•
Slide (DIP) Switch configuration for the EXT is depicted in

Notes:
1:
Baud Rate shown for ABPM-203 Continuous Air Monitor (CAM). For other non-MGPI CAM’s, refer to respective owner’s
manual for communication parameters and supported protocol (for example, AMS-4 – Baud Rate: 19,200, RadNet protocol
compliant).
2:
For TelePole connectivity, use AMP settings. RAM-ION is not supported at this time.
