Huawei ATN 950B - Technical Specifications

CAUTION
Do not change the default setting of the DIP switch. Otherwise, the EPS30-4815AF is affected.
The DIP switch indicates eight bits in binary format (on: 1; off: 0). The default value of the eight
bits is 00000100. The functions of the eight bits are as follows:
l The first five bits indicate the local and remote power addresses. Bit 5 is the highest bit and
bit 1 is the lowest bit.
l Bit 6 sets the baud rate of communication between the monitoring module and equipment.
When bit 6 is 1, the baud rate is 9600 bit/s; when bit 6 is 0, the baud rate is 19200 bit/s.
l Bits 7 and 8 are reserved.
