DS2151Q

12 RECEIVE MARK REGISTERS
The DS2151Q can replace the incoming data on a channel-by-channel basis with either an idle code (7F
hex) or the digital milliwatt code, which is an 8-byte repeating pattern that represents a 1kHz sine wave
(1E/0B/0B/1E/9E/8B/8B/9E). The RCR2.7 bit will determine which code is used. Each bit in the RMRs,
represents a particular channel. If a bit is set to a 1, then the receive data in that channel will be replaced
with one of the two codes. If a bit is set to 0, no replacement occurs.
