Appendix A – Remote Programming
1. Interface.
The DX602-C1 can be remotely programmed via an RS232C
interface. The data rate is set to 9600 Baud, 8 bits, no parity, 1 stop
bit and no handshaking signals. Data is ASCII encoded.
All commands must be terminated by a CR, LF or CR+LF.
2. Protocol.
a) Type “[enter]” to see the current frequency setting. The DX602-C1
reports “2296.0W 650W A”. The 2296.0 is the set frequency, the W
next to it indicates ‘wide bandwidth’. The 650 indicates the 6.50MHz
subcarrier that carries the data. The W following it indicates the
receiver is set for a ‘wide’ demodulator bandwidth of 250KHz. The “A”
in the end indicates ‘Automatic’ operation – i.e the DX602 will chose
the best antenna for video reception.
b) Type “T” to check tuner lock. The DX602-C1 reports
“ T1=L T2=L” implying both tuners T1 and T2 are locked.
c) Type “2379.0” to send a command to the DX602-C1 to change the
received frequency to 2379.0MHz.
d) Type “*1#2” to force the DX602-C1 to receive only Antenna 2.
The DX602-C1 will only receive video on Ant 2 input, and both
LEDs will be off. The DX602-C1 will report-
“ 2379.0W 650W M “. The M indicates ‘Manual’ mode of
operation.
e) Type “*1#” to return the DX602-C1 to automatic mode.
