Adapting a TTL-232R-3v3 cable for an EQ8
Could one you electronic wunderkind please help me figure out which cable goes where - I've bought one of the 3.3 VDC TTL cables to use with my EQ8 with EQMOD. Bu I'm having trouble figuring out the cableing for the RJ45 (8P8C) plug. The data sheet lists the pinout for their 6-pin connector as:
1. GND - black
2. CTS# brown
3. VCC red
4. TXD orange
5 RXD yellow
6 RTS# green
The EQ8 manual gives the pinout for the hand controller (an 8-pin plug not 6) as:
1 and 4 GND
2 and 3 (no connection)
5 Tx
6 Rx
7 and 8 Vpp+
i just had a quick look at a Shoestring Astronomy USB2EQ5 cable and note that it uses 6 wires only with nothing in slots 7 and 8 whereas the Synscan hand controlled has wires in all 8 slots. Mystery deepens?
I'm a bit stumped.
