The Motorola RCH3000 is an SB9600 Desk Console for remote control of Astro, MCS2000, and iDEN radios.
Overview
The RCH3000 was intended for dispatch centers or offices where a normal radio control head and microphone would be impractical or would look out of place. The deskset emulates a Model 3 control head for the MCS2000 and iDen mobiles, or a W9 head for the Astro Spectra, Spectra Plus, and XTL5000 radios. Connections are made between the radio and the deskset via a junction box or directly to the radio via an accessory connector. Details about the installation and connection can be found in the installation section or in the manual.
Manual
I've scanned and uploaded the RCH3000 manual as I recently found one and I've not seen it posted anywhere else.

Connection to a Non-Consolette Astro Spectra/Plus/XTL5000
Prerequisites:
- An Astro Spectra/Spectra Plus/XTL5000 with a standard W-series remote mount TIB, with correct flash for a W9 control head. Low, mid, and high power should all work but they must be W9 radios.
- An RCH3000 with proper power supply and with the correct config settings as described in the installation manual above.
- A DB25 male connector, cat5 cable, and an RJ45 termination at one end
Making the Cables
One end of your cat5 run will be plugged in to the back of the RCH3000. Use the already terminated end of an existing cable, or crimp your own. Color code followed doesn't matter, but if you know the T568B standard it'll make things easier on the other end. Once you have a suitable RJ45 end in place, we can move on to the radio side of things. You will be using the J5/6 connectors on the front of the radio TIB, as all the needed signals are brought out to these two ports. Note: Motorola uses reverse pin numbering for their RJ45 connectors and has done so since the maxtrac era. Be careful! Looking with the locking tab on the bottom, pin 1 is on the right side of the connector.

Radio Programming
As far as the radio is concerned, the RCH3000 is just another W9 head. Glancing at the buttons on the deskset, you can see it's basically a standard W9 head with the button layout shifted slightly. (you can even use standard spectra control head buttons to change the labels on the RCH!)
