Does anyone have the PROPER pinout for a DB-25 connector to the back of a XTL5K Consolette? My connector broke off and I'm seemingly missing that page in the binders I have. This is a 2 pair connection going to a Gold Elite System.
I have a new DB-25 adapter, just need to know which wire goes to which pin!

Re: Missing Schematic
Anyone?
I think I have it down to Pins 1, 3, 11 and 16 possibly but I don't want to let the white smoke out!

Re: Missing Schematic
This is what my manual shows for J2
Pin Signal Name Description
1 RX+ (LINE1+)† Receive high used with TRC desksets (TX and RX high for two-wire operation; RX high for four-wire operation)†
2 AUD_SHLD Ground: audio or analog
3 TX+ (LINE2+)† Transmit high used with all desksets (TX high for four-wire operation)†
4 FILT_AUD (DET_AUD)† RX filtered audio (RX detect or discriminator audio)†
5 A+ +13.8VDC or battery voltage
6 BUSY Busy line of data bus; 5V logic
7 BUS+ High side of bus data: 180° out of phase with BUS–; 5V logic
8 NC Currently not used
9 VIP OUTPUT 1 Vehicle interface output port 1
10 PTT* Push-To-Talk initiates a transmission; 5V logic
11 TX– (LINE2–)† Transmit low use with all desksets (TX low for four-wire operation)†
12 DIG_GND Ground for 5V logic signals
13 VIP INPUT 1 Vehicle interface input port 1
14 REMOTE_RX+ (SPKR_HI)† Remote deskset speaker high output (CAUTION: grounding this pin will result in damage to the radio) (Speaker high output)†
15 REMOTE_RX– (SPKR_LO)† Remote deskset speaker low output (CAUTION: grounding this pin will result in damage to the radio) (Speaker low output)†
16 RX– (LINE1–)† Receive low used with TRC desksets (TX and RX low for two-wire operation, RX low for four-wire operation)†
17 AUX_TX_AUD Linear transmit audio path used with auxiliary PTT
18 VIP OUTPUT 3 Vehicle interface output port 3
19 BUS– Low side of bus data: 180° out of phase with BUS–; 5V logic
20 RESET Data bus reset line; 5V logic
21 5V 5V for logic circuits
22 VIP INPUT 3 Vehicle interface input port 3
23 VIP OUTPUT 2 Vehicle interface output port 2
24 MONITOR* Allows activation of monitor (used with MRTI telephone interconnect)
25 SPKR_UNMUTE Signal indicating if the Consolette is receiving valid audio
* indicates an active-low condition
† indicates TRC information
NC indicates Not Connected

Re: Missing Schematic
So you appear to simply be running Tone Remote Control over a 4-wire connection. Not much to worry about in the 'white smoke' category.
