Place the module in a location which allows its handset plug to reach the handset jack on the voice terminal. Adhesive strips are provided for attaching the module to the voice terminal or other suitable surface.
If you plan to use the switch-hook to activate additional features, you may wish to connect the switch-hook lead to the voice terminal before mounting the M6500, since it will be necessary to open the voice terminal to attach the switch-hook lead.
Remove the existing handset and cord from the voice terminal and plug it into the modular handset jack on the M6500. Connect the handset plug from the M6500 "pigtail" to the handset jack on the voice terminal.
The audio output jack on the M6500 is an 1/8" mini-phono type. It connects to a high impedance recorder input. Connect a patch cord from this output to the recorders input. Switch 1 sets the output level.
If you are connecting to a remote recorder such as a data logger, install a single pair cable from the data logger to the voice terminal and use the mini-phono connector supplied with the M6500 to connect to the cable.
Alternate connections may be made using the modular jack on the M6500. See the Multifunction jack section.
Connect the AC adapter to the EXT PWR jack on the rear of the M6500. If you are using an adapter other then the one supplied, be sure it is capable of supplying 5 or 6 volts REGULATED DC at 50mA. Note the polarity as shown.
Alternate connections may be made using the modular jack on the M6500. See the Multifunction jack section.
The M6500 produces a beep tone audible to both parties for recording notification. The beep tone is a 200ms 1400Hz tone burst every 12-15 seconds. The beep tone may be turned on or off with switch 2.
Set option switch 3 for the type of trigger input: off for a positive trigger or on for a negative trigger. Incorrect setting of switch 3 will mute all audio from the M6500. If you are not using the switch-hook trigger lead, be sure this switch is set to off.
Switch-hook is a logical output from the voice terminal which follows the condition of the handset (on hook or off hook). It may be positive logic (ground on hook, +5v off hook) or negative logic (+5v on hook, ground off hook). An MA9 trigger lead cable supplied with the M6500 must be soldered to the points in the voice terminal which provide the positive or negative "trigger" and the ground reference.
Contact Avaya Communications (1-800-225-6907) to obtain a sketch indicating connection points for the specific voice terminal you are using.
Soldering equipment required would be a low wattage, pencil tipped soldering iron, and small diameter multicore solder (.028 or .032 inch).
Tinned wires should be trimmed to approximately 3/64 to 1/16 inch length before "tack" soldering to the P.C. board solder pad location. The solder pad will probably already have a component lead soldered in place. The added connection will be placed on the existing solder and heated momentarily to flow the solder on the wire together with the solder on the component solder pad. Do not allow solder to flow to other solder pads.
Route the loose ends of the cable assembly into the voice terminal base. Solder the black lead to the "switch-hook" logic connection point; this point will be indicated on the sketch for specific voice terminal. Solder the green lead to the "common" of 5V DC power supply in the voice terminal; this lead is the reference input to the M6500 Recorder Interface.
The cable you have connected should be secured to prevent strain on the soldered connections using a small tie-wrap or electrical tape. Re-assemble the set taking particular care to be sure the hook switch plunger and springs are installed correctly if they have been removed or disturbed.
The connector on the end of the switch-hook cable connects in the rear on the M6500. The white dot on the connector goes "up".
The multifunction jack on the M6500 is an RJ48C modular jack. It is intended for installations using multiple M6500's with central power and /or central recording. Several features are accessible from this port using a single 8 conductor cable. You may wish to connect to one or all of these features with a DW8 or similar type cord.
Note the pin numbers are for the modular jack on the M6500, and do not necessarily coincide with punch-down block numbering.
The M6500 RIM is primarily designed for use with "K" type handsets, having electret microphones. The Merlin MLX series voice terminals use this type of handset. Other voice terminals equipped with "K" type handsets may work with the M6500 RIM. The M6500 will not work on sets having carbon type microphones.
