Build Your Own Motorola Minitor 3/IV/V Pager Programmer and Programming Stand
This article describes how to build an cheap developer and programming stand for the Motorola Minitor Iii and Minitor Iv pagers. I've also included information about the Minitor V, although I don't take whatsoever starting time hand experience with this pager quite yet.
Background
The Minitor III, IV, and V two-tone pagers are computer programmable. The software is available from Motorola (software for the Three and IV costs coin, but the software for the V is available for free download from the Motorola website), and they besides sell a Universal Programming Interface (UPI) and programming cradle. The UPI costs near $230 and the programming stand (cradle) costs well-nigh $100. Yous tin can build your own developer and modify a standard charger to human activity as the programming stand. Total cost is less than $twenty.
The Programmer
A common questions is whether you tin can apply a Motorola RIB to program the pagers. The brusk answer is no. Motorola radios apply a information jitney to talk to the RIB, where the transmit and received data share the same wire. The pagers use separate TX and RX lines. Luckily, this makes the programming circuitry easier, even though you can't use a RIB for both pagers and radios.
The programmer shown here is basically a stripped down version of the Motorola UPI. A schematic of the full UPI is available at www.batlabs.com if you want to build the "total" version. My version doesn't include the comparator circuit or one.5V power supply, neither of which is necessary.
In reality, all that is needed is an RS-232 to TTL level converter. These can be bought online dirt cheap if you'd rather purchase one than make your own. Here's an instance:

Or, if you prefer USB, check this ane out:

An advantage of USB is that power to the converter is provided past the USB port and so you don't have to wire up any additional power supply. Just brand sure you lot install the drivers for the USB cable and select the correct COM port in the programming software.
If you want to build your own, read on. A schematic of my programmer is below. The circuit uses a MAX232 IC, which converts the +/- 12V RS232 signals from your estimator to 0-5V TTL signals that the pager uses. A 9V battery powers the circuit, so a 78L05 voltage regulator is used to driblet the voltage downwards to v volts. Resistor R1 and the LED just signal that the circuit is powered, and could be removed if desired. Resistor R2 is used for programming some types of 2-way radios (in conjunction with an external diode in the programming cable) and tin can be removed if desired.
I used a 3.5mm stereo jack for the connector on the "pager" side of the interface, since it'southward a readily bachelor and inexpensive 3-usher connector. I built the circuit on a prototyping PC board available at RadioShack. A few pictures of the completed programmer are shown beneath for reference.
Pager Interface
Note: If you already accept a programming cradle and desire to utilise it (instead of homebrewing your ain), here is the schematic for a cable that can be used to interface this programmer with the Mintor III/IV/V programming cradles:
If, on the other mitt, you lot want to whorl your own programing cradle, hither is some info that may be of apply to you lot:
This is the pinout of the Minitor III/Four pagers when in programming mode:
This is the pinout of the Minitor III/IV pagers when they are NOT in programming way, for reference:
This is the pinout of the Minitor 5 pager when in programming style:
Note that some of the pins take different functions when not in programming mode. To put the pager into programming mode, close the pager off and turn the aqueduct selector to "C". Then, turn the pager on while holding downwardly the squelch button. The pager volition emit a loud, long BEEEEEEEP. To betoken that it is now in programming style.
The Minitor III/4 Programming Stand (Cradle)
The programming circuit has to interface with the contacts on the bottom of the pager somehow. My first attempt at a programming stand up consisted of some bent pieces of wire screwed into a chunk of two×4. The wires were formed and then that they would touch the appropriate contacts on the bottom of the pager when the pager was held on the wires. See the picture below.
While this system worked, it certainly wasn't elegant or professional, and was inconvenient considering I had to hold the pager on the wires during programming. I wanted a cradle I could drop the pager into and not have to hold on to during programming. I decided to alter my pager'south charger to accomplish the task. The charger merely comes with 2 contact pins…power and ground. However, there are holes in the charger base where the other pins should be. All I needed to do was add two more pins (TX information and RX information) in the appropriate locations and I would be in business organisation.
Since the charging stand didn't come up with whatever extra pins, I had to find my own. If you take an extra, unused charging stand up you could steal the pins from that stand. I didn't accept an extra charger, so I didn't have extra pins. Instead, I modified some pins found in Deutsch connectors. A small spiral could probably also be used. I merely used what I had available. The pictures below evidence the pivot before modification, and after modification next to a Motorola pin.

The pins are held in place in the charger base past pieces of metallic that act as springs. Luckily, the charging stand had two unused springs, so I wouldn't have to make any. I just had to change the ii unused springs and move them to the locations I wanted. This involved cutting away part of the PC lath and soldering the springs into new locations. Unfortunately I forgot to take a moving-picture show of the charger before modification. A couple pictures of the modified charging stand are below.
A standard audio cable with iii.5mm stereo plugs on each end is used to connect the programmer to the cradle. Other connexion schemes are certainly possible…that's only what I decided to use. Happy programming!
Minitor Five Programming Stand up (Cradle)
The Minitor V charger can also be modified for employ every bit a programming cradle, although it requires a petty more intendance. Unlike the Minitor Iii/4 cradle, the Minitor V cradle has pads on the printed excursion board (PCB) that make contact with small springs that support the pins that in turn brand contact with the pager. The charging cradle is populated with the pins necesary for charging the battery and does not include whatsoever extra pins. However, in that location is another prepare of pins used for charging a spare battery. These pins are longer, but can be cut downwardly to fit the main cradle if you lot don't need the spare battery charging slot.
The two pictures below show both sides of the charger excursion board and the system of the pins in the charger earlier modification.
The motion picture below shows the modifications that will need to exist made to the circuit board to accommodate the two new pins needed for programming. The circuit board trace going from D26 to i of the existing pads will need to be cut in three places with a razor knife. A jumper wire volition so need to be installed to have the place of the circuit board trace that has been cutting. The remaining portions of the circuit lath trace will need to be footing very carefully to expose the copper underneath the solder mask. Be careful not to remove the copper from the PCB. A small area on the footing plane of the circuit board can likewise be exposed for connection of a ground wire for the programming circuit. Finally, wires will need to be soldered to the two new "pads" that accept been created for the programming pins.
The motion-picture show below shows the excursion board after modification.
The picture below shows the modifications to the rear "spare bombardment" pin for placement in the main portion of the charging cradle.
The pic below shows the underside of the cradle afterwards adding the 2 extra pins for programming.
