500-series scopes (53x, 54x, and 55x) and 127, 132, 133 have bays that take letter-series and 1-series plug-ins which typically control the vertical axis of the display. Two exceptions are the 555 and the 536. The 555 additionally takes two 555-specific timing/sweep plug-ins (21, 22, 21A, 22A) that control the horizontal deflection of the two beams. The 536 takes two letter-series or 1-series plug-ins; One controls vertical, the other horizontal, in XY mode.
The pinout changed significantly in the 20+ year run of the 500 series. Pins 1, 2, 3, 8, 16, and all power supply pins remained the same, however.
The Type T timebase plugin and it's host, the horizontal bay in the 536 also have a banana jack mounted above the main connector for retrace blanking.
580-series scopes use their own very similar plug-ins.
The pinout on the connector is as follows:
| Pin number | Function |
|---|---|
| 1 | Signal + |
| 2 | GND |
| 3 | Signal - |
| 4 | Trigger - 544, 546, 547, 549, late 555s, and 556 |
| 5 | Trigger + 544, 546, 547, 549, late 555s, and 556 |
| 6 | Sawtooth (556 only?) |
| 7 | Alt Timebase sync on 547 |
| 8 | Multi-Trace Sync |
| 9 | -150 V DC |
| 10 | +100V DC |
| 11 | +225V DC |
| 12 | +350V DC |
| 13 | 6.3V AC relative to pin 14 |
| 14 | 6.3V AC relative to pin 13 |
| 15 | +75V DC |
| 16 | Multi-Trace Sync |
