Tobin Time

Note: This motor requires that your camera have the 1:1 drive shaft.

The 1:1 shaft is found on cameras made since about 1965, including the H-16 Rex-4 serial number 210'601 and higher; the H-16 M-4 serial number 214'401 and higher; the H-16 S-4 serial number 221'201 and higher; and the H-8 Rex-4 serial number 212'401 and higher. All Rex-5, M-5, SB and SBM cameras have the 1:1 drive shaft. The 1:1 shaft is to the left of the film plane mark and above and to the right of the I-T selection knob.

Powering

The TTL requires 12.6 volts DC for operation. Current draw is quite low, suitable for long-term unattended operation on battery power. Connection is with the industry standard "XLR" type 4-pin male receptacle, and with the industry standard polarity of pin 1 negative (-) and pin 4 positive (+). Acceptable range is 11 to 14.4 volts.
