CONNECTING THE CONTROL MODULES
The communications cable on the 1741 user handcontrol and on the 1742
attendant control each terminate in a plug that fits into the powerbase’s 6-pin
connector. The attendant control’s cable includes a Y-junction into which the
user handcontrol’s cable connects, as shown in Figure 7.
5-pin charger/programmer port
The user handcontrol has a 5-pin port that accommodates a battery charger
and a 1311 programmer (although not at the same time). The charger plug’s
three pins fit into sockets 1, 2, and 3. The programmer plug’s two pins fit into
sockets 4 and 5. Both plugs are designed to snap securely into the port.
Allowable current for a charger in this port is 8 amps continuous (12 amps peak).
The inhibit pin (pin 3) halts all chair travel during charging. Additionally,
it can prevent specific actuator movements.
